AI Technical Summary
Technical Problem
Deformation of the stainless steel shell due to thermal stress during welding affects the product's appearance and sealing performance.
Method used
A deformation compensation structure is set on the side near the welding end face. The welding thermal stress is absorbed by thermal extension, and the local plastic deformation is guided into the deformation compensation structure to maintain the flatness of the steel shell.
Benefits of technology
It effectively reduces the unevenness of the steel shell side after welding, avoids warping, ensures overall flatness, and improves welding quality.

Abstract
The utility model relates to a kind of steel shell structures of resistance to welding deformation, including welding end face and the side surface being set in the both sides of the welding end face, the position of the side surface adjacent to the welding end face is equipped with deformation compensation structure, the deformation compensation structure can be heated ductile, to maintain the flatness of the steel shell.The utility model can actively absorb welding thermal stress, guide local plastic deformation into deformation compensation structure, so that the deformation compensation structure of two side surfaces is flattened, can effectively reduce the problem that steel shell side surface is not flat during welding receiving heat and cooling process, avoid uncontrollable warping at the junction of welding end face and side surface, so as to maintain the overall flatness of steel shell.
