longitudinal weld

Because the side beam is asymmetric, and the external four longitudinal weld locate four corner of longitudinal neutral axis ( X axis) of the side beam. For the groove weldment, the shrinkage of weld metal is the main factor making residual welding deformation.

由于侧梁非严格对称，且外部4条主焊缝环绕在纵向中性轴（X轴）的四个角点；焊缝金属收缩是形成焊接残余变形的主要因素。
