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.

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

welding technique

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

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.

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.

Post-Processing Welded Parts

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.

A Solution to the Skilled Welding Labor Shortage

An Industry In Distress

The manufacturing industry is in distress. There is a shortage of skilled talent and this gap is only widening. While manufacturing companies are able to make goods faster and cheaper than ever, there is a growing lack of skilled manufacturing employees to ensure that production continues. Industry projections from Deloitte and the Manufacturing Institute, among other industry analysts, predict that over the next decade, more than 2 million manufacturing jobs will go unfilled across the U.S.welder shortage infographic

This decline in skilled manufacturing workers is a result of two issues:

1. A very large portion of workers at or near retirement age
2. Incoming generations that are far less interested in the manufacturing industry

Welding is perhaps one of the susceptible areas in manufacturing to this trend because of the skill welding requires. The lack of skilled welders is causing large inefficiencies in the manufacturing industry due to understaffing and also causing pay rates of skilled welders to go higher and higher. Since it does not appear that upcoming generations will have a large participation rate as welders, the solution to the problem will likely be solved by the implementation of automated welding solutions.

  • Automated Welding Solutions That Deliver ROI
  • Automated Welding Solutions Come in a Variety of Forms

Automated welding robot machines, automatic welding bugs, automatic orbital welding machines, and even automated resistance welding equipment are being used to help combat the void created by a lack of skilled welders.

The lack of skilled welders is causing large inefficiencies in the manufacturing industry

Although full-auto arc welding machines are part of the remedy, they are not a panacea. Fully-automated welding solutions often require high capital expenditure, require expensive skilled programming personnel, and pose significant safety risks if not set up properly. The trade-off between the benefits of fully-automatic welding machines and their disadvantages led to the development of a new type of automated welding solution: the welding cobot.

 

Enter: The Cobot (a Collaborative Robot)

botx collaborative robotic welding table
The name cobot is short for “collaborative robot”. The increase of cobot development and deployment is revolutionizing the manufacturing industry. Welding cobots are unique welding tools that hold many advantages over other automated welding machines, especially traditional welding robotic systems. Cobots have special mechanisms and move in such a way that enables them to require little to no safety fencing.  While the potential for increased safety without extra costs is an excellent benefit, the most important benefit of cobot use in an automated welding cell is the reduced costs associated with installation and programming.

Robotic Welding Just Got Easier

Traditional automatic robotic welding machines require a high level of skill to program. Oftentimes many years of knowledge and experience are required to set up an automated weld cell; for this reason, many companies elect to hire contractors to do this work for them, adding to the already high cost. With cobots, the programming of the machine is much simpler. The programming software is engineered to be user-friendly, vastly decreasing the instruction time required to train a programmer. This not only lowers the initial costs of programming but also enables a cobot to have a high degree of flexibility. The decrease in programming time and safety equipment and the increase in flexibility typically result in a very short ROI timeline and reduce the dependency on skilled welders and automated welding robot programmers.

Red-D-Arc understands that many of our customers are not immune to the trends affecting the manufacturing industry as a whole. We know that maintaining a technological advantage is key to success. In order to help our customers fight increasing costs associated with the decline in skilled welding employees and complicated automatic welding machines, Red-D-Arc offers collaborative welding robot solutions.

Introducing The BotX-Welder:  The Robotic MIG Welder Solution

2 welders working with a cobot

The BotX-Welder is our cobot product solution for our customers. The BotX-Welder package comes with a UR10e cobot arm created by Universal Robots, a leader in cobot development. In conjunction with this robot arm, the Bot-X Welder system also comes with an XMT350 MPa MIG welder and S74 MPa Plus wirefeeder, both made by Miller Electric. A MIG welder torch and a welding fabrication table are also included to complete the cobot welding cell. While the hardware is state-of-the-art, it is the software in the BotX Welding cell that truly sets it apart. The robot arm in the Bot-X automated welding system is controlled by the Hirerobotics application, which can be used with either iOS or Android operating systems. The Hirerobotics app is much easier to use than a traditional automatic robotic MIG or TIG welding machine teach pendant.

A Welding App With All The Robotic Welding Routines You Need

 

What’s more is that the Bot-X Welder also comes with an expansive library of welding routines, with weld parameters made to fit almost any application. Welding can be automatically monitored and recorded through cloud connectivity. This allows remote users to view weld data from anywhere in the world as long as they are connected to the network.  The cost and risks of  new technologies are often high. Red-D-Arc eliminates the risk of failed robotic welding implementations by only charging our customers by the productive hour when using the Bot-X Welder. This enables users to try the machine out, use it as much as they need it, and get rid of it when it the work slows down. This probably won’t be a problem, since you’ll be able to keep customers happy with a quick rate of output and very high weld quality.  The pay-as-you-go system is much easier and more cost-effective than the traditional hiring and firing of personnel.

