Abstract
The invention relates to various welding production requirement field, in particular to a welding wire used for tungsten electrode argon arc welding (TIG welding). A welding wire used for red-copper tungsten electrode argon arc welding with flux drug layer comprises a welding core; the surface of the polished welding wire is pressed and coated with flux; the welding wire and the flux are bonded together by acrylic resin. The flux in liquid state has extremely strong film-removing capability which can rapidly react copper oxide into sinter which floats on the surface of a melting pool, reduces surface tension, improves lubrication performance, improves welding capability, thus obtaining excellent welding joint.
Description
Technical field
The present invention relates to the various fields that need welding to produce, be used for the welding wire of argon tungsten-arc welding (TIG weldering).
Background technology
The welding wire of red copper argon tungsten-arc welding at present, (TIG weldering) all is a bare wire.In order to guarantee the quality of weld seam, welding wire adopts the deoxidized cooper that adds a small amount of Si (＜0.5%), Mn (＜0.5%), P (＜0.15%), Ti deoxidant elements such as (＜0.5%), also can add Sn (＜1.0%) in order to improve flowability.But this class bare wire is when welding thick slightly sheet material, because after needing to improve preheat temperature (＞400 ℃), the mother metal surface oxidation is serious, causes the seam poor performance, still occurs pore sometimes, is difficult to guarantee welding quality.
Summary of the invention
The present invention is intended to address the above problem, and a kind of red copper argon tungsten-arc welding welding wire that has solder flux coating layer is provided, need not very high preheat temperature in welding procedure, and the seam performance is good, does not produce pore.
The present invention is achieved in that a kind of red copper argon tungsten-arc welding welding wire that has solder flux coating layer, comprises core wire, scribbles one deck solder flux in its core wire surface pressure, and is bonding with acrylic resin between core wire and the solder flux.
It consists of 40～60% H described solder flux

Described welding flux layer thickness is 0.08～0.12mm.
Described core wire is the Si that contains less than 0.5%, the Mn less than＜0.5% and less than＜1.0% Sn deoxidized cooper.
The weld seam tensile strength of described welding wire is 200N/mm2; Percentage elongation is 30%; Its conductance is 15-20m/ Ω mm2; Hardness is 60HB.
Welding wire of the present invention is when being used for copper argon tungsten-arc welding welding; because under the Combined Protection effect of argon gas and coating solder flux; solder flux has very strong striping ability under liquid state, can be the cupric oxide reaction slag promptly, floats on weld pool surface; reduce surface tension; improve wettability, the good fluidity of weld metal improves the seam ability; do not produce pore, thereby can obtain good welding point.
