6063硬连接与L6软连接铝母线接头TIG焊接工艺

TIG welding procedure of 6063 hard-wired connection with the L6 soft aluminum bus joints

通过分析6063硬连接与L6软连接铝母线的焊接性和焊接方法,夹钨、夹杂是TIG焊接时亟待解决的问题。根据生产需要,选用材质为6063,δ=15 mm铝厚板与28~29层L6,δ=0.5 mm铝薄板叠层进行水平固定位置的TIG焊接工艺研究,通过控制焊接工艺,寻找合适的焊接工艺参数和焊接操作手法,获得了合格的焊接接头。该接头按照相关规程的要求进行X射线检验和过电流试验,结果均符合要求。该工艺目前已用于生产中,为送变电设备的铝母线焊接提供了技术支持。

By the analysis of weldability （ff aluminum bus 6063 hard link and L6 soft connection,know the problems of tungsten inclusion and inclusion to be solved in welding.According to the production needs, we research on the TIG welding procedure with 6063 of 6=15 mm plate and 28-29 layers L6 of 8=0.5 mm sheet with level of fixed,by controlling welding procedure,finding the appropriate welding parameters and controlling welding operation technique, qualified welding joints are obtained.In accordance with the requirements of related procedures,X-ray inspection and cun＇ent test are done,the results conform to the requirements.The welding procedure is widely used in production,provides the technical support for aluminum bus bar welding of electricity transmission ＆transformation facilities equipment.
