Embodiment Construction

[0029] The present invention is further described in conjunction with the following examples.

[0030] Such as Figure 1-3 As shown, the present embodiment provides a welding method for air-conditioning chassis sheet metal parts, including the following steps:

[0031] (1) Welding positioning: One side of the block 1 is welded and fixed on the chassis 2 by spot welding, so that the upper end of the block 1 and the chassis 2 form a positioning welding angle 3, and a weld is formed between both sides of the block 1 and the chassis 2. side 4;

[0032] (2) The first welding fixation: through MAG welding, the positioning welding angle 3 on the upper end of the stopper 1 and the welding edge 4 away from the welding spot 5 are carried out at one time according to the fixing path 6 of the first welding; not only can the The coherent operation of the welding path, that is, one-step completion of the operation, optimizes the time for welding preparation and shutdown waiting, and at th...

Abstract

The invention relates to the technical field of welding of air conditioner sheet metal parts, in particular to a welding method for an air conditioner chassis sheet metal part. The welding method forthe air conditioner chassis sheet metal part comprises the following steps that (1) welding positioning is carried out, specifically, one side of a stop block is welded and fixed to a chassis throughspot welding, so that the upper end of the stop block and the chassis form a positioning weld fillet, and weld toes are formed between the two sides of the stop block and the chassis; (2) primary welding fixing is carried out, specifically, the positioning weld fillet at the upper end of the stop block and the weld toe far away from a welding spot are welded at a time through MAG welding; and (3)secondary welding fixing is carried out, specifically, the welding toe with the welding spot is welded through MAG welding. The welding method for the air conditioner chassis sheet metal part has theadvantages that the standardized operation of a welding process is realized, meanwhile, the problem of the quality abnormality caused by the welding variable of the welding process can be solved, andthe welding quality and the production efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of welding sheet metal parts of an air conditioner, in particular to a welding method for a sheet metal part of an air conditioner chassis. Background technique [0002] Due to the structural limitations of the sheet metal parts of the air-conditioning chassis, the notch of the bending edge needs to be completed by welding. In order to achieve the optimal cost control and achieve the goal of enterprise product production quality and production efficiency in the production process, MAG welding (carbon dioxide gas protection weld); [0003] The thickness of the sheet metal chassis material is only 2mm, and the material type is hot-dip galvanized sheet, which is a new process using the MAG welding method. As a welding method with high production efficiency, MAG welding has been widely used in the machinery manufacturing industry. The thickness of sheet metal parts is thin, and the appearance quality is extreme...
