METHOD FOR IMPROVING THE WELDABILITY OF HOT STAMPING PARTS

摘要

A method for improving the weldability of the hot stamping parts to improve the weldability of the hot stamping parts deteriorated in weldability due to the surface oxides is disclosed. The method for improving the weldability of hot stamping parts according to the present invention comprises a welding part selecting step to select an area inside a hot stamping part to be welded; a surface oxide layer removing step to remove a surface oxide layer from the area; and a hot stamping part welding step to weld the welding area of the hot stamping part from which the surface oxide layer is removed.
