活性化焊接(A-TIG)作为一种优质、高效的焊接方法最早是由Gurevich与Zamkov在20世纪60年代提出的,但是直到20世纪90年代末期才在欧美国家的科研机构开展广泛的研究[1]。A-TIG焊接工艺是焊前在母材表面涂覆一薄层活性剂,在相同的焊接规范下,同常规TIG焊相比,可以大幅度地提高焊接熔深。1、试验方法试验采用尺寸为150mm×150mm×8mm的AZ31B变形镁合金板材作为
Activated Welding (A-TIG) was first introduced by Gurevich and Zamkov in the 1960s as a high-quality and efficient welding method, but it was not widely studied in research institutes in Europe and the United States until the late 1990s [ 1]. A-TIG welding process is to apply a thin layer of active agent on the surface of the base metal before welding. Under the same welding standard, the welding penetration can be greatly improved compared with the conventional TIG welding. 1, the test method The test using a size of 150mm × 150mm × 8mm AZ31B deformed magnesium alloy sheet as
