摘　　要：本文用全面质量管理理论分析厦工5T装载机动臂座梁焊缝开裂原因,其是由于个别工位焊工未严格按照工艺执行,部分产品存在未熔合、未焊透等焊接缺陷导致的。然后本文根据原因提出改善措施。In this paper, the cause of welding seam cracking of movable arm base beam of Xiagong 5T loader was ana-lyzed with total quality management theory, which is due to the fact that the welder in individual stations has not beenstrictly implemented in accordance with the process, and caused by welding defects such as incomplete fusion and in-complete welding in some products. Then, the improvement measures were put forward according to the reasons.
