分析了焊接对构件变形的影响 ,焊接过程中材料的组织变化所带来的材料特性的改变 ,指出焊接变形的根本原因就是在冷却过程中奥氏体晶粒的不均衡长大 ,从而造成钢板的变形 ,最后为克服焊接变形提出了一些具体措施
The influence of welding on the deformation of the component was analyzed. The change of the material properties caused by the change of the structure of the material during the welding process was pointed out. The fundamental reason of the welding deformation was that the austenite grains grew unevenly during the cooling process, Of the deformation, the last to overcome the welding deformation put forward some concrete measures
