Description
Technical field
The utility model is related to field of welding material, and weldering medicine core is protected more particularly to a kind of flat easy welding gas
Welding wire.
Background technology
It needs to use welding wire during welding, gas protective flux-cored wire purposes is very extensive, it is to utilize protective gas
Barrier propterty is promoted in weld, improves welding effect, while reduces welding difficulty, ensures welding precision.But existing gas is protected
Flux-cored wire is protected due in problem present on structure, such as：Cross section is circle, not only places unstable, and intensity and tough
Property is poor；Solder flux does not have safeguard measure, easily makes moist and loses due effect, and welding quality has a great impact；Welding wire table
The thin steel strip exposure in face in air, contacts, easy oxidation and rusting with moisture, oxygen；Gas protective flux-cored wire and protection
Gas interface is small, causes welding effect bad；Electric arc is unstable, and molten bath poor fluidity, metallurgical reaction is insufficient, welding point
It is of low quality.Therefore, the improvement of flux-cored wire is imperative with innovating.
Utility model content
For the above situation, to overcome the defect of the prior art, the purpose of the utility model is just to provide a kind of flat
Easy welding gas protection weldering flux-cored wire, can effectively solve to place unstable, intensity and poor toughness, solder flux moisture-sensitive, surface
Oxidizable, flux-cored wire and protective gas contact surface are small, and gas shield effect is poor, and electric arc is unstable, molten bath poor fluidity, metallurgical
React the problem of insufficient.
The technical solution that the utility model solves is that including strip medicine core, medicine core is wrapped with copper mesh, and copper mesh is coated with
Damp-proof layer, damp-proof layer are coated with sheetmetal layer, have enamel-cover anti oxidation layer outside sheetmetal layer, uniformly distributed ventilation hole is provided on sheetmetal layer,
U-type groove is provided in sheetmetal layer peripheral outer wall, the through hole to match with U-type groove is provided on enamel-cover anti oxidation layer, forms U-shaped ventilation
Road.
The utility model is simple and reasonable, has the work(for ensureing that core solder flux is dry, preventing sheetmetal surface moisture from getting rusty
Can, increase effectively the contact area of welding wire and protective gas, arc burning is stablized during welding, and weld metal metallurgical reaction fills
Point, ensure welding quality, be the innovation on flux-cored wire.
Description of the drawings
Fig. 1 is the cross-sectional structure front view of the utility model strip flux-cored wire.
Specific embodiment
It elaborates below in conjunction with attached drawing to specific embodiment of the present utility model.
As shown in Figure 1, the utility model includes strip medicine core 1, and medicine core 1 is wrapped with copper mesh 2, and copper mesh 2 is coated with anti-
Damp layer 3, damp-proof layer 3 are coated with sheetmetal layer 4, have enamel-cover anti oxidation layer 5 outside sheetmetal layer 4, uniformly distributed ventilation is provided on sheetmetal layer 4
Hole 6 is provided with U-type groove in 4 peripheral outer wall of sheetmetal layer, and the through hole to match with U-type groove is provided on enamel-cover anti oxidation layer 5, forms U-shaped
Ventilating duct 7.
In order to ensure using effect, the cross section of the flux-cored wire is flat, is easy to place, and adds welding wire
Intensity and toughness.
The damp-proof layer 3 is thermal grease layer, and damp-proof layer 3 ensure that the drying of drug core layer 1, it is ensured that welding process
Stability.
The grid of the copper mesh 2 is less than the grain size of the heat-conducting silicone grease particle of damp-proof layer 3, and copper conducts electricity very well, and welds
When arc burning stablize, copper makes the increase of molten bath mobility after copper mesh 2 melts, and weld metal metallurgical reaction is abundant, welds matter
Amount is high.
The sheetmetal 4 is surrounded by the ventilation hole 6 of four or more and the U-shaped air passage 7 of four or more, increases welding wire with protecting
The contact area of gas is protected, improves protecting effect.
4 outside of sheetmetal is wrapped in enamel-cover anti oxidation layer 5, prevents sheetmetal surface wetting from getting rusty after aoxidizing, welding wire uses
It works well.
It is noted that above-mentioned, provide is only embodiment, be for illustrating specific embodiment of the present utility model, and
It is not intended to limitation the scope of protection of the utility model, therefore, all any Spirit Essences and principle without departing from the utility model
Lower made change, modification, replacement, combination, simplification, are included within the scope of protection of the utility model.
The utility model compared with prior art, has the following advantages：
1）The cross section profile of flux-cored wire is flat, is easy to place, and adds intensity and toughness；
2）Contain damp-proof layer inside flux-cored wire, ensure that the drying of core solder flux；
3）Outside is equipped with enamel-cover anti oxidation layer, prevents surface moisture from getting rusty, welding wire using effect is good；
4）Ventilation hole and air passage are equipped in sheetmetal, increases the contact area of welding wire and protective gas, improves welding effect
Fruit；
5）The drug core layer of flux-cored wire and moisture-proof interlayer are equipped with copper mesh, the good conductivity of copper, and arc burning is stablized during welding,
Copper makes molten bath mobility increase after copper mesh fusing, and weld metal metallurgical reaction is abundant, and welding quality is high.
