Cold-compression welding wire machine

Abstract

The invention provides a cold press welding wire machine wherein the welding electrode will not be bonded by welding residual matter. The cold press welding wire machine comprises the welding electrode made of ceramic material which has large difference from metal wire in chemical structure, in addition, the surface of the ceramic material is smooth, thereby the welding electrode will not be bonded by welding residual matter in general case and the welding in next time will not be effected, the welding efficiency and welding quality can be improved.

Description

technical field [0001] The invention relates to a welding wire mechanism, in particular to a cold-pressed wire welding machine. Background technique [0002] Welding wire machines can generally be divided into hot-pressed wire machines and cold-pressed wire machines. [0003] The welding of the hot-press welding wire machine is to melt the welding wire or flux by heating it. In the hot state, the distance between the molecules of the welding wire and the weldment is reduced, and the molecular force makes the two "integrate". [0004] The cold-pressed welding wire machine is to apply the pressure between the welding wire and the weldment. Under high pressure, the distance between the welding wire and the weldment is reduced, and the molecular attraction is greater than the molecular repulsion. The comprehensive molecular force makes the two "bond" into one. [0005] At present, the welding electrodes of cold-pressed wire welding machines are generally made of metal materials...

AI Technical Summary

Problems solved by technology

[0005] At present, the welding electrodes of cold-pressed wire welding machines are generally made of metal materials. During the welding process, the welding electrodes are easily bonded by welding residues, which will affect the welding of the next product.
