一、焊接原理所谓焊接,是指通过加热使熔化的锡铅焊料,借助于焊剂的作用,熔于被焊件的缝隙,若焊料与被焊件结合面上无杂质,则焊料中的锡与铅的原子会进入被焊金属的晶格,在焊接面间形成合金,使之连接在一起,形成牢固可靠的焊接点。如在结合处生成Cu_3Sn、Cu_6Sn_5、Cu_(31)Sn_8和其他金属化合物。二、焊接技术我们常用的焊锡是按一定比例组合的锡铅合金。助焊剂常用松香,它无腐蚀性,可溶于酒精制成“松香水”,也可直接用烙铁蘸着用,很适宜于铜件的焊接。市售的焊锡丝中间都已灌
First, the welding principle The so-called welding, refers to the melting of tin-lead solder by heating, with the help of the role of flux, fused in the weld was the gap, if the solder and weldment surface with no impurities, the solder in the tin and Lead atoms enter the lattice of the soldered metal, forming an alloy between the soldering surfaces, joining them together to form a solid and reliable soldering point. For example, Cu_3Sn, Cu_6Sn_5, Cu_ (31) Sn_8 and other metal compounds are formed at the junction. Second, the welding technology Our commonly used solder is a combination of tin-lead alloy by a certain percentage. Common rosin flux, it is non-corrosive, soluble in alcohol made of “rosin water” can also be used directly with a dip in the iron, it is suitable for welding of copper parts. Commercial solder wire in the middle have been filling
