Residual Welding Stress - an overview ScienceDirect Topics

Welding residual stresses and distortion are always associated with each other.They are two aspects of the nonuniform transient strain caused by welding.On the other hand,buckling distortion is caused by compressive residual stresses.Thus,residual stresses need to be studied for the method of welding with intensive cooling.Residual Stress in WeldingIt is not straightforward to ensure good quality weld seams as the rapid heating and cooling over the weld area create residual stresses and change the quenching properties.Processes and Mechanisms of Welding Residual Stress and It is closely related to the metallurgical reactions,crystallization,and other phase transformations.The accurate measurement of the thermal process is a prerequisite for understanding and controlling metallurgical events,strain and stress during welding,residual stress and distortion after welding.
