How to minimize deformation after machining and welding in thin-walled cylindrical containers
Thread Content
The material is 2mm thick 304 steel plate, used for atmospheric pressure rectangular vessels; it suffers significant deformation after machining (in areas with numerous holes) and welding. I would appreciate your advice.
The control of welding deformation in thin-walled stainless steel relies on three main measures: first is the control of wire energy; TIG welding with low wire energy can be used, and self-fluxing welding may also be considered. The second is forced deformation, which involves using fixtures to clamp the areas on both sides of the weld in order to control wave-like deformation. Third are the cooling measures: the welds are cooled by forced water cooling, and copper fixtures can be used, with cooling water circulated inside to achieve forced cooling.
