横向收缩变形：构件焊后在垂直焊缝方向上发生的收缩。
Transverse/cross/lateral contraction deformation:The component contracts in the upright direction of weld after weiding.
随着激光单脉冲能量输入的增加，焊接件的横向收缩变形和失稳变形变大。
With the single-pulse laser energy input increasing, the transverse shrinkage and buckling distortion are improved.
气冷的方法，可以使试样散热更快，达到控制温度的目的，同时也可以减小焊接残余应力和焊接横向收缩变形。
Wind cooling accelerated elimination of heat dissipation, and controlled temperature which made welding transverse contraction deformation and the residual stresses decrease.
