Southern states find the winter months colder every year, leaving power grids strained as people warm their homes and businesses. Midwestern states continue to battle tornado weather during the spring. Even northern states are seeing an increase in electrical needs as temperatures soar higher in the summer. If you run a business or industrial complex, you understand just how important continued access to electricity is. You also know just how easily grids can become overwhelmed or powerlines can go down, leaving you in the dark; unless, of course, you’ve opted for an industrial generator rental. (more…)
A good generator rental can mean the difference between a profitable and failed project. Generators make it possible for you to source power during natural disasters and in areas without existing infrastructure. When sourcing a generator, you might wonder if buying is better than renting. You might also feel overwhelmed by the many different types of generators you can choose from. This is just the tip of the iceberg when it comes to the factors you need to consider. (more…)
Planning for emergency power outages due to weather, brown-outs, or natural disasters by using a generator rental can save your business thousands of dollars in lost revenues. However, to get the most out of your generator, you need to choose the correct size and type for the job.
The Importance of Choosing the Right-Size Generator
Cost-conscious business owners may be tempted to try to get by with an underpowered generator to save money, but this is not a good idea. Using the wrong size generator can damage both the generator and the equipment that is being powered by it, which can end up being more expensive than renting the correct size generator in the first place. When estimating your emergency power needs, it is better to choose a generator based on the high end of your estimate for several reasons:
Once you have determined the type and size of generator you need, the next big question is usually whether you should get a generator rental or purchase a generator outright. Several factors determine which route is best for you.
Advantages of Renting
The primary benefit of renting a generator instead of buying one is that the upfront costs are lower. The purchase price of a large industrial generator can be twenty to well over one hundred and fifty thousand dollars. If cash flow is a concern, renting may be a more attractive option, and the lower cost isn’t the only benefit.
Red-D-Arc’s Dry Ice Blasting Specialists are industry-renowned for delivering solutions centered around cleaning and performance maintenance, particularly in commercial/industrial paint operations where dry ice blasting often proves superior to conventional hand scraping or chemical methods for the removal of overspray deposits.
Here is one such example.
Project Scope and Development
A Wisconsin-based manufacturing company contacted Red-D-Arc inquiring about the feasibility of dry ice blasting for their paint operation. The process was to be part of a deep clean for one of the client’s paint booths with the goal of removing heavy overspray from walls, floors, windows, lighting covers, fixtures, and sprayers. Once the deposits were removed, the bare surfaces would undergo a protective clear coat application and the booth would then be returned to production.
Red-D-Arc’s Dry Ice Blasting Specialists were instrumental in reviewing the application, evaluating onsite compressed air requirements, and calculating removal rates and ice consumption estimates. They provided the client with a “clear picture” of the job scope, and they tailored a turnkey rental package specific to the customer’s environment and painting operation. (more…)
Collaborative robots like the BotX Welder are shaping the future of manufacturing. Rob Goldiez of Hirebotics joins robotics investor Marc Cuban and Enrico Krog Iverson of OnRobot to discuss the impact of collaborative automation technology.
Thisvirtual event will see the robotics thought leaders discuss their powerful visions of the future of manufacturing. The expert panel will share insights on how collaborative automation helps future-proof manufacturing companies, helping to build resilience and reduce risk as the world navigates unprecedented COVID-19 challenges where uncertainty is now the only constant.
2020 has been a year of uncertainty. As people try to manage their health and well-being during the COVID-19 pandemic, businesses and governments are trying to do the same. In the United States and Canada, many construction, manufacturing, and maintenance businesses have been deemed critical or essential. Examples include those in healthcare, energy, food and water, transportation, and utilities. Work continues, but not in the same way that it used to.
