[0002] Metal welding is a manufacturing or sculpture process for joining metals. During the welding process, the workpiece and solder melt or do not melt, forming a weld that directly connects the materials. Existing conventional welding has many defects, which can be divided into two aspects. On the one hand, there are internal defects, which are manifested in the presence of internal air holes, slag inclusions, internal cracks, incomplete penetration, and internal fusion.
