Technical field
The invention belongs to field of welding material, and in particular to a kind of polar region ship steel high-strength and high ductility welding wire for submerged-arc welding and its make
Use method.
Background technology
For the low-temperature steel of polar region shipbuilding, because applying in low-temperature cold marine site, marine environment is complicated and changeable, be through
By the lot of challenges that ultralow temperature, ice and snow abrasion, the collision of low temperature stormy waves, strong Marine Storm Genesis and frozen soil collision etc. bring, to ship
Design, selection and construction processing of oceangoing ship low-temperature steel etc. propose requirement higher.Ship low-temperature steel requirement in polar region has excellent
Good low temperature combination property of extremely trembling with fear, its structural material not only has intensity high, good plasticity, but also requires -60
DEG C, there is excellent impact flexibility, particularly in the ultra-low temperature surroundings lower steel plate of polar region marine site severe cold to -60 DEG C at -80 DEG C
Fracture toughness requirement is good, and welding performance is excellent.The security requirement of polar region ship Ship Structure is very high, polar region ship steel
Intensity is high, and the low-temperature flexibility requirement to steel plate is very high, and then requires the weld seam of the welding wire for submerged-arc welding and solder flux matching welding for using
Also require that with high-strength, high-ductility characteristic.
Also more and more extensively, the consumption of wlding is growing day by day for the application at home of low-temperature steel welding material.In some weights
When wanting large-scale component to connect, can typically use submerged-arc welding because submerged-arc welding not only efficiency is higher, and welding quality is good.But mesh
The high-intensity low-temperature steel SAW consumable material of preceding actually domestic welding manufacturer production is very limited, and many this kind of wldings are all leaned on
External import.The welding wire for submerged-arc welding used in important high performance ship and extra large work equipment manufacturing is essentially all external at present
Famous brand name, domestic welding wire is kept outside of the door because low-temperature flexibility, especially Fracture Toughness are unstable.In the past to suitable for pipe
The welding wire for submerged-arc welding research of line steel, construction(al)steel, bridge steel plate and steels for pressure vessel use is more, including patent publication No. is
The H 06 C series submerged arc welding wire for novel microalloying constructional steel of CN1701904A, patent publication No. are the height of CN101342645A
Grade pipe line steel high-intensity high-tenacity High Speed Welding welding wire for submerged-arc welding, the low-alloy high-strength that patent publication No. is CN1200317A are high
Toughness welding wire for submerged-arc welding, patent publication No. are public for the high ductility buried arc welding wire for low-alloy super-strength steel and patent of CN1919524A
The number of opening is high-strength high-toughness weld wire for hidden arc welding of pressure container of CN1343544A etc., and their alloy system substantially belongs to
In Si-Mn-Mo-Ti-B and Si-Mn-Ni-Mo systems, because Ni contents are relatively low in welding wire, generally less than 1.5%, although by Ti-
B microalloyings, can be by crystal grain thinning improving toughness to a certain degree, but weld metal low-temperature impact toughness can only expire mostly
The requirement of -40 DEG C of foot, for the fracture toughness index required for the standby welding of extra large frock, all without definite data, it is difficult in pole
Applied on ground ultra-low temperature surroundings ship.

The present invention not only needs to meet the requirement of high intensity, and also needs to obtain low temperature below -60 DEG C fabulous of satisfaction
Toughness reguirements, therefore the toughness of weld seam is improved using ultralow C in design, while the value of Si is controlled 0.6~1.20%
Between, in the case of Ultra-low carbon, obtain good intensity and tough sexual balance.On this basis, using Ni under cryogenic
Premium properties, 0.40~1.00% that Ni, Cr0.30~1.00% and Cu 0.10~0.80% can significantly reduce weld seam is tough
Crisp transition temperature, improve weld seam low-temperature flexibility and stability so that even if weld metal at -60 DEG C also have it is very high
Impact value.Ensure that weld strength reaches more than 510MPa additionally by the solid solution of Mo and Nb, Ti, precipitation, precipitation strength.
