The arc welding technology area focuses on the most commonly used arc welding processes, mainly GMAW/MIG, GTAW/TIG, SMAW/stick, and plasma. The articles and press releases cover processes and power sources, plus all of the related items—electrodes and wire, wire feeders, fixtures, manipulators, positioners, and power sources. If you need information on personal protective gear, ventilation systems, and safety practices for welders, see our Safety coverage area.

A Wisconsin metal fabricator created a 10-ft. replica of the Lombardi Trophy and mounted it in the yard outside of its Green Bay-based tailgate house. Why? Because Packer freedom is a way of life.
Even though GMAW is relatively simple process to execute in comparison to other welding processes, there are a lot of moving parts that will either make or break your weld. New welders have a lot to consider, including understanding the base metal, the type of weld necessary, how to set up the machine, and how the best to lay the bead. Knowing which is best for the application is often part of the challenge.

Metal artist Chris O’Rourke goes a little further than most artists do, focusing on attention to detail. Many fabricators are more than a little mystified as to just how he did what he did, and most are equally perplexed when they realize how much time and effort he puts into his work.
