Abstract
A special welding wire for electric-arc welding is characterized in that a welding wire layer is arranged on the inner layer, a film forming protection layer is arranged on the outer layer, each welding wire of the welding wire layer is spiral, and the film forming protection layer utilizes rosin. Welding flux can be guaranteed to be coated on the spiral welding wires uniformly and tightly, thereby being favorable for playing advantages of automatic on-line coating pressing welding processes.
Description
Technical field
The utility model relates to a kind of welding wire, refers to a kind of arc welding special welding wire especially.Belong to welding technology field.
Background technology
The arc welding special welding wire that extensively adopts is cylindrical at present, and smooth surface is smooth, and this class welding wire can be used for manual electric arc welding, automatic submerged arc welding, CO
2Gas shielded arc welding and argon arc welding etc., and, then can not satisfy its requirement to welding wire for the online coating compacting of a kind of new welding manner----welding automatically.The compacting of online coating defend automatically connect be with the solder flux pressure dressing after on the welding wire, welding requires solder flux securely to be wrapped in welding wire surface immediately, comes off if any solder flux, can have a strong impact on the welding quality.The smooth welding wire of this smooth surface is unfavorable for that the solder flux compacting is coated on the welding wire.
Summary of the invention
At the shortcoming of prior art, the purpose of this utility model is to provide a kind of online coating compacting automatic arc welding special welding wire that is exclusively used in online coating compacting automatic soldering technique.
The technical scheme that its technical problem that solves the utility model adopts is: described welding wire is a helicoidal structure, and there is the film forming protective layer on its surface.
The beneficial effects of the utility model are: can guarantee solder flux evenly pressure dressing securely on the spirality welding wire, help bringing into play the superiority of online coating compacting automatic soldering technique.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a vertical structure schematic diagram of the present utility model.
Fig. 2 is a transversary schematic diagram of the present utility model.
Among the figure: 1 is that welding wire layer, 2 is the film forming protective layer.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Referring to accompanying drawing, the utility model is characterised in that: internal layer is a welding wire layer 1, and skin is a film forming protective layer 2, and the welding wire of described welding wire layer 1 is a helicoidal structure, and described film forming protective layer 2 can be a rosin.
