Abstract
Provided is a steel welding component having a steel welding blank with an aluminum or aluminum alloy coating. The welding blank is composed of a steel substrate and coatings comprising an intermetallic compound alloy layer contacting the substrate, and a metal alloy layer on the intermetallic compound alloy layer. On at least one of the coating surfaces of the welding blank, the coating within an area to be welded has been totally removed, and an end face of the coating on the side of the coating within the area to be welded removed has an angle of β being 0-80° with a plane vertical to a surface of the substrate which is parallel to the welding seam. Also provided are welding methods for the steel welding component. The steel welding blank provided ensures the tensile strength, elongation, and corrosion resistance of a hot-stamped welded joint.
