Embodiment Construction

[0018] A high-frequency welding method of the present invention will be described in further detail below with reference to the accompanying drawings.

[0019] Such as figure 1 , figure 2 As shown, a kind of high-frequency welding method of the present invention is used for the welding of radiator copper pipe 20 and joint 10 (certainly can be applied to the welding connection of other workpieces), and its step comprises: first at the connection end 11 of joint 10 An annular groove 12 is opened on the outer wall of the joint, and the outer diameter of the connecting end 11 is basically the same as the inner diameter of the copper pipe 20, so that the joint 10 can be inserted into the copper pipe 20 and tightly connected with the copper pipe 20 as a whole. Then, solder is provided on the connection end 11 of the joint 10 , that is, a welding wire 30 is wound in the groove 12 , and flux is coated on the outer wall of the connection end 11 (not shown). Then, the soldered joint ...

Abstract

A high-frequency weld method for welding copper pipe with jointer includes such steps as making slots on the external surface of jointer, winding the welding wire in the slot, coating flux, inserting part of jointer in said copper pipe, fixing said copper pipe by fixture, and high-frequency heating.

Description

technical field [0001] The invention relates to a processing method of a radiator, in particular to a processing method for connecting a radiator distribution copper pipe and a joint. Background technique [0002] With the continuous development of science and technology, the welding requirements for copper pipes (such as the connection between the distribution copper pipes of radiators and the connection joints) in industrial production are getting higher and higher, especially to ensure that there is no air leakage in the welded copper pipes. In order to avoid water leakage, the traditional processing method adopts manual brazing. This kind of production process has low production efficiency, unstable welding quality, prone to unqualified products caused by human factors, high production cost, and high rework rate after the product is tested. Moreover, the labor intensity of workers is also relatively high, which cannot meet the needs of modern mass production. Contents...