The pandemic is also forcing business owners to take a hard look at their balance sheets. Companies of all sizes are looking for innovative ways to work safely and effectively, while reducing costs. Rental equipment has a key role to play in supporting these innovations. There are three distinct benefits to renting equipment instead of buying equipment during the COVID-19 pandemic: cost, flexibility, and availability. Here’s what you need to know. (more…)
Red-D-Arc’s latest customer success story highlights the benefits of using induction heating in rotating equipment applications.
A client contacted Red-D-Arc to inquire about the use of induction heating to remove a coupling hub from a motor shaft. The hub was 12 inches in diameter and roughly 4 inches thick.
The overall work scope was straightforward: the client needed to remove an old motor and replace it with a new motor. The coupling hub had to be reused, so the hub would need to be removed from the old motor and installed on the new one. Two things made this job challenging: the location and the time limit. The work was to take place on an offshore platform. Use of an open flame was not an option, as it would have led to a safety violation. (more…)
Power generators are crucial to numerous kinds of projects that require electricity. These include onsite work, events, emergency operations, and many others. Industrial generators serve as a reliable source of electricity for projects carried out in remote locations where there is no access to grid power. They are also an excellent alternative for projects that might put too much strain on the grid. For sectors such as oil and gas, manufacturing and construction , and others that require a continuous power supply, power generators provide a steady stream of reliable power during potentially damaging seasonal fluctuations in the grid electricity supply. They can also provide backup power in emergency and recovery situations.
Whether as prime, backup, or supplementary power supply, power generators have to be in good working condition to function correctly and deliver on all their benefits. Power generators are made up of numerous constantly moving components operating at very high temperatures and pressures. The key to keeping them working optimally throughout their life cycle, despite these operating conditions, is proper maintenance.
Large Scale Paint Removal Job Using Dry Ice Blasting
A coating and refinishing company out of New Jersey recently contacted Red-D-Arc for support on a gymnasium ceiling project. The paint on the ceiling was failing and required a re-coat. The client wanted an efficient and environmentally friendly solution requiring minimal cleanup. Dry ice blasting was the method of choice.
Dry ice blasting uses solid carbon dioxide pellets to remove debris without causing damage to the surface being cleaned. The pellets are accelerated to supersonic speeds through a pressurized air stream. The pellets then sublimate on impact.
Blowout Preventers Increase Safety for Drilling Operations
A blowout-preventer (special valve or device used for preventing blowouts on oil and gas wells) which had been stuck together for 9 years is finally separated with the quick application of a Miller induction heating system from Red-D-Arc.
Erectors can save cost and time by taking this welding technique in-house
Large steel erection projects commonly require heat treatment for welding because of the thick materials used in structural steel construction. Proper implementation is critical; so often this work is outsourced. The perceived level of expertise to perform this work can make the prospect of using in-house personnel daunting. However, most welding contractors are actually fully capable of performing on-site heat treatment operations.
The two primary methods for heat treating metal are preheating and post-weld heat treatment(PWHT).Preheating is the process of heating the base metal to a specific temperature prior to welding to minimize the temperature difference between the welding arc and the base metal. This process helps to reduce internal stresses that occur as substantial temperature differences between the weld and the base metal normalize, which can cause cracking and distortion. Slowing the cooling rate also allows hydrogen to escape from the weld, which minimizes the potential for cracking.
Applications and Advantages in Tank Fabrication and Maintenance
In the fabrication of storage tanks, as in most other welding applications, there are two crucial processes that storage tank fabricators must carry out to ensure the final quality and durability of the tanks. They are weld preheating and post-weld heat treatment.
Preheating involves heating the material to be welded to a particular temperature before welding. This process reduces shrinkage by minimizing the temperature between the arc and the base material. It also removes moisture, lowers hydrogen, and slows the weld cooling rate. These reduce the risk of cracking, brittle welds, and failure of the welds. Preheating is crucial for storage tanks as they are to withstand high pressures during operation.

Other members of our South West Region team are working tirelessly to mobilize generators for all segments of need. A big thanks goes to Michael Stevens and all our supporting personnel to be able to deliver more than 100 generators in a matter of hours.
