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.

Erectors can save cost and time by taking this welding technique in-house

preheating process pipe

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

storage tank farm

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.

Pre-Heating

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.

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 will go through 10 ways to significantly reduce welding costs and boost the productivity of welding projects.

 

1. Avoid Overwelding

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 weld size in a design, when there is no fillet weld 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: The overweld 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″.

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 usedin the construction industry, mainly for the fabrication of structurally sound metal frameworks for by fusing various metals components. It also used to create and maintain non-structural components. Some of the welding used for construction is on 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 and gas, 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.

In welding, like in many other manufacturing and fabrication processes, the process is not complete until the necessary post-processing has been carried out. Post-weld operations are usually performed for reasons such as improving mechanical properties, relieving stress, and improving aesthetics. The two most common Post-weld operations are Post-Weld Heat Treatment (PWHT) and Finishing.

Post-Weld Heat Treatment

During welding, the welded materials are exposed to very high temperatures that can cause micro-structural changes in them. Also, residual stresses build up in welded materials when they are allowed to cool naturally.  If left unaddressed, these stresses and structural changes can severely compromise the mechanical properties of a material and can lead to failure during use. To prevent this, PWHT is required for welded parts. There are two major types of Post-weld heat treatment and they are as follows.

How Welding Automation Can Bridge the Skill Gap in the Manufacturing Industry

bugo welder

Welding automation has been around for a while, but recently its role has grown exponentially in manufacturing. For years, the welding industry has faced a skill gap, which is expected to grow wider in the coming years. To combat this, employers are adopting automated welding equipment to increase the efficiency of weld operations.

What Is the Skill Gap?

The “skill gap” describes a discrepancy between the skills held by job seekers and the skills employers need. This leads to a paradox where there’s a large pool of applicants, but companies aren’t able to hire workers with the appropriate knowledge and skill set. This has led to increasing welder salaries as manufacturing businesses compete to attract skilled workers, and even then, many positions are left unfilled.

Why Is It Happening?

Two main factors are contributing to this situation: a lack of qualified applicants entering the workforce and an increasing number of employees seeking retirement. Interestingly, these two issues may be caused by social factors rather than economic ones.

Few People Entering the Workforce

The newest generation entering the workforce is the most educated in U.S. history, which is a positive thing in most regards. However, it means that fewer young people are going into trades such as welding. There’s also a feeling among parents that welding, ironwork, construction, and other industries that require hard labor are dangerous or low-paying and therefore not worth pursuing. This has created a push toward white-collar jobs despite the high wages and many benefits offered in the manufacturing field.

With a huge percentage of employees planning to leave the workforce within a couple of years, thousands of positions will open at once and, unfortunately, be left unfilled.

Many Welders Are Reaching Retirement Age

The majority of current trade workers are from the Baby Boomer generation and are nearing retirement. With a huge percentage of employees planning to leave the workforce within a couple of years, thousands of positions will open at once and, unfortunately, be left unfilled.


What Is Welding Automation?

pipe on roller
Welding automation is the term used to describe the use of equipment  which automates all or part of the welding process.  The term hard automation is sometimes used to describe the application of positioning machines designed to hold and manipulate the weldment (object being welded).  Automated welding doesn’t necessarily mean robotic welding, rather it is simply the application of automation technologies such as positioners, manipulators and turning rolls to the welding process. The weldment may be positioned for manual or automated welding processes.  For example a pipe may be rotated on a positioner while being welded by a hand held welding head or by a welding head fixed to a manipulator arm for a fully automated set up.


How Can Automation Be a Solution To Labor Shortages?

Primarily, welding automation solves the skill gap dilemma by filling positions with machines instead of people. However, the switch to robotics can offer companies several advantages and will likely continue to transform how welding is done.

Cost-Effective

While the purchase and installation of a machine may be expensive initially, businesses can save money in the long run. There are many financing options available for commercial enterprises to purchase equipment, making the process more affordable, and employers don’t have to worry about costs associated with hiring, such as wage, benefits, and professional development.

Consistent

Machines can produce higher quality goods more consistently than human workers and work much quicker, which means more production and profits. Having fewer mistakes also means less waste and more products available for sale.

Programmable

Perhaps the most advantageous quality of machines is their ability to store welding routines and settings. Human workers must dedicate time and energy to learning a new skill and are inevitably bound to make mistakes along the way, costing the company. Machines, on the other hand, perform actions exactly as they are instructed. This means you can easily alter a robot’s role by changing the programming without having to deal with a learning curve. Many modern welders come with pre-programmed routines and settings and are able to make appropriate adjustment automatically with some basic input from an operator.


What Should Manufacturers Know About Implementing Automation?

workers with horizontal tig pipe cladderWhile welding automation technologies have evolved significantly, implementation still has its challenges, especially for businesses that are just starting to automate their welding operations. For example, though it isn’t actually the case, workers may consider the shift to automation as a threat to their livelihoods. You can ease this fear by communicating with the employees about the ways automation helps improve in the production process – ensuring that a company remains competitive. It also makes the work of welding safer and less strenuous and allows them to focus on higher skilled, more interesting welding tasks. In the case of welding robotics, assigning a robot to a necessary but repetitive task can free up workers for roles that require a human’s problem-solving skills. Collaborative robots (cobots) are designed to work in tandem with human workers and offer great gains in welding productivity.

You also face the challenge of finding the right equipment for your needs and incorporating it into your line operation. These issues should be carefully researched before you make any commitments.

In determining a welding automation supplier, you’ll want to establish an ongoing relationship with a company that’s able to address both startup and longer term issues that accompany a transition to automated welding:

  • Installation
  • Employee training
  • Maintenance of equipment
  • Replacement parts
  • Repairs
  • Upgrades

You’ll want to work with a company that has a thorough solid understanding of your industry and offers reliable technical and customer support.
