Resolving the challenges of welding coated steels

September 13, 2005 | By Kevin Lyttle

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.