Special thanks goes to Dave Kendrick and his team, for their outstanding efforts preparing our Lake Charles building prior to the hurricane landing. Dave worked late into the night to provide us with the best chance of weathering the storm. In the pictures below, you can see we sustained minimal damage compared to other buildings located down the road and we are very fortunate to have come out of this storm as well as we did.
Seasonal events like heatwaves increase the usage of power-hungry amenities from HVAC units at homes to buildings to reactor coolant systems in nuclear power plants.
Fluctuations in electric power during summer peaks may cause hardware failures and the cessation of business-critical operations for banks, hospitals, FMCG, refineries, and other sectors that need a continuous supply of power.
This enormous strain on the power grid and unpredictable electricity supply could lead to the loss of investment worth hundreds of millions of dollars.
That’s where electrical power reliability can protect public health and infrastructure.
Industrial generator rentals provide alternative electric sources that offer a steady stream of high-quality power to minimize production losses and operational downtime.
Power plants can rely on diesel generator sets in their job sites as an efficient emergency power backup source to provide capacity in the event of rising demand or fluctuation in supply. (more…)
The shift to an electricity-dominated global energy mix includes microgrids transforming the way electricity supplies to industrial markets, commercial markets, and oil and gas markets.
The falling expenditure of microgrid control technologies is among the top reasons US electric companies now actively deploy them across 42% of the country’s projects. This number has quadrupled since 2014, while the installed microgrid capacity has tripled.
Microgrids Enhance Electric Network Resilience
Microgrids, also known as supplemental power resource systems, are network-connected or operate independently from any electric utility grid. They range from remote microgrids that power the electrical needs of rural areas to true microgrids that supply additional energy to localized businesses.
The hurricane season is arriving soon. A lack of an emergency plan could lead to severe losses such as possible business and financial collapse of the organization.
Per the Federal Emergency Management Agency reports, 90 percent of small businesses close shop if they cannot resume operations within five days after a hurricane strikes. Another 20 percent of these companies usually spend more than ten days a month on business continuity plans.
With industrial generator rental, you can install backup power systems in hurricane-prone areas to enable the facilities’ equipment to remain operational. That means, almost within ten seconds of a power outage, your backup generator ensures smooth operations for multiple days during this severe weather season.
Here are five tips to consider for power preparedness with standby systems:
TIG Welding is a cost-effective manufacturing process. However, several factors can significantly increase or reduce the cost-effectiveness and productivity of a welding project. These range from operational efficiency to the use of consumables.
In this article, we’ll go through 10 ways to significantly reduce welding costs and boost the productivity of welding projects.
1. Avoid Overwelding with TIG Welders
Overwelding occurs when a weld is larger than it needs to be. This is a common occurrence in the welding industry, especially with inexperienced welders. An overweld may result when there is no specified size in a design, when there is no fillet gauge, or when a big weld is created just to play it safe.
Overwelding is a significant resource drain; it uses more arc time, labor, shielding gas, and filler metal, which leads to higher costs. To put this waste into perspective, consider a 1/4″ overweld instead of a required 3/16″ weld: This results in a 78% increase in both weld metal deposition and arc-on time. This goes up to 177% when the overweld is 5/16″.
Increased cost and time are not the only negative implications of overwelding. Bigger-than-required welds tend to distort more because of the increased heat input. Also, excessive convexity may increase the likelihood of a weld failing due to fatigue. In groove joints, excessive reinforcements do not create stronger welds compared to welds that are flush (or just above) the base material surface.
To save resources and time, stick to weld specifications in designs, make use of a fillet weld gauge, and avoid excessive reinforcements on groove joints. A change in wire diameter may also be used to avoid overwelding.
2. Employ Weld Automation
Weld automation is the use of equipment that automates part or all of the welding process. Human operators, no matter how skilled, are susceptible to fatigue. They can also make errors during welding or other related activities (e.g., positioning and handling pieces of the weldment). These factors, coupled with safety concerns, can affect the productivity of welding.
