Abstract
The invention discloses a nickel alloy strip welding method and relates to a nickel alloy strip, in particular to a method for merging coil welding of a high-gas-content pure-nickel alloy strip. During welding, a plasma welding method is adopted, and welding is conducted with filler wires under the hydrogen and argon shield. The nickel alloy strip welding method adopts the plasma welding method, the wire filling process and the hydrogen and argon shield measure. The technical problems which exist during merging coil welding of the pure-nickel alloy strip with high gas content (the oxygen content is more than 50ppm) are solved through control over heat input and protective effect during welding by means of the plasma welding method and welding wire adding and hydrogen adding; the product quality is guaranteed; the production requirement is met; the production efficiency is improved and the yield is increased. Meanwhile, the welding of pure-nickel strip products with high nitrogen and hydrogen gas content is achieved. The method is also suitable for welding of pure-nickel products of other specifications, such as bars and wire rods and pure-nickel products with low gas content.
Description
Technical field
A kind of nickel alloy strip welding method, relates to a kind of nickel alloy strip, and particularly the method for volume welding spelled by high gas content pure nickel alloy band.
Background technology
At present; spell in volume welding production process at pure nickel alloy band; non-vacuum melting explained hereafter mother metal gas content is at more than 50ppm; vacuum mother metal gas content can reach below 20ppm; in general welding process; adopt conventional soldering method can realize good welding as TIG weldering etc. and measure comprise the means such as surface treatment, gas shield; ensure the reprocessing such as the rolling of the follow-up roll coil of strip, annealing; General Requirements weld seam is followed mother metal processing thickness and is reached 0.05mm and do not rupture, and meets the requirement of overall roll coil of strip product quality with mother metal simultaneously.But gas content requires too low, need with vacuum induction melting even vacuum induction add vacuum consumable duplex technique and could realize, cause fusion process complicated, production efficiency reduction, cost increase, is unfavorable for Production requirement.
Adopt the pure nickel alloy mother metal gas content of non-vacuum melting explained hereafter generally at more than 50ppm, by realizing single batch of (gas content is higher than 50ppm) pure nickel mother metal reprocessing requirement, and product quality meets client's instructions for use.But due to production requirement, need to realize Kinds of Heavy Coil and produce and the supply of material, improve lumber recovery and production efficiency.But adopt general welding method and process conditions to be difficult to realize good welds, mainly due to a following difficult problem: (1) due to mother metal gas content higher, welding process generating material internal oxidation scaling loss and pore, weld seam is difficult to shaping, this process is equivalent to the small-sized fusion process of alloy, and there is no the refining means such as degassed, removal of impurities, gas content enrichment can be caused; (2) pure nickel material particularity, more stable under normal temperature, along with temperature raises, its performance starts change, and the ability of its absorbed nitrogen, hydrogen, oxygen obviously rises thereupon.Nickel is oxidized a little in 500 DEG C of high temperature airs, when temperature reaches 750 DEG C, then and vigorous oxidation.Along with weld seam oxygen content rises, tensile strength and the hardness of weld seam obviously rise, and plastic property of weld bead obviously declines, and weld seam becomes fragile because of the pollution of oxygen; Nitrogen can affect weld strength, hardness, plasticity, and the impact flexibility of weld seam is obviously reduced.(3) conventional soldering method welding measure is limited; as TIG weldering, MIG weldering etc.; especially because heat input, protected effect etc. cannot reach requirement; cause the defects such as weld dimensions generation pore, coarse grains, tissue embrittlement; do not reach following process requirement, cannot ensure that pure nickel material weld performance meets GB and client uses.
Summary of the invention
Object of the present invention is exactly the deficiency existed for above-mentioned prior art, there is provided and effectively can solve the technical barrier of high gas content pure nickel alloy band in spelling volume welding process, ensure product quality, meet production requirement, enhance productivity and lumber recovery nickel alloy strip welding method.
The object of the invention is to be achieved through the following technical solutions.
A kind of nickel alloy strip welding method, it is characterized in that its welding process adopts plasma welding method, under hydrogen+argon shield, filler wire welds.
A kind of nickel alloy strip welding method of the present invention, is characterized in that its Control Welding Process penetration ratio, makes the dilution rate of weld metal be less than 50%.
A kind of nickel alloy strip welding method of the present invention, is characterized in that the hydrogen volume of its welding process hydrogen+argon gas is 0-16% than content.
A kind of nickel alloy strip welding method of the present invention, adopts " plasma welding method "+" silk filling technique "+" joining hydrogen+argon shield " measure.Adopt plasma welding method by adding welding wire, join hydrogen and control the input of welding process heat and protected effect and solve high gas content (oxygen content is at more than 50ppm) pure nickel alloy band and spelling the technical barrier in volume welding process, ensure product quality, meet production requirement, enhance productivity and lumber recovery; Solve the Welding Problems of high nitrogen, hydrogen content pure nickel strip product simultaneously.The method is also applicable to other specifications as the pure nickel such as bar, wire rod Product jointing and low-gas content pure nickel Product jointing.
Detailed description of the invention
A kind of nickel alloy strip welding method, its welding process adopts plasma welding method, and under hydrogen+argon shield, filler wire welds.
A kind of nickel alloy strip welding method of the present invention, adopts plasma welding method, and because the energy density of plasma arc is large, penetration ability is strong, and production efficiency is high; Weld penetration is than large simultaneously, and heat affected area is little, and weldquality is high.Single face welding and double face shaping is realized by adopting Plasma Welding.
A kind of nickel alloy strip welding method of the present invention, the filler wire composition selected by welding, should make weld seam have higher crack resistance and weak oxidisability, to ensure more alloy transfer, penetrate in weld metal.Select the nickel-base alloy bare welding filler metal containing deoxidant elements such as Ti, Al, Nb, and suitably control penetration ratio, the dilution rate of weld metal is no more than 50%.
A kind of nickel alloy strip welding method of the present invention, adopts argon gas+hydrogen shield: play a protective role on the one hand, hydrogen butt welded seam welding process plays reduction effect, reduces oxygen content; Arc temperature and electric arc electric-field intensity can be improved on the one hand, more effectively electric arc heat can be passed to workpiece, reduce welding current, improve speed of welding, reduce the input of weld seam heat, improve weld appearance.Regulate between 0-16% according to thickness of strip hydrogen volume content, band is thinner, and hydrogen content is fewer.
One of the present invention high gas content pure nickel alloy band welding method, the method is applicable to other specifications as the pure nickel such as bar, wire rod Product jointing, is also applicable to the welding of low-gas content pure nickel.
