Description

A kind of low spatter rate ER50-6 gas shielded solid welding wire
Technical field
The invention belongs to solid welding wire technical fields, more particularly, to a kind of solid weldering of low spatter rate ER50-6 gas shielded Silk.
Background technique
The production of gas shield copper facing solid welding wire and apply it is very universal in China, with mentioning for the degree of automation The use of high especially welding robot requires welding process continuity higher and higher.And spatter can be in ignition tip and spray Adhesion is formed on pipe, the spatter being sticked on ignition tip and jet pipe under long-time welding condition can hinder normally going out for welding wire Silk and blocking is formed to welding protection air-flow, it is serious to cause spatter to fall to form slag inclusion in molten bath.Welding is reduced to fly Splash an important directions for realizing that welding for a long time is welding wire development.
It would therefore be highly desirable to the welding wire product of a novel low spatter rate be developed, to extend weldering during automatic welding The time is connect, guarantees welding quality.
Summary of the invention
In view of this, the present invention is directed to propose a kind of low spatter rate ER50-6 gas shielded solid welding wire, by chemistry at The method of sub-control realizes the control to particle transfer form and the stability of guarantee particle transfer, reaches reduction spatter rate Effect.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of low spatter rate ER50-6 gas shielded solid welding wire, the plating including steel wire matrix and coated on steel wire matrix surface Layers of copper；
The steel wire matrix includes the component of following weight percent meter: C:0.06%~0.10%；Si:0.80%~ 1.00%；Mn:1.40%~1.60%；S:0.010%~0.015%；P :≤0.015%；Mo :≤0.015%；Ni :≤ 0.015%；Cu :≤0.30%；Cr :≤0.015%；V :≤0.03%；Al:0.02%~0.08%；O :≤0.008%；N: ≤ 0.007%；Ca :≤0.0012%；Remaining is Fe.
Preferably, the steel wire matrix includes the component of following weight percent meter: C:0.071%；Si:0.87%；Mn: 1.51%；S:0.012%；P:0.012%；Mo:0.003%；Ni:0.007%；Cu:0.13%；Cr:0.004%；V: 0.002%；Al:0.04%；O:0.005%；N:0.004%；Ca:0.001%；Remaining is Fe, adds up to 100%.
Preferably, the weight ratio of Mn+Si: 2.3%~2.45%；And weight ratio 1:1.5~2 of Si and Mn.
Preferably, thickness of coated copper layer is 0.25 μm~0.35 μm.
Preferably, in protective gas 100%CO2, 260~290A of welding current, 27~32V of arc voltage, speed of welding Under the parameter of 5.5 ± 1.0mm/S, spatter rate≤5%.
Compared with the existing technology, a kind of low spatter rate ER50-6 gas shielded solid welding wire of the present invention has following excellent Gesture:
(1) present invention realizes the control to particle transfer form, ensure that molten by adjusting the constituent content of steel wire matrix The stability for dripping transition achievees the purpose that reduce spatter rate；
(2) present invention is realized by element regulation and the control of thickness of coated copper layer to steel wire matrix to welding procedure The raising of performance promotes gas shielded solid welding wire welding quality.
Regulating and controlling effect mechanism:
Solid welding wire especially 100%CO under gas shielded arc welding2Under gas shield, the molten drop that wire melting is formed is with short It passes by cross and be transitioned into molten bath with the quick-fried disconnected mode in root, therefore generate more spatter.The present invention uses 2 kinds of measure realities Now reduce spatter purpose: 1, using in component of weld wire C, Al, Si+Mn, O, N, Ca element control realize to electric arc Reach raising molten drop surface tension with the good deoxidation effect in molten bath, reduces droplet size and realize from big drop-wise transition to droplet-shaped Transition achievees the purpose that reduce spatter to mitigate the quick-fried disconnected severe degree of molten drop root bottleneck；
Control C element content can be reduced the yield of bottleneck CO gas, and quick-fried disconnected degree can obtain part control, Al member Element is strong deoxidier, and deoxidation and nitrogen fixation can be played in content range of the present invention has fine effect to droplet size is reduced Fruit；
Composition silicate (the MnOSiO that Si+Mn combined deoxidation is formed2) be easy to upper lift-off slag and prevent slag inclusion, Si, The ratio of Mn is controlled can be achieved in the range of the weight ratio of the range of 1:1.5~2 and Si+Mn are 2.3%~2.45% Preferable deoxidation and de- slag effect；
2, coppered welding wire layer thickness control guarantees that the coverage rate of welding wire surface copper film is close in 0.25um~0.35um 100% realizes welding process welding wire and the conductive smooth arc stability of copper ignition tip, and layers of copper is blocked up easily layers of copper binding force occurs not Foot falls copper scale obstruction ignition tip, and the thinning coverage rate on steel wire matrix of layers of copper, which has decline, influences conductive effect.
