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.

Resolving the challenges of welding coated steels

September 13, 2005

By:

The increased use of coated steels has resulted in an intensified search for solutions to the problems posed by joining these materials. High levels of spatter and welding fume, weld porosity, and poor bead shape are common. These problems lead to increased post-weld cleaning costs, reduced quality, greater rework, and an overall reduction in productivity. The right wire size and type, matched with the most appropriate shielding gas, can substantially improve gas metal arc welding (GMAW) performance on galvanized and coated steels.
