New idea to control welding residual stress and distortion with trailing impactive electromagnetic force was given. 提出了基于脉冲电磁力随焊控制焊接应力及变形新方法。
Because of non-uniform temperature distribution, at the course of welding and postweld, weldment takes on serious welding stress and deformation. 因为焊接温度场分布十分不均匀,在焊接过程中和焊后将产生相当大的焊接应力和变形。
