Abstract

Provided are a flux cored welding rod forming module, a preparation device and a preparation method thereof. When a flux cored welding rod forming module is used, firstly, an elongated hollow shell (1) is formed in a shell molding portion, and then welding flux (11) is injected into the hollow portion of the shell through a welding flux introducing passage (3), thereby solving the problem in the prior art that the welding flux is coated on an outer layer of an alloy tube and is adhered by an adhesive, resulting in large volume of smoke during use. The method for continuously preparing the flux cored welding rod does not produce a crease, and avoids pollution to the welding rod caused by a lubricant entering the crease when the welding rod is pulled during the later process.

Description

technical field [0001] The invention relates to the technical field of electrode forming, in particular to an electrode preparation device and an electrode preparation method. Background technique [0002] Alloy welding rods such as copper and silver are commonly used brazing materials, and are widely used in welding between metals. In the specific use of welding rods, it is often necessary to add flux (flux) to assist welding. The purpose is to eliminate metal oxidation and increase the fluidity of molten metal to achieve better welding results. [0003] In solders such as tin alloys, the flux is often directly injected into the welding wire through the shunting combined extrusion method, and then drawn into welding wires of different specifications by stretching. But the shunt combination is only suitable for metals with low deformation resistance and good welding performance. [0004] The comparative document CN103551757B discloses an aluminum-silicon alloy seamless flu...
