铜的锻接（固相焊）难度高于铁，因铜氧化膜熔点高。传统做法是在还原性火焰下加热至近熔、快速对接锤合，或用银/磷铜钎料在接头处低温连接（实际为钎焊）。现代多用铜焊（BCuP 磷铜焊，自钎剂）或银焊。要点：接头清洁、搭接面大、加热均匀、趁热锤紧。

Forge welding copper is harder than iron (high-melting oxide). Traditional: heat near melt in a reducing flame, quickly butt and hammer; or use silver/phosphor-copper filler (brazing). Modern: copper-phosphorus (BCuP, self-flux) or silver brazing. Keys: clean joint, large overlap, even heat, hammer while hot. ---
