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.

Many structural steel fabricators are loyal to shielded metal arc welding (SMAW). But technology advancements in the wire feed process known as flux-cored arc welding (FCAW), paired with an increasingly competitive market, have changed the landscape of structural steel environments, and by extension the opinions of the most loyal SMAW users.
