一、概述手工铜衬焊是以手工实现单面焊双面成型的一种工艺方法,这是在老工艺铜衬焊的基础上改进而成的。这一工艺是用一根带有成型槽和散热槽的矩形紫铜块作为衬垫(不采用水冷装置)固定在焊缝反面,而使用结507焊条进行手工焊接,从而使反面焊缝同时成型(见图1)。 First, an overview Manual copper lining welding is hand-sided one-sided welding forming a process, which is based on the old process of copper lining welding improved. The process uses a rectangular copper block with forming and cooling channels as backing (instead of water-cooled) to the opposite side of the weld and hand knotted with a knot of 507 so that the reverse weld is simultaneously formed see picture 1).
