In the present invention, welding wire can use vacuum induction furnace smelting to produce, and also using electric furnace secondary refining method can be added to smelt
Production, as long as the final chemical composition of welding wire can meet the requirement of the above content of the invention.
In order to verify the effect of the present invention, below by two embodiments compared with three comparative examples.
Table 1 is the basic chemical composition of embodiment nickel-based welding wire (weight is than %)：
The effect of each element and the original being in using these elements in the range of Composition Control in welding wire will be analyzed below
Cause.
C:Solubility very littles of the C in austenitic based alloy, when alloy cools down from solid solubility temperature, C was in
Saturation state, when receiving sensitized treatment, C and Cr form carbide (predominantly (Cr, Fe)23C6Type) separated out in crystal boundary, it can cause
The poor Cr of grain boundaries, reduce the anti intercrystalline corrosion ability of deposited metal, it is therefore desirable to C content is any limitation as, C content should control
Less than 0.04%.
Si:Si can be used as alloying element, illeffects again be present.First, Si can be used as deoxidier, and it is anti-to participate in deoxidation
Should, a small amount of Si can improve the manufacturability of TIG welderings, increase the wellability of liquid metal, improve figuration of bead, Si can also in addition
Improve the intensity of material；But then, Si can form Low melting point eutectic, increase fire check sensitiveness, therefore in alloy
Si factor is considered during design.Present invention design Si content is can be controlled between 0.1-0.2%.
Mn:Mn addition is advantageous to the resistive connection crystalline substance cracking performance of abros.On the one hand, Mn preferentially with S combination shapes
Into MnS (1610 DEG C of fusing point), reduce S and form Low melting point eutectic (such as：Ni-Ni3S2645 DEG C of fusing point) tendency so that Ovshinsky
Body-sulfide eutectic temperature improves；On the other hand, increase solid liquid phase surface energy, reduce crystal boundary low melting point eutectic liquid film forming
Possibility, it is suppressed that S, P detrimental effect, so as to reduce deposited metal solidification cracking formability.Meanwhile Mn is deoxidation again
Agent, the oxygen content in weld metal can be reduced, reduce the condition to form silicate, it is considered that, added in weld metal
1% Mn cans reach de- S purpose, but Mn has strong segregation tendency in Ni-based weld metal, is deposited in weld seam
Pin Mn areas and rich Mn areas.When amount containing Mn is insufficient in weld seam, poor Mn areas can produce high temperature because lacking Mn and not reaching de- S purpose
Crackle, therefore enough Mn should be contained in weld seam, even if segregation be present, also ensure that poor Mn areas there can be enough Mn to take off S, so as to
S illeffects is reduced, improves the crack-resistance sensitivity of material.As a whole, Mn elements in 690 welding wire deposited metals with oxygen
The form of compound is present on crystal boundary, serves pinning crystal boundary, prevents the effect of Grain Boundary Sliding, in addition, Mn addition reduces S
With the illeffects of the impurity such as P, the sensitiveness of the anti-Edge crystal crack of material is improved.
Al、Ti:The main function of Al, Ti in nickel-base alloy mother metal improves the intensity of alloy for improvement alloy property.And
Al, Ti have deoxidation in Ni-based weld seam, can also improve intensity by solid solution and precipitation strength.Alloying element and oxygen
Affinity is stronger, and the oxidization burning loss ratio of the element is bigger in welding process, and transfer coefficient is smaller, Al, Ti to oxygen affinity compared with
By force, scaling loss in welding process be present, with the increase of Al, Ti content, Al, Ti scaling loss amount also increase in welding process, and
Oxygen content is but always held at a lower value in weld seam.Al, Ti scaling loss amount increase, Al, Ti oxide formed in weld seam
Also increase, Al, Ti oxide and impurity element Ca, Mg oxide buildup formed are grown up, because the oxide in weld seam increases
The mobility in weld seam molten bath is deteriorated, and the oxide particle after these agglomerations is just not easy emersion molten bath, and final residue is welding
In seam or face of weld forms spot defect.Meanwhile Al, Ti scaling loss weaken it and strengthens the effect of weld seam, Al controls exist
0.1-0.3%, Ti are controlled in 0.5-0.7%.
