摘要
本文通过对铝及铝合金焊接性分析,从焊接工艺特性因素入手,详细的阐述了铝及铝合金的焊接过程中的易造成氧化、产生裂纹,发生机械性能降低等焊接特点以及其防止产生缺陷的措施。并结合实际生产说明了防锈铝球形反应器有色金属的特殊焊接工艺要点和方法。从而解决了5A02铝合金焊接时易产生缺陷的问题,大大的降低了球形反应器的焊接难度。
In this paper, the welding characteristics of aluminum and aluminum alloy, such as easy oxidation, crack and low mechanical properties, and the method to prevent these defects are described. In combination with the practical production, the key points and methods of the special welding process for the nonferrous metal of the antirust aluminum spherical reactor are described. So as to solve the problem of 5A02 aluminum alloy welding defects and greatly reduce the welding difficulty of the spherical reactor.
