焊接变形的理论核算与应用

The Theoretical Accounting & Application Of Welding Deformation

在实际生产过程中,构件焊接后会在内部产生焊接残余应力,同时产生焊接变形,对构件的正常使用产生不利影响。文章通过对焊接变形产生机理进行分析,并对构件的焊接变形进行理论核算,为正确控制和利用焊接变形提供了理论依据。

In the procedure of practical manufacturing,welding remaining stress,and also welding deformation will appear inside the component after welding.This will be harmful to the normal use.By the analysis of the principle to which it gives birth,this article gives the theoretical accounting to the component’s deformation after welding,which gives the theoretical gist for the correct control and utilization the welding deformation.
