Water-cooling welding torch

Abstract

The invention relates to a water-cooling welding torch comprising a burner copper head, an external water division pipe connected with an external pipe which are both connected with the burner copperhead, a conductive seat copper head, and an internal liner pipe and an internal water division pipe which are connected with the conductive seat copper head, wherein at least two water injection passages are arranged between the internal liner pipe and the internal water division pipe and communicated with each other at the position of the conductive seat copper head; and at least two water injection passages are arranged between the external pipe and the external water division pipe and communicated with each other at the position of the burner copper head. Through the design, two water circulation passages are formed on the torch head and the torch body, wherein the inner liner pipe, the inner water division pipe and the conductive seat copper head form the first water circulation passage to reduce the temperature and dissipate the heat of the torch body and the torch head; and the external pipe, the external water division pipe and the burner copper head form the second water circulation passage to further reduce the temperature and dissipate the heat of the torch body and the torch head. Through the two water circulation passages, the welding torch can keep the temperatures ofthe torch head, the torch body and the welding stick in the torch body within the controlled range and ensure the working quality of the welding torch.

Description

technical field [0001] The invention belongs to the field of gas shielded welding equipment, and in particular relates to a water-cooled welding torch capable of water-cooling both the torch body and the copper head. Background technique [0002] As an important welding form, gas shielded welding has the advantages of fast welding speed, small molten pool, narrow heat-affected zone, and small deformation of the weldment after welding; the welding process is easy to operate, and there is no or little slag. It basically does not need to clean the slag, and has a wide range of applications in the industrial field. The welding torch is relatively close to the welding pool, and a large amount of heat energy generated during the welding process will heat the copper tip of the burner and the torch body. On the one hand, high temperature will affect the normal welding of the operator, and more importantly, the overheating of the copper head will seriously affect its life, and the h...

AI Technical Summary

Problems solved by technology

On the one hand, high temperature will affect the normal welding of the operator, and more importantly, the overheating of the copper head will seriously affect its life, and the heat energy of the torch body cannot be dissipated in time, which will cause thermal bending deformation of the welding wire passing through the torch body. In turn, it affects the normal progress of wire feeding, resulting in poor wire feeding, which is not conducive to welding
