Technical field
The utility model is related to field of welding material, particularly a kind of multiple protective stable type flux-cored wire.
Background technology
Flux-cored wire is with welding synthesis is at low cost, welding quality is preferable, automatic welding can be achieved, welding efficiency is general
The advantages that leading to 3 ~ 4 times of manual welding, it is subject to the extensive favor of people.But common flux-cored wire is to coat medicinal powder by steel band,
The circular welding wire formed through rolling, drawing easily rolls, and placement is unstable, inconvenient for use；The intensity and toughness of welding wire are low, are storing up
Deposit and use during frangibility, cause welding when weldquality decline；During storage, steel strip surface is easily moist raw
Rust is welded in use, Wire Performance is poor；Molten bath poor fluidity when flux-cored wire welds, metallurgical reaction is insufficient, influences weld seam
Final performance.Therefore, flux-cored wire improvement and innovation be a technical problem to be solved urgently.
Utility model content
For the above situation, to solve the defect of the prior art, the purpose of this utility model is to provide a kind of multiple protective
Stable type flux-cored wire can be efficiently solved existing for existing flux-cored wire：1. place it is unstable, it is inconvenient for use；2. intensity and
Toughness is low；3. easy oxidation corrosion during storage, Wire Performance is poor during welding；4. molten bath poor fluidity during welding, metallurgical reaction is not
Fully, the problem of poor welding quality.
The technical solution that the utility model solves is that, including strip medicine core, strip medicine core is wrapped with steel belt layer, steel belt layer
It is equipped with the first protective layer, the second protective layer, the 3rd protective layer successively outside, first protective layer is copper plate, and second protects
For layer for anodic oxidation protective layer, the 3rd protective layer is olive oil reservoir, and the cross section of flux-cored wire is dumb-bell shape, the horizontal stroke of strip medicine core
Section is symmetrical two circles.
The utility model structure novel, shelf-stability is good, the intensity and toughness of welding wire is increased effectively, equipped with multiple guarantor
Shield has the characteristics that improve welding wire intensity, prevents oxidation corrosion, improves Wire Performance, copper after copper plate melts during welding
The mobility in molten bath is enhanced, makes weld metal metallurgical reaction abundant, quality of weld joint is high, is 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 strip medicine core 1 is wrapped with steel belt layer 2, outside steel belt layer 2
The first protective layer 3, the second protective layer 4, the 3rd protective layer 5 are equipped with successively, and first protective layer 3 is copper plate, and second protects
Sheath 4 is anodic oxidation protective layer, and the 3rd protective layer 5 is olive oil reservoir, and the cross section of flux-cored wire is dumb-bell shape, strip medicine core
Cross section be symmetrical two circles.
The dumb-bell shape that 2 cross section of steel belt layer connects and composes for the identical tangent arc of radius.
The thickness of the first protective layer copper plate is 100~500 μm.
Second protective layer is less than the composite bed that zinc, the magnesium metal material of copper are formed by normal potential.
In said structure, the outer profile of the steel belt layer connects and composes for the identical tangent arc of radius, avoids
The problems such as welding wire easily rolls, and the intensity and toughness of welding wire can be effectively improved.
First protective layer is copper plate, and thickness is 100 ~ 500 μm, and copper plate not only has protective action, but also
The intensity and toughness of welding wire can be effectively improved, copper enhances the mobility in molten bath after copper plate fusing during welding.
Second protective layer is anodic oxidation protective layer, by normal potential less than metal materials such as zinc, the magnesium of copper
Or its alloy is combined, and can play better protective effect.
3rd protective layer is olive oil reservoir, this layer can completely cut off the second protective layer and moisture in air, oxygen etc.
The effect of moisture-proof antirust is played in contact, while olive oil lamella plays lubricating action, improves Wire Performance during welding.
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.
From the above, it is seen that the utility model structure novel, shelf-stability is good, increase effectively welding wire intensity and
Toughness equipped with multiple protective, has the characteristics that improve welding wire intensity, prevents oxidation corrosion, improves Wire Performance, copper facing during welding
Copper enhances the mobility in molten bath after layer fusing, makes weld metal metallurgical reaction abundant, and quality of weld joint is high, and existing
Technology is compared, and has advantageous effects following prominent：
1st, welding wire structure novel, shelf-stability is good, increases effectively the intensity and toughness of welding wire.
2nd, equipped with copper plate, in addition to protective action, the intensity and toughness of welding wire can also be improved.
3rd, equipped with anodic oxidation protective layer and olive oil reservoir, there is multiple-protection effect, prevent from oxidation corrosion and improve to send
Silk performance.
When the 4th, welding after copper plate fusing, copper enhances the mobility in molten bath, makes weld metal metallurgical reaction abundant,
Quality of weld joint is high, is the innovation on flux-cored wire.
