摘　　要：介绍了焊接工艺在煤矿安全生产中不可忽视的作用,就焊接变形和焊接应力的各种影响因素进行了分析,为有效控制钢结构因焊件的不均匀膨胀和收缩而造成的焊接变形提出了相应的控制措施和常用的核算方法。The factors influencing the welding stress and the welding deformation were analyzed. Because effects of welding heat source and the character of welding heat metal expands and contracts, produce stress and deformation. during weld can cause non - uniform heat, the Also presents the corresponding control measures and calculation of welding stress and the welding deformation.

关 键 词：焊接变形 焊接应力 焊接工艺 焊接
