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.

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.
