Through the practical use of the product, the hydraulic press as pressure test machine had certain feasibility; on the other hand, to using induction heating way makes overall melted copper ring in steel substrate and steel happens metallurgical combination, but steel didnt melt. Copper and steel re-melt deposit welding with induction heating can completely meet the products performance and application requirements. Key words 院copper and steel; re-melt deposit welding; induction heating; shearing strength of interface 为了满足我公司产品要求袁 需要在钢基体上附 再放上绝缘套圈袁在绝缘套圈中放入铜环袁然后加入 上一层铜袁不仅要求铜与钢基体实现冶金结合和很 保护焊剂袁最后将感应线圈套在绝缘套圈的外面,利 高的结合强度袁而且要求稀释率极低遥但常规的电弧 用我公司的IGBT 晶体管感应熔敷焊接生产设备进 堆焊稀释率往往大于10%[1] 不能满足产品性能要求袁 行加热焊接袁焊后焊接毛坯见图 1(b) 遥 采用铜钢感应熔敷焊接的方法却能够满足要求遥感应
