The Importance of Proper Welding Operator Training

The weld pool in different processes may look different. For this reason, operators should be trained on “reading” the weld pool for the process at hand. There is no substitute for practice.
To gain more business in the face of a skilled labor shortage, fabrication shops need welding operators that are familiar with a wider variety of welding processes and materials and can take on new jobs to set their shops apart. Proper operator training plays a key role in reaching these goals.

Increasing Aluminum Weld Strength and Quality

4943 filler metals offer approximately 20 percent higher tensile strength compared to 4043 products and do not rely on dilution of the base material or increased operator skill to create a quality weld. It is also sometimes possible to create smaller welds and gain the right weld strength in a single pass, which eliminates the additional weld passes required with 4043 products, increases productivity and minimizes costs for the filler metal itself.
Aluminum is popular in many fabrication applications, but welding the material presents challenges of cracking, porosity and burn-through on thinner sections. Here are some critical insights on how to combat these potential problems. 

Weathering Steel: Taking the Guesswork Out of Filler Metal Selection

Weathering steels have small additions copper, nickel and chromium that help improve the corrosion resistance of the steel to atmospheric sources. 
Weathering steel offers excellent resistance to atmospheric corrosion caused by rain, snow or humidity. During the welding process, the filler metal type and the manner in which it is applied determines whether the resulting weld will match corrosion resistance or have the same reddish appearance, more commonly known as color match.

Considerations When Selecting a Filler Metal (Part Two)

Filler metal has a significant impact on the quality, productivity and cost of a welding job, so it’s worthwhile to take the time to make the right selection.
Although the effect of various elements in filler metals can be rather complex, a review of their general properties can also help welding operators determine which filler metal is ideal for the job. It is important to consider the properties needed in a completed weld when making the filler metal selection.

Ways to Get the Most Out of Your MIG Gun Consumables

Nozzles should be cleaned at least every other welding cycle in a robotic welding operation to prevent spatter buildup that can lead to poor gas shielding or cause short-circuiting between the contact tip and nozzle. Heavy-duty consumables are recommended for high-temperature robotic welding applications. If the robotic welding operation calls for a heavy-duty retaining head, pair it with heavy-duty contact tips. Always check the torques of the body tube and end fittings regularly to prevent loose fitting cables that can cause overheating and lead the robotic MIG gun to prematurely fail.
Here are a few of the best practices that every welding operator should know when it comes to choosing and maintaining nozzles, contact tips, retaining heads and gas diffusers, and cable.

Tube & Pipe Fabrication: Welding

With the new Tube and Pipe Weld Monitoring System from Xiris, tube and pipe fabricators can remotely view their live TIG, plasma or laser welding processes to clearly see if defects such as dross or porosity develop as the weld pool solidifies and monitor the condition of the weld tip, shielding gas and material fit up.
Here are some of the advances in tube and pipe welding equipment and accessories that are now available to help shops make money while meeting demands for more complex geometries, tougher materials, faster speed and higher quality.
