摘 要：Welding with trail peening(WTP) is applied in T1 thin copper plate to reduce the residual stress and distortion firstly,which is the very trouble in copper welding.The main principle for this new technology was presented.To make a complete comparison,both experiments and numerical simulations of thin copper plate were carried out under WTP as well as conventional welding(CW).The results confirm that WTP can reduce longitudinal residual stress in welding joint greatly.The peak value of flexure distortion decreases from 30mm under CW to only 9mm by WTP,that is to say,only 30% of CW.
