Appearance-improved welding method for welded structure of resin plate and metal frames

Abstract

The invention discloses an appearance-improved welding method for a welded structure of a resin plate and metal frames. The appearance-improved welding method is characterized by comprising the following steps that S1, a weldment is prepared; S2, the weldment is polished; S3, the weldment is fixed; S4, spot welding positioning is carried out; S5, welding spots are polished, specifically, the welding spots are polished to reduce the gradient of the welding spots; S6, backing welding is carried out, specifically, backing welding is carried out along a welding path through welding equipment; S7,filling welding is carried out, specifically, filling welding is carried out on the backing welding through the welding equipment; S8, the welding surface is polished, specifically, the welding surface is polished to ensure that the welding surface is flat and smooth; S9, the resin plate is inserted, and the resin plate is inserted into a frame formed by the first metal frame, the second metal frame and the third metal frame; and S10, the steps S3 to S7 are repeated after the resin plate is inserted. According to the appearance-improved welding method for the welded structure of the resin plate and metal frames, operation is easier, welding is convenient, it can be guaranteed that the resin plate makes little contact with flames and cannot deform, the four metal frames are located on the same horizontal plane, and the appearance is more attractive.

Description

technical field [0001] The invention relates to the field of welding methods, in particular to a welding method for improving the appearance of a welding structure of a resin plate and a metal frame. Background technique [0002] With the development of economic level, refrigerators have become an indispensable electrical appliance in daily life, and many parts in refrigerators need to be connected by welding technology. The existing welding technology is relatively mature, but for a small number of refrigerator structures When welding with welding technology, it will reduce the welding effect and affect the product quality. For example, in the process of welding the resin plate and the metal frame, when the four metal frames are in contact with the middle resin plate, the flame temperature of the welding torch is high. Every time welding, The resin plate will be melted once, which may deform the resin plate. In addition, the metal frame cannot be guaranteed to be on a horiz...

[0002] With the development of economic level, refrigerators have become an indispensable electrical appliance in daily life, and many parts in refrigerators need to be connected by welding technology. The existing welding technology is relatively mature, but for a small number of refrigerator structures When welding with welding technology, it will reduce the welding effect and affect the product quality. For example, in the process of welding the resin plate and the metal frame, when the four metal frames are in contact with the middle resin plate, the flame temperature of the welding torch is high. Every time welding, The resin plate will be melted once, which may deform the resin plate. In addition, the metal frame cannot be guaranteed to be on a horizontal plane, and the appearance is ugly. Therefore, we propose a welding method for improving the appearance of the resin plate and metal frame welding structure.
