Description
Technical field
The invention belongs to the Lincoln weld connection technology of welding field, arcing welding wire and preheating wire welding are integrated in a welding gun by one specifically, utilize the excess energy of arcing welding wire to melt the welding wire of preheating, thus greatly promote welder and the method for cladding rate while not affecting the input of welding process heat and stability.
Background technology
Lincoln weld is that one forms protection zone by melt flux; electric arc burns the melting electrode welding method of a kind of high efficiency large-line energy carrying out welding wherein; due to multifibres automatic welding mode can be adopted; therefore its odds for effectiveness is obvious, but the phenomenon such as overheated that large-line energy brings also significantly limit the application of this technology in the welding of the heat-sensitive material such as pipe line steel, high-strength steel.Therefore while relatively reducing heat input, how increasing the deposition efficiency of filling metal is the key technology promoting that this method is applied further.
The multifibres multi sphere submerged-arc welding method industrially adopted at present, in some thick plates structures of welding, nearly 3 ~ 6 wire feeding motors are applied, the multiarc welding of 3 ~ 10 root wires can be carried out simultaneously, this multifibres multiarc welding can improve welding efficiency really, but the essence that this multifibres multiarc welding method improves welding efficiency is realized by the method for raising heat input, high heat input causes the heat affected area grain coarsening of mother metal, produce local softening phenomenon, make the mechanical heterogeneity of heat affected area, affect welding quality and serviceability.In addition when welding wire is too much, whole welding equipment will become very complicated, huge, and welds prepares is loaded down with trivial details, and operability is deteriorated, so the scope of application is very narrow.Multifibres weldering conventional at present mainly comprises Double Wire Welding or three wire bonds, and for double wire hidden arc welding, have doublearcing wire submerged arc to weld and fill silk submerged-arc welding, i.e. an arcing welding wire, another root wire sends into molten bath from the side.All there is the unnecessary problem of arc energy in mariages or three submerged-arc weldings, the double wire hidden arc welding that fills silk make use of unnecessary arc energy, but because it sends into molten bath from the side, so welding wire is not easy the center accurately entering into electric arc, the easy like this welding process that causes is unstable, and meanwhile, one-sided insertion welding wire also can make the magnetic field around arcing welding wire asymmetric, cause arc blow, affect the stability of electric arc.Double wire hidden arc welding only with the addition of a welding wire on the basis of original monofilament in addition, and the increase of cladding rate and speed of welding is not comparatively speaking clearly.
Summary of the invention
The present invention is directed to the problems referred to above, propose and put into the heated filament of an eradication edge or add the heated filament of two eradication edge in the both sides of an arcing welding wire in the middle of two arcing welding wires, such arcing welding wire is no more than two, far below the quantity of the arcing welding wire that extensive multifibres welds, can effectively low_input_power fall, avoid the fire damage of mother metal, other two kinds of arrangement modes all have the advantage of high cladding rate, just emphasis is different, the former has two arcing welding wires, heat input is relatively large, may be used for slab or narrow-clearance submerged arc welding, the latter only has an arcing welding wire, there are two heated filaments, such heat input is just relatively little, be suitable for the little sheet material of thickness or large groove welding.Meanwhile, heated filament and arcing welding wire integrate, and effectively simplify the complexity of equipment, operate more simple and convenient, and due to the parallel placement of each welding wire, both sides welding wire almost symmetry, so can not be subject to the impact of arc blow, electric arc can not lateral deviation.In the middle of two arcing welding wires, put into the heated filament arrangement mode of an eradication edge, heated filament is in the centre of two electric arcs, so heat its fusings enough that electric arc is unnecessary; Add in the arrangement mode of the heated filament of two eradication edge in the both sides of an arcing welding wire, heated filament and arcing welding wire close to each other, send to along a direction, heated filament is easy to the center entering electric arc, so also can melt smoothly.If size and the wire feed rate of heated filament and arcing welding wire are close, so integrated intelligent temperature-adjustable hot-wire submerged arc welding technology improves 200% compared to the cladding rate of common submerged-arc welding, also improves 50% compared to double wire hidden arc welding.So this technology has advantage clearly.

, can be obtained by formula, when adding the heated filament of varying number, heat input can not change, and namely not needing to change total hot input value can increase deposition rate.In addition because heated filament has just reached very high temperature before entering molten bath, so very easily melt, namely can send into molten bath with very high wire feed rate, therefore cladding rate can be promoted largely.
(3) speed of welding is improved.Under certain welding parameter, when cladding rate promotes, speed of welding can be promoted naturally accordingly.In commercial Application, this is by remarkable improving production efficiency.
(4) fall low_input_power, reduce distortion.The deposition rate that integrated intelligent temperature-adjustable hot-wire submerged arc welding technology obtains promotes again in conjunction with its stable welding effect, can realize speed of welding faster in heat input lower than when mariages or monofilament welding.Therefore, when integrated heated filament technique initialization is identical productivity levels, heat input will reduce.The reduction of heat input can reduce distortion, and when welding thin plate and high thermal output responsive type mother metal, this advantage is especially outstanding.Also reduce simultaneously multilayer welding layer by layer between cool time, drastically increase production efficiency.
(5) solder flux consumption is reduced.The welding productivity due to integrated heated filament skill upgrading, less welding bead just can complete weld job, and therefore solder flux consumption significantly reduces.The technology stability improved reduces solder flux consumption too, and the solder flux needed for per kilogram deposition welding wire is less.