Maintaining a technological advantage is key not only to prosperity in the manufacturing industry, it is essential to survival. As more and more efficient means of weld, production is developed and as the number of skilled welding laborers declines, the pressure is on to adapt.

Red-D-Arc has always and will continue to support our customers through industry shifts. The Bot-X cobot MIG welder system is another way we help you keep ahead of the competition.

EX360 FieldPro Multi-process Welder

ArcReach® technology is an investment that results in a lot of time saved during welding operations.  With most welding equipment the operator needs to walk back and forth to adjust output voltage – sometimes over hundreds of feet – multiple times during a job. This results in hundreds of wasted hours and thousands of lost dollars over the course of a large project.

ArcReach technology enables welders to adjust the voltage settings right at the point of welding

ArcReach technology enables welders to adjust the voltage settings right at the point of welding instead of walking all the way to the power source and back.  Even worse, if the voltage settings are “just good enough”, the operator might not bother making the trip, resulting in lower quality welds.

Top 3 Advantages of Using Pulsed-MIG Welders

Facebooktwitterlinkedinmail

When MIG welding was first invented, it used a constant voltage source of electricity for the arc.  While this method is still used today, the invention of pulsed MIG (or MIG pulse) welders has allowed welders to realize several advantages over conventional MIG welders, several are listed below:

Pulsed MIG can be used to weld thin materials.  Conventional MIG welders run at a constant amperage whereas pulsed GMAW welding runs a peak and background amperage. The constant switching between these two amperages enables the welder to put out a lower overall heat input into the material.  This helps prevent blowouts on thin materials.

  1. There is less spatter than conventional MIG welders.  Pulsed MIG welders use peak electrical currents to cleanly burn the wire off at a high amperage.  It also employs a lower background welding amperage immediately after the peak electrical current to prevent the interaction of the electrical arc and the wire from becoming unstable.  This ultimately results in a reduced amount of spatter.
  2. MIG pulse welding is excellent for out of position welding.  At the same voltage and wire feed settings, conventional MIG tends to have a weld puddle that is larger and more fluid than that of pulsed.  MIG pulse welding has a more controllable puddle that prevents it from falling out when gravity is a concern during out-of-position welding. Furthermore, the reduced amount of spatter that can be achieved with this method makes it safer for the welder to perform the out-of-position operation.

Pre-weld and post-weld heat treating is critical for many welding operations. Without proper thermal manipulation, welds and heat affected zones can have mechanical properties that are undesirable. Worse yet, inadequate heat treatment can result in cracks and devastating weld failures. While temperature and time are the primary concerns when heat treating a weld, the heating method should also be considered diligently when selecting a process. Induction heating is one of the most popular types of heat treating methods, and rightfully so.

Pipe welders at work
The method you select for welding pipe will depend on the location where the welding is taking place, materials and pipe size.
For welding steel pipes in the open (e.g. pipe installation in trenches), manual arc welding (SMAW) is most common. This technique used is downhill using cellulosic electrodes (also basic electrodes are used for higher strength steel applications). A root pass and a hot pass are followed by the fill passes. The weld is finalized by the top pass. Welding units optimised for downhill welding are utilised.

Welding Smaller Pipes

For small diameter and short length pipes which are free to rotate, the pipe is rotated while the welding torch is held stationary. The processes used are MIG (GMAW) and TIG (GTAW). In the case of TIG welding a wire feeder is necessary. A process cell is best for this type of welding.

Welding Large Pipes

In applications involving larger pipe sizes, welding is generally carried out using the orbital process. MIG is usually employed, but TIG with automatic feed of the filler wire can also be used. Orbital process using closed head welding units is also utilized for applications where smaller pipes cannot be rotated.

There are a number of advanced methods of depositing pipe welds currently in use. These include precisely controlled short circuit transfer for root pass (Miller – Regulated Metal Deposition), optimized pulsed welding (Miller – Pro-Pulse) and high frequency waveform control (Lincoln – Surface Tension Transfer) in order to speed up and improve the quality of the pipe welds.

Red-D-Arc has a wide range of pipe welding equipment for rent including the following:
