提出了焊接过程中产生裂纹的控制方法及对焊后变形的矫正方法。
Controlling for the variables related, preventing the crriage from cracking during welding and correcting distortion for it after welding are discussed, too.
研究表明，用基于固有应变的弹性板单元有限元法对大型焊接结构的焊后变形预测是可以实现的。
The results indicate that the FKM based on the inherent strain can predict the deformation of the large welding fabrication.
而三种工艺参数的焊后变形最大值均位于大接管左侧的焊缝处，沿左侧焊缝向容器底部方向变形逐渐减小，在接近容器底部变形又开始增大。
The MAX deformation lie to left side of big pipe, and the deformation get smaller removed from left side to container bottom, as close to the bottom, the deformation began to harder.
