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
The present invention relates to field of welding material, particularly a kind of flux-cored wire.
Background technology
Flux-cored wire is the another class welding material of extensive use after welding rod, solid core welding wire, and it is made up of metal sheath and core solder flux two parts.The consumption of developed country's flux-cored wire accounted for 20% ~ 30% of welding material total amount in recent years, and be still in the stage that grows steadily, in the large class welding material of welding rod, solid core welding wire, flux-cored wire 3, welding rod Year's consumption is in downward trend year by year, solid core welding wire Year's consumption enters the steady development stage, and no matter flux-cored wire is in kind, specification or still has very large development space in each side such as consumptions.
As shown in Figure 1, the cross sectional shape of flux-cored wire is " O " shape under normal circumstances, and such welding wire is called tubulose flux-cored wire.Tubulose flux-cored wire due to core solder flux non-conductive, electric arc is easy to rotate along the sheetmetal of surrounding, and arc stability is poor, have impact on the final molding of weld seam.
Summary of the invention
For above-mentioned defect of the prior art, the invention provides a kind of flux-cored wire, this flux-cored wire can make arc burning stablize, and wire melting is even, and metallurgical reaction is abundant.
A kind of flux-cored wire of the present invention, comprises the core solder flux of sheetmetal and sheetmetal parcel; The cross section that described sheetmetal parcel core solder flux is formed is " plum blossom " shape, wherein, outer field sheetmetal is halved, and each section of two ends of halved sheetmetal have extended to form the petal of " plum blossom " shape structure to kernel of section, petal and petal close contact constitute " plum blossom " shape.
Preferably, be provided with damp-proof layer between described core solder flux and sheetmetal, described damp-proof layer is thermal conductive silicon lipid layer.
Preferably, the length that each section of described sheetmetal extends to center, interface is 1/1 to three/4th of section radius.
Adopt after said structure, the welding wire of " plum blossom " tee section is evenly distributed because of sheetmetal on whole section, and wire core also can conduct electricity, so arc burning is stablized, wire melting is even, and metallurgical reaction is abundant.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the schematic diagram in traditional welding wire cross section;
Fig. 2 is structural representation of the present invention.
Detailed description of the invention
In order to make those skilled in the art person understand the present invention program better, and enable above-mentioned purpose of the present invention, feature and advantage become apparent more, below in conjunction with embodiment and embodiment accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 2, a kind of flux-cored wire of the present invention, comprises the core solder flux 2 of sheetmetal 1 and sheetmetal 1 parcel; The cross section that described sheetmetal 1 wraps up core solder flux 2 formation is " plum blossom " shape, wherein, outer field sheetmetal 1 is halved, and each section of two ends of halved sheetmetal have extended to form the petal 3 of " plum blossom " shape structure to kernel of section, and petal 3 and petal 3 close contact constitute " plum blossom " shape.The welding wire of " plum blossom " tee section is evenly distributed because of sheetmetal on whole section, and wire core also can conduct electricity, so arc burning is stablized, wire melting is even, and metallurgical reaction is abundant.
Preferably, be provided with damp-proof layer 4 between described core solder flux 2 and sheetmetal 1, described damp-proof layer 4 is thermal conductive silicon lipid layer, and damp-proof layer ensure that the drying of core solder flux 2, ensure that stability and the welding quality of welding process.
Preferably, the length that each section of described sheetmetal 1 extends to center, interface is 1/1 to three/4th of section radius.
The above; be only the specific embodiment of the present invention, protection scope of the present invention is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should define with claim is as the criterion.
