前言在铝合金钎焊技术中,采用真空钎焊可以克服熔剂钎焊过程中的一系列缺点,提高产品质量,缩短生产周期,排除污染,并从根本上克服残留熔剂所引起的产品腐蚀问题。早在六十年代初期,国外就在试验室中开展了铝合金的真空钎焊的研究,并证实了它的可能性。近年来,随着铝合金真空钎焊技术的发展与完善,其应用范围正在迅速地扩大。近些年来,国内各有关单位也已开展了 Preface In the aluminum alloy brazing technology, vacuum brazing can overcome a series of shortcomings in flux brazing process, improve product quality, shorten the production cycle, eliminate pollution, and fundamentally overcome the corrosion caused by residual flux corrosion problems. As early as the early 1960s, foreign countries carried out vacuum brazing of aluminum alloys in laboratories and confirmed its possibility. In recent years, with the development and improvement of aluminum alloy vacuum brazing technology, its application range is rapidly expanding. In recent years, various domestic units have also been launched
