Description

A kind of active twisted wire welding wire reducing spatter loss coefficient
Technical field
The utility model relates to a kind of welding material, particularly relates to a kind of active twisted wire welding wire being suitable for the reduction spatter loss coefficient that gas shielded arc welding uses.
Background technology
Along with the fast development of industrial technology, the Welding Structure of maximization, high parameter is increasing, and these Welding Structures need a large amount of cut deal manufacture.Submerged-arc welding, gas shielded arc welding are the main technique of current cut deal welding.Gas shielded arc welding is flexible and convenient to use, and be suitable for the welding of various position, production efficiency is higher, can adopt automatic welding, and therefore, extensive use on Welding Structure is produced, particularly carbon dioxide gas arc welding application is more general.
Gas shielded arc welding welding wire used comprises solid core welding wire and flux-cored wire two class; current domestic conventional gage of wire is 0.8mm, 1.2mm and 1.6mm; increasing gage of wire can increase of weld current, improve welding productivity, but increase of weld current often makes spatter significantly increase.When splashing must increase greatly fettler, reduce welding production efficiency, splash simultaneously and also make the consumption of welding material increase, too increase energy resource consumption.The splashing reducing solid core welding wire gas shielded welding is welding profession problem in the urgent need to address.People start with from aspects such as welding equipment, welding procedure, welding materials, in reduction spatter, take various measure.As: the motion controlling welding wire, the change wire feeding mode control methods, welding current waveform control methods, Surface Tension Transition control methods etc. that promote the droplet transfer to reduce spatter with mechanical force are all reduce to splash by the accurate control droplet transfer of welding equipment (see paper: Meng Qinghua, Qu Zhiming etc., to reduce CO 2the control method that gas shielded arc welding splashes, " Petroleum Engineering Construction " magazine, the 28th volume the 4th phase in 2002).This improvement by welding equipment reduces the method for splashing, and often equipment control is complicated, and application maintenance maintenance is all very inconvenient, and require also very high to the knowledge and skills of welder, equipment investment is large.Reduce to splash by welding condition and then have certain limitation, for specific welding wire and welding equipment, the welding parameter interval of splashing little is smaller, and mostly in small area analysis region, so welding productivity is lower, is difficult to be applied to production.Reduced by the innovation of welding material and optimal design and splash, there is the plurality of advantages that cost is low, need not invest new equipment, easily apply, be subject to people's attention.Research and development flux-cored wire, improvement solid core welding wire are two important directions.
The advantages such as flux-cored wire has arc stability, it is little to splash, chemical composition adjustment is easy, but its there is manufacturing process complexity, cost is high, particularly Wire Performance is not as solid core welding wire, the shortcomings such as remote wire feed poor stability.The Wire Performance of solid core welding wire is good, but its composition adjustment difficulty, spatter is large, arc stability is poor.
Application number is the patent " a kind of multi-strand stranded welding wire " of " 200910027603.X ", that multiply solid core welding wire and flux-cored wire are mixed stranded being integrated, or be integrated stranded for multiply flux-cored wire, make multi-strand stranded welding wire, shortcomings such as its objective is to overcome and increase flux-cored wire diameter, welding wire not easily coils, outspoken nature is poor.Flux-cored wire is adopted to manufacture multi-strand stranded welding wire; the diameter of flux-cored wire accomplishes that below 1.0mm is more difficult; therefore the diameter of multi-strand stranded welding wire is larger; be difficult to use in gas shielded arc welding; submerged-arc welding can only be used for; and the cost of flux-cored wire itself is higher, the cost of the multi-strand stranded welding wire produced can be higher.This patent adopts solid core welding wire to manufacture multi-strand stranded welding wire, mainly solves major diameter solid core welding wire rigidity large, the problem of coiling and wire feed difficulty, can not improve welding arc-stabilising, reduce spatter loss coefficient etc.Application number is " 201120198574.6 " (Authorization Notice No. CN202137516U) patent " one adds triumphant multi-strand intertwisted flux-cored wire "; this patent increases triumphant steel band as conductive layer and protective layer on the surface of multi-strand intertwisted flux-cored wire; this welding wire manufacture difficulty is larger; owing to using multiply flux-cored wire and adding triumphant; make the diameter adding triumphant multi-strand intertwisted flux-cored wire comparatively large, can only submerged-arc welding be used for.The submerged-arc welding of flux-cored wire is used for built-up welding, and bead-on-plate weld requires that the content of alloying element is higher, add triumphant steel band not high due to alloying element content, otherwise be difficult to make the less steel band of thickness, therefore add the triumphant content that can reduce bead-on-plate weld alloying element, do not reach the component requirements of bead-on-plate weld.
Along with increasing gradually of large welded structures application; and day by day harsh (as low temperature, large load, the high temperature etc.) of structure operating condition; the application of cut deal increases gradually; welding job amount increases considerably; user is to low cost, Wire Performance excellence, low spatter, stay-in-grade high efficiency welding material, and the welding wire for gas shielded welding demand being particularly suitable for automatic welding is also more urgent.
