Abstract

The invention relates to the technical field of welding devices, in particular to an auxiliary welding device, welding equipment and a welding method. According to the auxiliary welding device, a guide support assembly is connected with a synchronous beam, and two sets of flange pressing components are arranged symmetrically on both sides of the guide support assembly and are separately connectedwith the synchronous beam so that welding channels can be formed on the inner and / or outer sides of the two sets of flange pressing components to ensure that each welding energy beam can move synchronously in the corresponding welding channel and form symmetrical welds on each flange when the plurality of welding energy beams are emitted in simultaneously. The auxiliary welding device can achievesimultaneous welding of both flanges of components by one-time running. The welding seams obtained by the welding equipment of the auxiliary device are symmetrical, beautiful compared with the prior art, and the flange welding deformation is small, so that the auxiliary welding device improves the welding efficiency and welding quality significantly.

Description

technical field [0001] The invention relates to the technical field of welding equipment, in particular to a welding auxiliary device, welding equipment and a welding method. Background technique [0002] Due to its outstanding advantages such as fast welding speed, good processing flexibility, and small deformation after welding, laser welding has become one of the key welding methods in the welding process of rail vehicle side wall panels. With the rapid development and popularization of high-power fiber lasers in recent years, the laser welding manufacturing technology of rail vehicle side wall panels has been greatly developed. [0003] In the side wall panel structure, the π-shaped sheet metal member is a common member form. The two sides of the component are respectively provided with flanging, and the component is welded to the inner side of the wall plate through the flanging, so as to improve the strength of the overall component of the wall plate. At present, in ...
