Problems solved by technology

[0011] The systems known from the prior art include the disadvantage that such mechanical cleaning devices can only successfully clean the gas nozzles if the splash consists of solid material, especially steel or steel alloys, which means that for connecting steel or steel alloys The welding process of the workpieces is carried out such that the spatter must consist of these materials
Otherwise, the application of the usual tools known from the prior art, i.e. grinding tools, cutting tools or meta

Embodiment Construction

[0033] FIG. 1 shows a cutaway portion of a welding torch 1 , in particular the end region relevant for the welding process. The welding torch 1 includes a gas nozzle 2 , a nozzle assembly 3 and a conductive tube 4 . Other components of the welding torch 1 are omitted for clarity purposes. Furthermore, the structure and configuration of the components shown are not limited to the exemplary embodiment shown, and the solution according to the invention can be applied to any welding torch 1 or its components known from the prior art.

[0034] The gas nozzle 2 shown in FIG. 1 is made of copper or a copper alloy, and is detachably fixed to the welding torch 1 . The conductive tube 4 and nozzle assembly 3 arranged in different structures in each torch are also made of copper or copper alloy, and the conductive tube 4 is detachably connected to the nozzle assembly 3 . A description of the functional modes of these components and their tasks is omitted since these are well known in t...

Abstract

The invention relates to a gas nozzle (2) and a welding torch (1) equipped with said gas nozzle (2), a nozzle assembly (3) and a conductive tube (4), said gas nozzle (2), nozzle The component ( 3 ) and the conductive tube ( 4 ) have an artificially produced patina ( 8 ) on at least a partial area of ​​their surface for the purpose of reducing the adhesion of welding spatter. The invention also relates to a cleaning device for a welding torch (1) having a brush with bristles. These bristles are made of a very soft elastic material, preferably plastic, and abrasive particles are embedded in said bristles.

Description

technical field [0001] The present invention relates to a gas nozzle for a welding torch made of copper or a copper alloy, and a welding torch comprising a gas nozzle, a nozzle assembly and a conductive tube, wherein the gas nozzle and / or the nozzle assembly and / or the conductive tube are made of copper or copper Alloy. [0002] The invention also relates to a cleaning device for a welding torch, in particular its gas nozzle, comprising a brush provided with bristles for cleaning welding spatter of the welding torch. Background technique [0003] During the welding process, the welding torch is contaminated by molten metal spatter. The metal spatter deposits on the outer surface of the housing of the gas nozzle of the welding torch and even in the gas nozzle, where it solidifies. As a result, the shielding gas flow through the gas nozzle is disturbed by deposited metal spatter, so that ambient air can also reach the welding point, thereby adversely affecting the welding pr...
