Arc thermal spray, also known as twin wire arc spray, is one of the older and simpler forms of thermal spray coating. Thermal spray technology has come a long way, from spraying basic metals and simple alloys to, now, spraying extremely hard ceramics and carbides. These advances don’t mean arc thermal spray is any less valuable. Thermal spray certainly isn’t the cure-all for everything, but each process has a specific fit in the coating world. Among many things, twin wire arc thermal spray is great for dimensional restoration, sacrificial corrosion coatings, custom alloy coatings, and bearing surfaces. Arc spraying is also fast and economical, which can translate into faster turnaround and better margins.

Gas tungsten arc welding (GTAW) is not commonly used in robotics because the process is erroneously believed to be too slow or complicated for robotics. But technological advances are changing that.

Q: I weld nuts to hot-stamped parts and am having difficulty getting consistent results. This includes parts where the nuts appear welded to the part, but sometimes pop off in transit to our customer. We also get inconsistent push-out test results. How come? I have asked this question many times and have gotten many different answers.

An outdoor barbecue grill is a great project for beginner welders. It’s practical and the materials aren’t very pricey. Here are instructions on how to fabricate your own open-framed BBQ pit.

Q: I have three different welding machines in my plant along with several robotic transguns. A couple of my machines are 50-kVA press machines and my transguns are 100 kVA. Why can my 50-kVA machines produce up to 35-kA secondary current, but my transguns only go as high as 18–20 kA?

Gas metal arc welding (GMAW) is one of the most-used welding processes in the world. Advancements in GMAW-related equipment, such as the ones highlighted here, keep it at the forefront of welding technology. 

Attracting and proficiently training welding students on a limited budget can be challenging, which is why Miller® developed MobileArc™ – an Augmented Reality Welding System that offers a convenient option that fits most budgets. Its highly-realistic, portable, and intuitive design is simple enough for students to self-learn so instructors can maximize efficiency in the classroom.

Several different wire feeding methods can be used when narrow-groove-gas-metal-arc-welding heavy-section materials that have nearly square butt configurations and minimal groove widths of approximately 13 mm (½ in.).

From robot kits to solder paste, this piece offers something for both the hobbyist and professional solderer.

Resistance welding (RW) is a thermo-electric welding process in which the weld is made by a combination of pressure and current. The process involves the joining of metals by applying controlled pressure and passing current through the metal area to be joined. There are several different forms of RW (e.g., spot, seam, projection, single-sided, bonding, cross wire, micro, flash, and upset welding) that differ primarily by the types and shapes of weld electrodes used to apply the pressure and conduct the current.

Resistance welding (RW) may not generate the volume of fumes created by gas metal arc or shielded metal arc welding, but capturing what’s produced during this process must still take place.
