近年来,随着化工工业和石油化学工业的发展,压力容器新工作介质的出现,需要有更多、更好的压力容器钢材来满足市场的需求,承受高压和强腐蚀,铝合金就是近年来发展比较迅速的压力容器材料。楚雄技师学院(以下简称学院)与企业在校企合作中,承揽了一批焊接5154铝镁合金压力容器及部分管道的生产任务,为减小焊接应力和变形,提高工作效率,学院采用手工钨极氩弧焊,交流弧焊电源。经过一段时间的焊接实践,把焊好的铝合金焊缝X
In recent years, with the development of the chemical industry and the petrochemical industry, the emergence of new working media for pressure vessels requires more and better pressure vessel steel to meet the needs of the market, withstand high pressures and strong corrosion, and aluminum alloys have been developed in recent years The development of relatively rapid pressure vessel materials. Chuxiong Technician College (hereinafter referred to as the College) and enterprises in the school-enterprise cooperation, the contract number 5154 aluminum-magnesium alloy pressure vessel and part of the pipeline production tasks, in order to reduce welding stress and deformation, improve work efficiency, the college uses hand-tungsten Argon arc welding, AC arc welding power supply. After a period of welding practice, the welded aluminum alloy weld X
