恢复镀件可焊性的简易处理方法为了提高焊片、焊接头等一类黄铜制件的可焊性，通常在其外表镀锡、锡铅合金或锡铈合金等。这些镀件如果存放时间太长，表面仍然会氧化，使可焊件降低，故一般规定，焊接镀件需在３个月内，最多不超过半年用完。当超过此期限，可焊接性差的镀... In order to improve the solderability of a kind of brass parts such as welding lugs and welding heads, tin plating, tin-lead alloy or tin-cerium alloy are generally adopted in the appearance. These plating pieces if the storage time is too long, the surface will still be oxidized, so that weldable parts to reduce, so the general provisions of the welding plating in 3 months, up to no more than six months run out. When more than this period, poor weldability plating ...
