铝母线MIG焊焊接工艺

摘要

通过对铝母线6063的焊接性分析,气孔是焊接名铝及其合金时亟待解决的问题.根据培训需要,选用规格为φ250 mm×10 mm的铝母线管6063进行水平固定位置的MIG焊焊接工艺研究,通过控制焊接工作程序,寻找合适的焊接工艺参数和控制焊接操作手法,获得了合格的焊接接头.该接头按照相关规程的要求进行了一系列的检验和试验,结果均符合要求.该工艺目前已用于焊工培训中,为电站安装以及送变电设备的铝母线焊接提供了技术支持.%By the analysis of weldabality of aluminium bus 6063.know the problems of porosity to be soloved in welding aluminium and its alloys. According to the training needs,we start the MIG welding procedure with aluminium bus 6063 of φ250 mm×10 mm with level of fixed ,by controlling welding procedure,finding the appropriate welding parameters and controlling welding operation technique,so a qualified welded joints is given. In accordance with the requirements of related procedures,series of checking and testing are done,the results is good .The welding procedure is widely used in welder training,and take it to guide the welding of the aluminium bus in power station erection and transports power equipment.
