Abstract

In view of the structural characteristics of the slender stainless steel cylinder product and the difficulties of the welding process of a large experimental device

the welding method and welding process parameters are optimized

and the splitting and processing optimization scheme of the slender stainless steel cylinder welding product are proposed. A UY-shaped welding joint with snap position is designed. Using the lathe chuck

center frame and tail seat as the clamp fixing fixture for the slender stainless steel cylinder docking and welding

it effectively solves the difficulties of the slender stainless steel cylinder welding that are difficult to assemble

fix

difficult to change welding orientation and easy to skew. A simulation model of the slender stainless steel cylinder docking welding is established

which simulates the bending deformation law and welding shrinkage in the welding process

which provides an important theoretical basis for welding deformation control

welding pre-residual processing allowance

and welding bending correction. A real-time welding compensation technology based on distal cylindrical beating is proposed to organically fuse welding

detection and bending correction

which greatly improves the machining efficiency. Practical application shows that the real-time welding compensation technology can better control the axial bending deformation of slender stainless steel cylinder.
