Abstract

The invention relates to the field of torsion beam machining, in particular to a torsion beam forming double-wire welding process. A welding seam is welded through two welding guns, the two welding guns are the first welding gun and the second welding gun respectively, the first welding gun conducts backing welding on the welding seam firstly, and then the second welding gun follows the first welding gun to conduct facing welding on the welding seam. According to the scheme, the welding effect of a torsion beam is improved.

Description

technical field [0001] The invention relates to the field of torsion beam processing, in particular to a torsion beam forming double-wire welding process. Background technique [0002] The torsion beam is a tubular structure formed by punching and bending a plate. After the plate is bent into a tubular shape, two opposite ends of the bent plate need to be welded. The current welding method adopts single-wire welding. Single-wire welding uses one welding torch to weld one weld. The heat generated during the welding process is relatively large, the heat-affected zone is relatively large, and the welding efficiency is low. Contents of the invention [0003] The invention intends to provide a torsion beam forming double-wire welding process to improve the welding effect of the torsion beam. [0004] In order to achieve the above object, the present invention adopts the following technical scheme: a torsion beam forming double-wire welding process, a welding seam is welded by ...
