Analysis and Optimization of Welding Deformation on Vehicle Exhaust Pipe Flange
Journal Title: Automobile Technology & Material - Year 2024, Vol 39, Issue 2
Abstract
When the exhaust pipe is welded with the flange, the welding deformation of the flange affects the tightness of the exhaust pipe assembly. In order to avoid excessive welding deformation of flange during manufacturing,the FEA model was established with the moving Gaussian heat source to simulate flange welding process. After analyzing and comparing the temperature field, stress and strain results of flanges under different constraint conditions and different welding parameters, the solution that can effectively reduce the welding deformation of flanges in the production and manufacturing of exhaust pipes was determined. This paper proposed suggestions of welding electric current, welding speed and heat source radius, which provided theoretical basis for the optimization of welding process of exhaust pipe flange.
