本发明所述,为一种划时代的焊接方法,利用这种方法进行堆焊时,可以在被加工母材上得到极其良好而平滑的焊道。一般在进行堆焊时,常因堆焊金属与母材的熔化混合而使成分稀释,性能劣化。因此,要保证高质量的堆焊,应尽量减小母材的熔化。但是过去采用的埋弧焊、MIG焊、TIG According to the present invention, it is an epoch-making welding method, and when surfacing welding is performed in this way, an extremely good and smooth weld bead can be obtained on the base metal to be machined. Generally in the surfacing, often due to melting of the surfacing metal and the base metal components dilution, performance degradation. Therefore, to ensure high quality surfacing, should minimize the base metal melting. But in the past used submerged arc welding, MIG welding, TIG
