摘　　要：我公司采用PMIG焊机焊接5052、6061铝合金时,在没有进行无损探伤的情况下,外观检查没有焊接缺陷,但在产品的试运行过程中,频繁受力部位经常出现焊缝根部整个撕裂的现象,直接影响产品的质量,从焊机和材料焊接特性分析产生焊缝根部撕裂的原因,优化工艺,归纳总结避免产生焊缝根部撕裂的控制措施。When the company uses PMIG welding machine to weld 5052,6061 aluminum alloy,there is no welding defect in appearance inspection without non-destructive testing.However,during the trial operation of the product,the root of the weld often appears on the frequently stressed parts.The phenomenon of tearing directly aff ects the quality of the product.From the welding characteristics of the welder and the material,the reasons for the root tear of the weld are analyzed,the process is optimized,and the control measures to avoid the root tear of the weld are summarized.
