Description
Technical field
This utility model relates to welding wire technology field, especially a kind of high-fire-resistance gas protecting welding wire.
Background technology
Existing gas protecting welding wire is mostly single inner core, and this cannot be suitable at some special occasions；And it is existing
Gas protecting welding wire can produce a large amount of smog during welding, not only has injury to human body, and resistance to corrosion is poor.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, it is provided that a kind of high-fire-resistance gas
Body protection welding wire.
This utility model solves its technical problem and be the technical scheme is that a kind of high-fire-resistance gas protecting welding wire,
Including steel belt layer and core wire, core wire is positioned at steel belt layer, is provided with drug core layer between steel belt layer and core wire, and core wire includes some welderings
Silk, welding wire cross section is equilateral triangle；Described steel belt layer outer surface is provided with fluxing and fire-retarding insulating barrier, the thickness of fluxing and fire-retarding insulating barrier
Degree is 0.18～0.22 μm.
Further, described steel belt layer outer surface is integrally formed with two for anti-skidding raised line, and raised line is about core wire
Centrosymmetry is arranged.
Further, described raised line height is steel belt layer thickness 2/3rds.
The beneficial effects of the utility model are: this utility model simple in construction, reasonable in design, easy and simple to handle, can not only
It is applicable to some special occasions；And smog can be reduced when welding, there is preferable corrosion resistance；Increase on steel belt layer surface
Add fluxing and fire-retarding insulating barrier, improve the fire resistance of welding wire.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
1. steel belt layer in figure, 2. drug core layer, 3. core wire, 4. welding wire, 5. fluxing and fire-retarding insulating barrier, 6. raised line.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is further described.These accompanying drawings are the schematic diagram of simplification only to show
Meaning mode illustrates basic structure of the present utility model, and therefore it only shows the composition relevant with this utility model.
High-fire-resistance gas protecting welding wire as shown in Figure 1, including steel belt layer 1 and core wire 3, core wire 3 is positioned at steel belt layer 1
In, between steel belt layer 1 and core wire 3, it being provided with drug core layer 2, core wire 3 includes that some welding wires 4, welding wire 4 cross section are equilateral triangle；
Steel belt layer 1 outer surface is provided with fluxing and fire-retarding insulating barrier 5, and the thickness of fluxing and fire-retarding insulating barrier 5 is 0.22 μm.
Steel belt layer 1 outer surface is integrally formed with two for anti-skidding raised line 6, and raised line 6 sets about core wire 3 centrosymmetry
Put；Raised line 6 height is 2/3rds of steel belt layer 1 thickness.
Above-mentioned embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with this skill
The personage of art will appreciate that content of the present utility model and is carried out, and can not limit protection model of the present utility model with this
Enclose, all equivalence changes made according to this utility model spirit or modification, all should contain at protection model of the present utility model
In enclosing.
