摘　　要：不锈钢与碳钢相比较更容易产生焊接变形,特别是在薄壁不锈钢设备制造过程中,接管与壳体角焊缝的焊接变形更为严重。该变形严重影响了接管的伸出长度,给现场配管安装带来困难,并且影响产品外观成形质量。对焊接变形产生的原因进行了分析,提出了变形控制措施及变形矫正方法,取得了良好的应用效果。Being compared with carbon steel, stainless steel is much easier to cause deformation in welding process, especially during fabrication of thin wall stainless steel equipment. Welding deformation for fillet welds between nozzle and shell is even more serious, which severely impacts the protrusion length of nozzle and bring difficulty to install installation in site. The reasons, control measures and correction method for welding deformation were analyzed in this paper.
