Research on Welding Deformation Control of High Temperature Alloy Thin-walled Cylinder
It was conducted that the research on welding deformation control of circumferential welds of high tempera-ture alloy thin-walled cylindrical Inconel 718 thin-walled cylinder in order to solve welding problems of an aero-engine.By analyzing the reasons for welding deformation of thin-walled cylinders,we adopted the reasonable joint design,the welding fixture design,optimized welding process,post weld heat treatment,and heat treatment deformation prevention tooling,etc.,the product weld line quality met the Class I requirements and the weld roundness deformation was controlled within 0.2 mm.The welding deformation of high temperature alloy thin-walled cylinder was well controlled,and the excellent welding line was obtained,which passed the verification.It provided technical support for excellent welds of alloy thin-walled cylinder products.
