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.

Burger Boat Co. has weathered many a storm in its 150-year history, often changing direction to incorporate new technologies and adapt to changing market conditions. When the pleasure craft industry sank in 2009, it went after commercial work, and in the process had to develop a program for working in steel, which it hadn’t done in five decades or so. With the new process came new consumables from ESAB.

Q: I just ran across the article you wrote about gas metal arc welding (GMAW) machines in the July/August 2004 issue of Practical Welding Today. Your article was very informative. I will be purchasing a welding machine soon and would like to know if a GMAW machine can handle a motorcycle frame. Any...