There are numerous types of automation equipment that can greatly increase productivity and save cost. However, different levels of automation can be applied in welding, and the term automation doesn’t necessarily mean robotic welding. For example, hard automation is the use of weld positioners, manipulators, and turning rolls to keep a weldment in place. There are also fully automated setups in which the actual welding is carried out by robotic arms—this is known as robotic welding.
The use of automation makes welding safer, faster, more productive, and more cost-effective. Compared to humans, machines are quicker, more consistent, and less prone to errors. Machines are also easily programmable, thus reducing the cost of hiring, managing, and training human workers.
3. Use the Right Welding Process
Weld aesthetics To effectively boost productivity, it is important to review all these factors before selecting a welding technique. For example, welding is more precise than metal inert gas (MIG) welding but requires more skill. If aesthetics is an important consideration, a TIG Weldershould be used, as MIG would cause you to spend more time later on in finishing. There is no need to select the submerged arc welding (SAW) process, with its high deposition rate of, when your project only requires the 5 lb/hr deposition rate of stick welding.
To make sure that you are not consuming more resources than necessary you need to review all considerations. Also, selecting the wrong process may lead to the production of rejects.
4. Handle and Arrange Materials Properly
The proper handling of materials during welding is crucial to improving productivity. Valuable time is wasted when a welder has to stop a welding process, go somewhere else to look for (and procure) a needed welding accessory, return to the welding spot, and resume welding. Even more time is wasted when weldment pieces are scattered around the welding area. While these short interruptions may seem trivial, they add up to significant time-related costs.
Before welding begins, all consumables, welding accessories, and parts to be welded should be sorted out and arranged in proximity to the welder.
5. Properly Maintain All Welding Equipment
The importance of having equipment in excellent condition for productivity and cost savings can hardly be overemphasized, as faulty equipment may consume more resources while generating more waste. Frayed cables and faulty appliances can lead to voltage losses, wire feeding problems, and erratic arcs. Likewise, faulty gas systems can lead to gas leakage. All these contribute to the potential inefficiency of welding operations. There is also the problem of defective equipment producing poor-quality welds, which may lead to more rejects, compromised worker safety, and costly downtime. Investing in a comprehensive preventive maintenance program reduces costs in the long run.
6. Prepare Joints and Gaps Properly with TIG Welders
Adequate preparation of joints is required for a hitch-free welding process. To start, welding operators should carefully clean the surface of the base materials. This will help prevent contaminants, such as dirt and oil, from entering the weld puddle. Next, welding operators must ensure they have the right fit-up and no excessive gaps.
A poor fit-up can have numerous negative consequences. One example is the potential for distortion or burn-through, which compromises the strength of welds. Poor fit-up also leads to overwelding, as gaps increase the size of weld required to achieve the same load-bearing capacity. For example, a 1/4″ fillet is required for a joint when there is no gap. A gap of 1/8″ in that same joint would require a new fillet size of 3/8″ to achieve the same strength. That amounts to a 124% increase in filler metal consumption.
7. Control the Use of Consumables
Consumables such as shielding gas, filler metals, anti-splatter compounds, grinding wheels, back bars, and gun components account for a noteworthy portion of the total welding cost. As a result, their proper use is important in keeping costs low. Certain consumables should only be used when necessary.
Gas delivery systems should be checked regularly so that leaks can be identified and sealed off. Surge turbines and surge guards can be attached to the end of welding guns to measure gas surge and reduce pressure, respectively.
