我厂在制造涂釉线绕耐高温电阻时,设计要求将锰铜导线BMn40-1.5φ0.12绕在陶瓷骨架上15～16圈,其始端末端与装在陶瓷骨架两端的紫铜丝T2Yφ0.38引出线熔焊在一起。其焊点要圆滑,不应超过1毫米。为了满足这个要求,就必须用一种专门的焊枪才能完成。在国内我们曾走访一些工厂和焊接研究所,都未见过此种焊枪,仅仅在国外制造电阻的公司见到和使用过这种焊枪。
I plant in the manufacture of coated glaze around the high temperature resistance, the design requirements of the manganese copper wire BMn40-1.5φ0.12 around the ceramic skeleton 15 to 16 laps, the beginning of the end of the end of the ceramic skeleton with the ends of the copper wire T2Yφ0.38 Lead wire welded together. The solder joints should be smooth, should not exceed 1 mm. In order to meet this requirement, it must be done with a special welding torch. We have visited a number of factories and welding institutes in the country, have not seen such torch, only to manufacture resistance in foreign companies to see and use this torch.
