铝的软钎焊看起来很简单 ,但在许多关键的地方需要严密的过程控制。粘着力强的氧化铝往往使通常的软钎焊显得很困难。由于铝合金钎料与通常的不同 ,要针对电腐蚀的影响 ,注意合金的选择。各种不同的铝合金、测定仪器及回火方法往往显示不同的钎焊结果 ,对于在各种钎焊作业中铝 Aluminum soldering seems simple, but in many critical places requires tight process control. Adhesive alumina tends to make normal soldering difficult. Since the aluminum alloy brazing filler metal is different from the usual one, attention should be paid to the choice of alloy in view of the influence of the galvanic corrosion. Different kinds of aluminum alloys, measuring instruments and tempering methods often show different brazing results. For various brazing operations, aluminum