S:S is harmful element in Ni based alloys.S solubility very little, easily forms cyrystal boundary segregation in nickel-base alloy, produces
The sulfide of low melting point eutectic, is segregated in crystal boundary, and grain boundary separation, i.e. solidification cracking are formed in the presence of thermal strain.Should be strict
Control, reduces its content as far as possible, and S contents are controlled in the invention<0.003%.
P:Influences of the P to nickel-base alloy is similar to S, Pb, though content is seldom in the alloy for it, can not underestimate the harmful of it
Effect, P mainly form Low melting point eutectic with Ni in the alloy, are segregated in crystal boundary, increase incomplete fusion zone width, promote crackle
Tendency increase, so, P contents in nickel-base alloy must control is less than 0.005% in bottom line, S+P total contents "
Zr、B:Zr segregations in foundry alloy to crystal boundary, reduce grain boundary defects, improve crystal boundary adhesion, reduce grain boundary decision
Speed, so as to slow down dislocation climb, strengthen crystal boundary, meanwhile, Zr segregations reduce interface energy, change the form of crystal boundary, subtract in crystal boundary
The size of small crystalline phase, but in weld seam, Zr and O binding ability are strong and are oxidized easily scaling loss, and Zr and B easily cause crystallization
Crackle, the Zr contents in welding material are controlled below 0.005%, B content is controlled below 0.001%.
Mg、Ca:It is the alloying element for especially needing to control according to Ca, Mg of the present invention, the control of its content and spot defect
Closely related, easily there is spot defect in this in welding process at the scene in welding wire at present, again without good control method, reason
It is that it only controls Ca, Mg as in general impurity element, the binding ability of Ca, Mg and oxygen is very strong, the CaO and MgO of formation
Deoxidation products Al in easy and welding process2O3And TiO2Agglomeration formation field trash remains in formation point-like in weld seam and lacked
Fall into, defect is mainly that Ca, Mg, Al, Ti oxide buildup are grown up and formed.It is therefore necessary to Ca, Mg are controlled extremely low
Below scope, Mg<0.005%, Ca<0.005%.
Ta:Tantalum element about 80% enters γ ' phases in nickel-base alloy, forms γ ' phases, and after welding material welding
It is mainly γ austenites and some carbide that phase composition is wished in weld(ing) deposit；Meanwhile tantalum element is a kind of strategic element,
It is expensive, it should try one's best and use less.Therefore, Ta is controlled in the present invention below 0.02%.
Cu、Co、Mo:Cu presence easily to form the second phase in welding process in nickel-base alloy, improves alloy
Hot cracking tendency.Therefore, Cu should be controlled below 0.02%.Under radiation parameter, to make Co constituent contents as far as possible low, the present invention
Control is below 0.01%.In the present invention, Mo control of element is below 0.5%.
Nb：Nb is solution strengthening element in nickel-base alloy, is ageing strengthening element again, can be improved in weld seam between atom
Adhesion, weld seam stabilizing, enhancing weld metal intergranular corrosion resistance ability, Nb are that strong carbonization combines element, it and C binding ability
Stronger than Cr, generation NbC reduces the segregation of C on crystal boundary, so as to reduce M23C6And M7C3Formation, reduce crystal boundary poor Cr.Nb simultaneously again
It is nitride forming element, Al, Ti and the N that can be substituted in alloy form compound, and play a part of solid N and strengthen matrix.Cause
This, uses appropriate Nb to substitute Al, Ti in alloy and, to reduce the scaling loss of Al, Ti in weld seam, reduces the formation of oxide, make up simultaneously
The effect of the reinforcing weld seam weakened because reducing Al, Ti, this be in the present invention important control spot defect factor it
One of one, and obtain the condition of Strengthening and Toughening weld seam.In the present invention, Nb controls are between 2.1-2.6%, preferably 2.2-2.5%.
Ni、Cr、Fe:Ni is austenitic matrix, is stable austenite element；Cr mainly plays solution strengthening effect, and carbon
Compound formation element, Cr are the most important elements in stable alloy surface, and it forms anti-oxidant and anti-corruption on the surface of matrix material
The protective layer of erosion, alloy has good corrosion resistance when Cr contents reach 30%；Low-alloyed cost can drop in Fe addition,
Control is 8.5 one 10.5%.
O、N:O is in the material inevitable relict element, and it is not the necessary element in alloy, in all situations
Under, it is more low better by oxygen limit below 0.005%.N can improve the intensity of weld(ing) deposit, and general control exists
Between 0.02-0.04%.
