The process of laser butt welding of zinc-coated steel ( SGCD3 and WLZn ) blanks was presented, whose edges were prepared by laser cutting. The properties of the butt joints, such as tensile strength, bending, stamping, weld shape, and corrosion- resistant were tested. The experiments of laser cutting and welding were carried out on a custom-made system designed, which is a set of equipment for wide sheet butt welding based on a laser cutting-welding combination process. The experiments proved the technological feasibility of laser butt welding for thin zinc coated steel sheets whose edges were prepared by laser cutting on the same equipment.
