Description

Technical Field

[0001] The invention relates to the technical field of stainless steel workpieces, and in particular to a welding tool and a welding method for a thin-walled stainless steel workpiece. Background Art

[0002] The half shell of the irradiation monitoring tube is a 304 stainless steel sheet with a thickness of only 0.8mm. The stainless steel sheet has good ductility, especially the thin stainless steel sheet has large welding deformation and is difficult to weld. In order to ensure that the size of the half shell after welding can meet the functional requirements of the equipment, after the half shell is bent, the half shell is positioned and aligned using a clamp-type rigid fixed welding tooling, so as to ensure that the stainless steel sheet is not scrapped due to welding deformation. After welding is completed, the workpiece is allowed to cool naturally or slowly cooled using a cooling device to prevent deformation caused by thermal stress. However, some existing structures have poor heat dissipation effects. Uneven cooling may cause changes in the internal organizational structure of the workpiece, thereby affecting its hardness and mechanical properties. Rapid cooling or uneven cooling may cause thermal stress inside the workpiece. This stress may exceed the yield strength of the material and cause cracks in the workpiece. In addition, gaps are likely to exist in the heat dissipation structure when it contacts the stainless steel workpiece at the workplace, resulting in reduced heat dissipation effects.
