Resolving the challenges of welding coated steels

When welding galvanized material, welders often encounter the problems of spatter, porosity, fume generation, and potential weld cracking as a result of the volatilization of zinc in the coating. When short-circuiting or spray metal transfer is used to join this material, the volatilized zinc rising from the plate surface causes the arc to become unstable and generate considerable spatter.Resistance spot welding of high strength steels (May 2003 problems welding 204b steelThe hardness profile of HS steel welds, which is related to the metallurgical characteristics of the steel and welding conditions used, can have a significant influence on the weld properties.
