Abstract: It is not necessary to remove the coating in advance for laser welding of zinc-based coating hot-forming steel. Under the condition of good quality of shearing edge, laser spot defocusing welding without wire filling can ensure the quality of welding seam, and achieve the tensile strength ≥ 1500MPa and elongation ≥ 5% after hot stamping. The zinc-based coated hot stamping steel have advantages of good forming quality and high corrosion resistance, because zinc has the function of cathodic protection, the zinc-based coated hot stamping steel can protect the substrate and the weld through the sacrificial anode.
