Fabricating method and device for welding wire with exterior coated flux

Abstract

The invention discloses a fabricating method for a welding wire with exterior coated flux, relates to the technical field of tin brass welding wires and solves the technical problems that when existing tin brass welding wires are welded with copper gas welding flux, many hours are spent, the welding efficiency is decreased, and meanwhile, high-frequency welding can not be directly performed, so that requirements of many clients at home and abroad can be met. The method includes the following steps that a, raw materials containing copper, zinc, tin and silicon are smelted, extruded, and pulled and cut to form the welding wire; b, the copper gas welding flux is smelted so that the copper gas welding flux is suitable for being coated on the surface of the welding wire; c, the copper gas welding flux which is suitable for being coated is uniformly coated on the surface of the welding wire in a proper thickness; d, the welding wire coated with the copper gas welding flux is dried. According to the fabricating method and a fabricating device for the welding wire with the exterior coated flux, the efficiency can be greatly increased, welding costs are reduced, the welding is convenient, and the stability of welding property is improved.

Description

Technical field [0001] The invention relates to the technical field of tin brass welding wire. Background technique [0002] Tin brass welding wire is mainly used for brazing copper and copper alloys. It is widely used in valves, cutting tools, auto parts, hydraulic parts and many other industries. It is mainly used in the form of oxygen acetylene welding with copper gas welding flux (CJ301). The new technology has been introduced. Most of the traditional tin brass welding wire is used with copper gas welding flux CJ301 for gas-oxygen welding. It is necessary for the welder to have a good understanding of the characteristics of the wire and flux, and the proper combination of the two can achieve the ideal welding effect. At the same time, due to the need to adjust the flux and apply the flux during the welding process, a lot of man-hours are consumed, which reduces the welding efficiency, and at the same time, it is impossible to directly perform high-frequency welding. All these...

[0002] Tin brass welding wire is mainly used for brazing copper and copper alloys. It is widely used in valves, cutting tools, auto parts, hydraulic parts and many other industries. It is mainly used in the form of oxygen acetylene welding with copper gas welding flux (CJ301). The introduction of new technology, the traditional tin-brass welding wire is mostly used with copper gas welding flux CJ301 for gas-oxygen welding, which requires the welder to have a good understanding of the characteristics of the welding wire and flux, and the proper cooperation of the two can achieve the ideal welding effect , At the same time, due to the need to debug flux and apply flux during the welding process, it consumes a lot of man-hours, which reduces the welding efficiency, and at the same time cannot directly perform high-frequency welding. All these cannot meet the requirements of many customers at home and abroad.