8. Boost Efficiency
Labor cost is the largest cost variable in any welding project. One way to reduce this cost and boost welding productivity is by ensuring efficiency in all operations. The following operations are all time-dependent activities that can be optimized:
Preparing the metal for welding
Preparing the joint
Preheating, if required
Tack welding components, if required
Positioning/repositioning, if required
Moving between welds
Interpass cooling, if applicable
Inspecting and testing for
Reworking/repairing of welds and subsequent
Post-weld heat treating, if applicable
It is evident that a lapse in one operation can have a domino effect on the operations that follow it. For example, poorly prepared joints can lead to overwelding, which in turn can lead to avoidable grinding and polishing. Likewise, poor positioning may lead to reworking and repairing of welds.
While inefficiencies in operations may be difficult to track and measure, the rewards are worth the effort. An effective way to spot inefficiencies is as follows: If step 2 is a required process for step 3, then all is in order. However, if step 2 is carried out to correct or optimize step 1, then there are inefficiencies inherent in step 1.
Another way of boosting productivity is by using technology that enhances efficiency. One of which is with cable length compensation (CLC™), adjust while welding (AWW™), Auto-Line, and SuitCase™ wire feeder which delivers smooth wire feeding with accurate, consistent speed. These boost productivity and reduce labor time and cost.
9. Minimize Rejects and Reworks
When a reject is produced, 100% of the filler material, shielding gas, electricity, labor, and time used is wasted. This is terrible for cost savings. Reworks also result in wasted time, resources, and labor. Ensure that through skill and efficiency, rejects and reworks are eliminated when using TIG welders.
10. Prioritize Welding Safety
While they do not directly contribute to welding costs, workplace accidents are never desirable nor do they contribute to the efficiency of any production environment. Worker safety should always be a top priority in any company, especially when working with TIG welders.
Ensure that you take all necessary precautions and follow the pertinent guidelinesand regulations to maintain the safety of welding operators throughout a welding project. High-quality safety gear and comprehensive safety plans help to prevent injuries and save costs in the long run.
The construction industry is responsible for the creation of all kinds of structures with varying sizes, levels of complexity, and uses. From simple, small structures such as family homes to large, complex ones like bridges, dams, and manufacturing plants. Structural integrity and durability are the most important considerations in this industry. This is why the construction industry employs a very large quantity of metals. In the United States alone, more than 40 million tons of steel are used annually in the construction industry. The majority of this quantity is used to create structural frameworks. This is where welding plays an indispensable role in construction.
Welding technologies are widely used in the construction industry, mainly for the fabrication of structurally sound metal frameworks by fusing various metals components. It is also used to create and maintain non-structural components. Some of the welding used for construction is pre-fabricated in a shop environment while other parts of the welding process are done on-site.
Applications of Welding in Construction
Construction comprises numerous industries, including transportation, oil, andgas, telecommunication, power, manufacturing, many others. The construction industry is very broad & diverse and is divided into three major sectors which differ by the type of structures they create. These sectors are Building, Infrastructure, and Industrial.
The application of welding is crucial to all three sectors.
As the name suggests, the building construction sector involves the creation of structures in which people can dwell and carry out their activities. This sector is further divided into residential and non-residential. Building construction mainly employs welding in the creation of structural frameworks from metal components. Welding is used for connecting steel I-beams, trusses, columns, and footers, to support the walls, roof, and floors of a building. These components are cut to shape and size, lifted into position, and welded together.
Structural welding is not employed as extensively in small buildings, as it is in high-rise buildings that require thousands of metal joints. Welding in building construction is also used for the fabrication of non-structural building components such as firewalls, stairs, handrails, and floor joists. Furthermore, welders work with other professionals in setting up various systems in a building. These include:
Electrical systems – creating electrical conduits Construction for laying wires.
Plumbing systems – installing water supply and wastewater drainage pipes.
Ventilation systems – installation of vents and ventilation pipes.
Fuel systems – installation of gas supply pipes.
This sector is responsible for the creation of infrastructures such as bridges, dams, railways, stadia, water supply systems, highways, and wastewater management systems. The application of welding in infrastructure construction is mainly structural. This is because most of the structures created in this sector are megastructures that completely depend on structural reliable metal frameworks created via welding. Certain infrastructure such as bridges can be made almost entirely of metal. Others such as dams and water systems require a lot of pipe welding.
