Arc Welding

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.

Modified GMAW for root passes

April 15, 2008 | By Jim Cuhel

Many fabrication shops that do a lot of stainless steel tube and pipe welding are in a bit of trouble these days. The problem isn't a lack of work, of course—it's a matter of trying to handle too much work with too few resources (skilled welders). They can ask their fabricators to work harder or faster, but that goes only so far. Can a new technology help them get more output from their existing employee base?

Welding development simulation software

Virtually welding

March 11, 2008 | By Tim Heston

Today several companies offer technologies that help beginning welders get that hand motion just right. None claims that the technology will replace the real thing, of course, but they do say that training in the virtual world can give students a significant leg up by the time they weld for the first time. It helps teach students what really happens between the welding arc and workpiece, why certain hand motions produce good beads while other motions don't. And it also may help introduce welding to students who wouldn't have given the trade a second thought.
