The widespread application of copper inevitably involves issues related to copper welding. In ancient times, copper and its alloys were mostly joined by brazing and forge welding, whereas now fusion welding occupies the main position. However, there are many issues in copper joining.

When using resistance spot welding and seam welding, similar difficulties are encountered due to copper's high melting point and its excellent electrical and thermal conductivity. In addition, currently, widely used copper joints in motors are connected using traditional silver-based brazing alloys, which consumes a large amount of silver each year. A large or medium-sized motor manufacturing enterprise spends hundreds of thousands to millions of yuan annually on purchasing brazing materials. At the same time, using the brazing process not only requires high preparation standards for the brazed joints, but it is also difficult to ensure the brazing gap, and joints often detach due to brazing seam defects, causing significant economic losses.
