前言 铝合金钎焊目前较广泛使用的是两种工艺方法。一种为钎剂钎焊;另一种为真空钎焊不论使用那种钎焊方法,人们普遍关心的问题都是钎缝致密性问题,即构件的钎透率问题。围绕着这个问题钎焊工作者进行了工作,并取得一定的成效。特别是“钎焊填缝机理研究”一文的作者提出了一些独特的见解。 Preface Aluminum brazing is currently more widely used are two processes. One for the brazing flux; the other for the vacuum brazing Regardless of the kind of brazing method, people are generally concerned about the problem of dense brazing seam, that is, the issue of the penetration rate of components. Brazing workers around this issue have been working and have achieved some success. In particular, the authors of “A Study on the Mechanism of Brazing Sealant” put forward some unique opinions.
