The alloy of the argon-arc-welding rod comprises the following ingredient ranges: 15.5 to 39.0% of Mn, 2.0 to 4.0% of Al, 1.0 to 3.0% of Ni, 1.0 to 2.5% of Fe, 0.1 to 1.0 % of Cr and Cu as rest. The argon-arc-welding rod of the present invention has the advantages that the damping properties, the mechanical properties, the corrosion-resistance properties and the properties of resisting stress corrosion can meet the requirements of high-damping and Mn and Cu-based alloy with different manganese contents for various properties, and the welding technology is favorable.
Description
Manganese cuprio high damping alloy argon arc wire of the present invention is applicable to that manganese content is the argon arc welding of the various high-damping mn-cu-based alloys of 25-65%, and AC and DC all can.
Because vibration and noise have become the public hazards in the world today, particularly some is the military installation of main feature with the disguise, and as submarine, its vibration and noise reducing problem directly has influence on the performance of performance characterisitic.Adopt the high damping alloy material.It is one of effective way of vibration and noise reducing.Present domestic and international various high-damping mn-cu-based alloys of developing because its chemical analysis and performance characteristics determine, cause the welding performance of such alloy relatively poor.When the alloy manganese content is higher, adopt the welding wire welding identical or approximate with the stock composition, not only strength of joint descends significantly, and very high fire check formation tendency appears in weld metal.
The disclosed a kind of component of weld wire of known SU624749 patent, be (to contain 40～55%Mn) and guarantee the damping capacity that joint is required with high manganese content, but measure higher because of it contains Mn, contain Al amount (＜3.0%) on the low side, not only cause welding technological properties poor, and joint mechanical performance and anti-stress corrosion performance reduce greatly, shortcoming such as welding residual stress is bigger, because this alloy contains Fe amount higher (reaching 3.5%), the damping capacity of butt joint has a negative impact again simultaneously.Added elements such as a certain amount of V, B in its alloying component, though a series of shortcomings that its high manganese content produced are had mitigation, V costs an arm and a leg, and adds V, B and will make comparatively difficulty of the smelting technology of alloy and Composition Control.
In view of the existing problem of existing high damping alloy welding wire, the purpose of this invention is to provide a kind of damping capacity that can satisfy high-damping mn-cu-based alloy and require and guarantee the argon arc welding wire that welding technological properties is good, welding point has favorable mechanical performance and anti-stress corrosion performance.
Manganese cuprio high damping alloy argon arc wire alloy component range of the present invention is as follows:
Mn15.5-39.0% AL2.0-4.0% Ni1.0-3.0%
Fe1.0-2.5% Cr0.1-1.0% surplus Cu and general impurity.
Mn guarantees that soldering wire alloy has the basic element of high damping ability, because weld seam has certain penetration ratio, add 15.5-39.%Mn, can guarantee that welding point possesses higher damping capacity, can obtain welding procedure and corrosion resistance preferably again, too high manganese content will make the remarkable variation of welding procedure, corrosion resistance and joint mechanical performance.Cr can significantly improve the decay resistance of alloy, and is rather effective to improving stress corrosion inclination especially, and can improve the mechanical performance of alloy; But during too high levels damping capacity is had adverse effect, so this welding wire determines that its Cr content is at 0.1-1.0%.Al is main intensified element and improves corrosion resistance of alloy, contains Al＜2.5% o'clock, and is little to the mechanical performance influence, contains Al＞2.5% and o'clock begins to occur hardening constituent β, contains Al＞5.0% an o'clock alloy and is tending towards embrittlement; Ni can improve corrosion resistance of alloy can improve the intensity of alloy again under the situation that does not reduce percentage elongation, but damping capacity is had adverse effect; Fe can crystal grain thinning, improve the mechanical performance of alloy, but alloy damping characteristic is had tangible adverse effect when excessive, so content all can not be too high.Determine Al2.0-4.0% Ni1.0-3.0% Fe1.0-2.5% in the component of weld wire of the present invention thus.
Manganese cuprio high damping alloy argon arc wire of the present invention, its damping capacity, mechanical performance, anti-stress corrosion performance etc. all can satisfy the every performance requirement of high-damping mn-cu-based alloy of above-mentioned different manganese content, and welding procedure is superior.
A kind of embodiment that the present invention provides, welding contains Mn amount and for the best soldering wire alloy composition of the high-damping mn-cu-based alloy of 50-60% is: C＜0.1% Si＜0.2% surplus is Cu to Mn34% Al3.5% Ni1.5% Fe1.5% Cr0.3%.
Welding wire with this embodiment alloying component welds 2310 alloys (containing 53%Mn, 4.0%Al, 3.0%Fe, 2.0%Ni 0.5%Cr), the 6b 〉=500MPa of ac argon arc weld joint, α 〉=80.0 degree (d=2a), Q
-1〉=1.77 * 10
-2The 6b of dc argon arc welding weld metal 〉=600 MPa, 6
0.2〉=430MPa, δ
5〉=29%.Two naval vessels five vane propellers that 2310 high damping alloys of developing voluntarily with welding wire repair welding of the present invention China are made, the repair welding situation is as follows:
Right oar: repair welding is carried out in many places such as propeller boss endoporus and small end outer surface, and maximum repair welding size (long * wide * dark) is 55 * 25 * 303mm.
Left side oar: the suction surface of each blade has all carried out the many places repair welding in propeller boss endoporus and five blades, and the full-size of repair welding (long * wide * dark) is 110 * 50 * 5mm.
Screw after the repair welding, in dress ship use on February 1st, 1986, on August 30th, 86 lay up, and examination was used seven months, and check result is weld seam and metal surface, heat affected area densification, bright and clean.Weld seam and mother metal fusion are good, do not find any anomaly, and the repair welding position does not have corrosion, does not have any damage.
Two oars descend water to use in October, 1986 once more, and the inspection that lies up in October, 1988 is no any unusual, still in use now.
