Back face welding method and welding table for aluminum curtain wall plates

Abstract

The invention discloses a back face welding method and a welding table for aluminum curtain wall plates, and relates to the technical field of back face welding. According to the key points of the technical scheme, the back face welding method comprises the following steps that a to-be-welded first aluminum curtain wall plate is taken to be provided with a square inserting groove, a second aluminum curtain wall plate is taken, and a square inserting block is fixed; the front faces of the two aluminum curtain wall plates are downwards placed on a base, and the square inserting block and the square inserting groove are connected in an inserted mode; and welding is conducted from the back face joint of the two aluminum curtain wall plates. The welding table comprises the base, two abutting pieces and two sets of pressing devices; each set of pressing device comprises two supporting rods and two pressing plates; and a driving mechanism for driving the supporting rods to rotate is arrangedbetween each supporting rod and the corresponding abutting piece. According to the back face welding method and the welding table for the aluminum curtain wall plates, the problem that a coating is damaged by the high temperature during welding is solved, and possibility that the coating of the wall plates is damaged by the high temperature during welding is reduced. In addition, the welding tablehas the advantage that the aluminum curtain wall plates are fixed in the welding process.

Description

technical field [0001] The invention relates to the technical field of back welding, more specifically, it relates to a back welding method and a welding station for aluminum curtain wall panels. Background technique [0002] At present, the surface of aluminum curtain wall panels is treated with fluorocarbon spraying after pre-treatment such as chromization. Polyvinylidene fluoride resin for fluorocarbon coating topcoats and varnishes. Fluorocarbon coating has corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, has excellent cold and heat resistance, can resist strong ultraviolet radiation, and can maintain long-term non-fading and non-chalking. long life. [0003] For the prior art, please refer to the Chinese invention patent with the authorized announcement number CN101474732B, which discloses a welding method for side wall panels of railway vehicles, which includes stretching the side wall panels along the welding ...

AI Technical Summary

Problems solved by technology

[0004] However, during the welding process of the above-mentioned side wall panels, the weld seam is located on the front of the wall panels; since the front of the aluminum curtain wall panels is coated with fluorocarbon, the high temperature during welding will cause damage to the coating, thereby affecting the corrosion resistance of the aluminum curtain wall panels and weather resistance
