Embodiment Construction

[0012] In order to enable those skilled in the art to better understand the solution of the present invention, and to make the above-mentioned purpose, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings of the embodiments.

[0013] Such as figure 2 As shown, a flux-cored welding wire according to the present invention includes a steel skin 1 and a core flux 2 wrapped by the steel skin 1; the cross section formed by the steel skin 1 wrapped by the core flux 2 is a "plum blossom" shape, wherein, The outer steel skin 1 is divided equally, and the two ends of each segment of the equally divided steel skin extend toward the center of the section to form petals 3 of a "plum blossom" structure, and the petals 3 are in close contact with the petals 3 to form a "plum blossom" shape. The welding wire with "plum blossom" cross-s...

Abstract

The invention relates to the field of welding material, in particular to a flux-cored wire. The flux-cored wire comprises sheet iron and core flux packaged by the sheet iron; the section formed by using the sheet iron to package the core flux is plum blossom-shaped, wherein the outer sheet iron is divided equally, two ends of each section of the equally divided sheet iron extend towards the center of the section to form petals of the plum blossom-shaped structure, and the petals contact closely to form the plum blossom shape. After using said structure, because the sheet iron is uniformly distributed on the whole section, the core of the flux-cored wire with the plum blossom-shaped section is conductive, the electric arc combustion is stable, the flux-cored wire melting is uniform, and the metallurgic reaction is complete.

Description

technical field [0001] The invention relates to the field of welding materials, in particular to a flux-cored welding wire. Background technique [0002] Flux-cored welding wire is another type of welding material widely used after welding rod and solid core welding wire. It is composed of metal sheath and core flux. In recent years, the amount of flux-cored welding wire in developed countries accounts for about 20% to 30% of the total welding materials, and it is still in a steady increase. The annual consumption of solid welding wire has entered a stable development stage, while the consumption of flux cored welding wire still has a lot of room for development in terms of variety, specification and consumption. [0003] Such as figure 1 As shown, under normal circumstances, the cross-sectional shape of the flux-cored wire is "O", and such a wire is called a tubular flux-cored wire. Since the core flux of the tubular flux-cored wire is non-conductive, the arc is easy to ...
