Description
The present invention relates to a kind of low-carbon high-manganese, the little titanium of silicon, aluminium high-ductility submerged arc welding wire, is a kind of welding material, is mainly used in submerged-arc welding, is specially adapted to the steel pipe welding of oil, letter shoot line.
Welding wire for submerged-arc welding is one of submerged arc welding three big raw material, after extensive employing submerged-arc welding process method, require welding wire to have anti-pore, the cracking resistance seam, high-speed welding (speed of welding guarantee 1.6-2.0 rice/minute) etc. performance, and the weld metal that requires to obtain has certain intensity and toughness, therefore the research of welding wire is being carried out always, at first be to reduce S in the welding wire, objectionable impurities content such as P, next reduces C content, with the solderability of raising welding wire and the toughness of weld metal, moreover be in welding wire, to add Ni, Cr, elements such as Mo improve weld metal toughness, in October, 85, welding wire H08MnMoNiTiA recommended in Tsing-Hua University in the experimental study of pipe line steel WX60 weld seam malleableize, wherein Ni content is 0.9-1.2%, Mo content 0.3-0.5%, the main mechanism of Strengthening and Toughening is solid solution, separate out or dislocation strengthening etc., but sometimes strength and toughness you can't have both at the same time, the intensity height, but toughness is low, and Ni, Cr, the adding of elements such as Mo greatly improves the welding wire cost, is difficult to popularize.
In addition, existing welding wire adopts the open hearth smelting technique, make C in the welding wire, S, P content can not fall very lowly, 0.02%≤S<0.04%, 0.03%≤P≤0.04%, C 〉=0.08%, and smelt difficulty, do not have vacuum outgas, pernicious gas content height such as nitrogen, hydrogen, oxygen, little Ti, little Al component content are wayward, can only control into amount.
The invention provides the high Mn of a kind of low C, the little Ti of Si, Al high-ductility submerged arc welding wire, can make the weld metal that obtains that high strength is not only arranged, and high tenacity is arranged, and cost is low, easily promote.
Technical scheme of the present invention is: adopt the relatively abundanter Mn of domestic mineral resources, Si element to replace element solid solutions such as price high Ni, Cr, Mo to strengthen, utilize little Ti to handle crystal grain thinning, improve toughness, add trace of Al and improve the weld seam welding technological properties, make the weld metal that obtains that high strength not only be arranged, and high tenacity is arranged.
Main Ingredients and Appearance content is (%): C≤0.10 in the welding wire of the present invention, Si≤1.0, and Mn≤2.50, Ti≤0.10, Al≤0.10, S≤0.01, P≤0.02, and welding wire of the present invention and SJ101 solder flux coupling could guarantee that weld seam has preferable performance.
The present invention compared with prior art, its weld seam has the excellent comprehensive performance under the situation that does not contain elements such as Cr, Ni, Mo, advantages of higher tensile strength and good low-temperature impact toughness are arranged, meet the welding requirements of X52-X70 level pipe line steel in the carrier pipe API5L of the American Petroleum Institute (API) standard, and CVN
-40 ℃〉=200J reaches external advanced level; In addition, this welding wire can adopt the large-line energy high-speed welding, not preheating before the weldering, and postwelding is applicable to single or multiple lift, the requirement of single or double kinds of processes without heat treatment, and various coiled sheet thickness; Cost is low, and only 3300 yuan/ton of this copper plating soldering wire costs of φ 4mm are equivalent to common H08A welding wire price, than low 2000 yuan/ton of Ni of the same type, Cr type welding wire cost.
Embodiment: the present invention adopts low S, P concentrate iron powder, 300 tons of compound oxygen blast technology in the end, top, furnace outer refining technology, vacuum degassing technology, the high-speed wire rolling technology, just can obtain the welding wire of low C, low S, P, low nitrogen, hydrogen, oxygen residual gas, and can control the content of little Ti, little Al, use high Mn, Si solid solution ferrite, low nitrogen competence exertion Ti increases the effect of nucleus, crystal grain thinning, low S, P, Ca handle and reduce the weld seam deviation, have improved toughness, and Al can improve the processing performance of weld seam welding.
The present invention has refined a stove through Shanghai Baoshan Iron and Steel General Plant with 300 tons of converters, and main component content is (%): C 0.066 in this stove welding wire, and Si 0.79, and Mn 2.13, and S 0.007, and P 0.014, and Ti 0.03, and Al 0.01.
Welding wire of the present invention can be made into φ 4.0mm(and welds usefulness automatically); φ 1.60mm(semiautomatic welding with) etc. plurality of specifications; require electric current 500A, voltage 30V during interior the weldering; require electric current 850~900A during outside weld; voltage 42V, thickness of slab 6~9mm are without bevel, and thickness of slab 10~13mm opens V-butt; this welding wire is suitable for submerged-arc welding or gas shielded arc welding, can be used for the welding with steel pipe welding and bridge, building, pressure vessel, vessel, vehicle, production platform etc. of oil, natural gas transmission pipeline.
Welding wire of the present invention and fluorine alkalescent sintered flux SJ101 are complementary, and X60, X65, X70 mild steel steel plate coiled sheet are carried out the spiral welded pipe welding, and the impact flexibility of postwelding sampling and measuring weld metal is as follows:
Embodiment gained weld metal impact flexibility