Industrial construction covers all structures that are utilized industrially. Structures created by this sector hardly stand alone but are usually part of a large system of numerous components and structures that work together for specific purposes. Such systems include manufacturing plants, refineries, mills, power generation stations, and many more. Industrial construction is considered the most diverse sector within the field as it cuts across numerous industries. The applications of welding in this sector are as diverse as the sector itself. TIG welders are used for the fabrication and maintenance of structural frameworks, pipelines, industrial equipment, and support structures for large components.
Welding Technologies Employed in the Construction Industry
The construction industry has a wide range of welding needs. Most existing welding technologies have one use or the other in the industry. Some of these and their uses are as follows:
SMAW: Also known as arc welding, submerged metal arc welding (SMAW) is mainly used for welding steel structures.
FCAW: Flux-cored arc welding is considered more convenient than its submerged arc counterpart. This technology is widely employed in fabrication using structural steel as well as heavy equipment repair
GTAW: Gas tungsten arc welding (GTAW), also known as TIG welding, is crucial for its compatibility with various metals including stainless steel, aluminum, bronze, and copper.
GMAW: Gas metal arc welding (GMAW), popularly known as MIG welding, is employed for both structural and non-structural purposes.
Application-specific welding systems employed in the construction industry include stud welders such as ProWeld Arc and pipe welders such as the PipeWorx welding system.
Benefits of Welding in the Construction Industry
The importance of structural integrity and durability in construction can hardly be overemphasized as structural failure can lead to a devastating loss of life and resources. Structures created weigh thousands of tons and are expected to last for hundreds of years. With the high strength and durability of weld joints, stakeholders in construction can rest assured that there’s nothing to worry about from the point of the framework.
Productivity is crucial to saving costs, resources, and time on any construction project. Productivity in a project is dependent on the efficiency of the processes involved. In terms of advancing construction efficiency, welding is at the forefront. While welding itself is a highly efficient process when using the right equipment, several other technologies have been incorporated into the process to make it even more efficient. Some of the technologies used in welding that are particularly beneficial to the construction industry are as follows:
This technology saves builders thousands of dollars and increases speed and productivity by eliminating the need for a welder to move to and from a power source to make necessary adjustments during welding. This is particularly helpful in high altitude welding where the actual welding may be 100s of meters above the ground where the power source is located. Some of the solutions that make up ArcReach include Cable Length Compensation (CLC™) which automatically adjusts the delivered voltage based on the cable length to ensure that the set voltage is always supplied; and Adjust While Welding (AWW™), which allows the operator to remotely adjust weld settings right from where they are working.
Weld Automation Equipment
Types of automation equipment that increase efficiency and accuracy include automatic wire feeders, welding manipulators, turning rolls, and welding positioners which are used to hold and rotate the pipe or other weldment.
Multiprocess TIG Welders
Some welding projects require more than one welding technology at a spot. It is stressful enough to switch equipment not to imagine doing this at heights where you would need to ascend and descend repeatedly. Multi-process welders eliminate this problem by combining various welding technologies into a single compact unit. In addition to all these, another factor that boosts productivity is the portability of welding equipment. This is appreciated when work has to be carried out over rugged terrain, at height, or in relatively small spaces.
The construction industry has a wide range of fabrication requirements. One of the numerous reasons why welding is indispensable in construction is its flexibility. For any size, work environment, or material, there is a suitable welding technique. For example, 5 cm diameter pipes can be welded as good as 50 m long beams and columns. Also, the various metal grades used in construction are all compatible with one welding technology or another.
Compared to many other manufacturing processes, welding is relatively cost-effective. To save even more, contractors and other industry stakeholders can simply rent high-quality TIG welders equipment, saving thousands of dollars on capital spending. If you are considering long-term continuous use, leasing your welding equipment might be an option to consider.
