The author points out the butt joint welding deformation of the stainless steel skin. The main cause of stainless steel skin butt joint deformation is analysised carefully. Then the important cause of the welding deformation is analyzed. The technology measures of overcoming the deformation and changing the welding assembly sequence are introduced. The final settlements are made. The technology problem over a long period of time is solved effectively. Moreover, the technology bottleneck of welding deformation is overcame, which gives the support for the usage of same products.
