The authors consider that rational welding sequence and multi-plate skip welding method can effectively suppress the wave-type deformation of bottom welding.
Different assembly-welding sequence may result different risidual deformation, we usually take fixup by spot welding first, then take welding symmetrically.
不同的装配—焊接顺序，焊后产生不同的残余变形，一般是先点固，再进行对称焊接。

With two different tensioning schemes, the influence of the tensioning sequence on stress and deformation is calculated and the tensioning sequence is optimized.
