Description

A kind of high-strength weathering steel gas protecting welding wire steel and welding wire
Technical field
The invention belongs to technical field of welding materials, be specially a kind of high-strength weathering steel gas protecting welding wire steel and welding wire, be particularly useful for welded high-strength and there is gas protecting welding wire steel and the welding wire of the steel grade of high durable performance requirement.
Background technology
Gas shielded arc welding has that production efficiency is high, welding usability good, welding cost is low, energy-conservation, adapt to all-position welding, be convenient to realize automation, the advantage such as weldquality is good, be now widely used in the welding production of the important feature parts such as engineering machinery, shipping vehicle, railroad bridge, skyscraper and pressure vessel.In recent years, along with the development of smelting technique, and controlled rolling, control cold-peace micro alloying element application, the future development of the performance forward high strength of steel, high tenacity and high-weatherability, to reduce material consumption, alleviate construction weight, improve structural behaviour, security and service life.The production of these high-strength tenacity weathering steels meets the demand that railway speed increase loss of weight and bridge spanning the sea, military project naval vessel, oil pipeline etc. require its steel grade high durable, high strength, high tenacity, but the performance of Welded Joints it is also proposed higher requirement while steel performance improves, welding point must have the obdurability suitable with mother metal and weather resistance, this is with regard to Welded Joints, and then proposes higher requirement to welding material.
Can ensure in existing welding material that the intensity of weld metal reaches 600MPa; and the gas protecting welding wire with good toughness, plasticity and weatherability is also few; publication number is that the patent of CN101020279A proposes the grade gas shielded welding wire of a kind of 600MPa; the tensile strength of its deposited metal is greater than 600MPa; and have good toughness and plasticity, but it does not have weatherability.Publication number be CN1358607A patent discloses a kind of high-toughness gas protective welding wire for low alloy high-strength steel, it has certain weather resistance, but is only applicable to the welding of intensity higher than 700MPa steel.Publication number is that the patent of CN1413795A proposes a kind of Super-low carbon high-intensity gas protection welding stick material; it is mainly in order to realize the object that sensitiveness is little, commissure metal is close with mother metal results of property of commissure metal cold crackle after welding, but fails the problem of the welding material atmospheric corrosion resistance matched solving high-level weather-proof series structure steel grade.Publication number is that the patent of CN102441745A proposes a kind of weather-resistant gas-shielded solder wire for high-speed train bogie; this welding wire is a kind of weather-resistant gas-shielded solder wire being used in the welding of CRH3 motor train unit bogie framework specially; the weather-resistant gas-shielded solder wire solving prior art high speed train bogie depends on import always; the problems such as cost is higher; this welding wire has certain weatherability, but is only applicable to the welding of intensity lower than 500MPa steel.
Summary of the invention
The object of the present invention is to provide a kind of welding performance to stablize, high-strength weathering steel gas protecting welding wire steel that splash little, pore-free, commissure metal and high-level weather-proof series structure steel grade performance match and welding wire.
The present invention is a kind of high-strength weathering steel gas protecting welding wire steel, it is characterized in that the percentage by weight of chemical composition is: C:0.015%-0.08%; Mn:0.70%-1.50%; Si:0.20%-0.80%; Ni:0.50%-1.30%; Cu:0.1%-0.4%; Nb:0.03%-0.10%; Cr≤0.20%; S≤0.015%; P≤0.020%, surplus is iron and inevitable impurity.
The present invention is a kind of high-strength weathering steel gas protecting welding wire, and the percentage by weight of its chemical composition is: C:0.015%-0.08%; Mn:0.70%-1.50%; Si:0.20%-0.80%; Ni:0.50%-1.30%; Cu:0.15%-0.50%; Nb:0.03%-0.10%; Cr≤0.20%; S≤0.015%; P≤0.020%, surplus is iron and inevitable impurity.
There is copper plate on the surface forming above-mentioned high-strength weathering steel gas protecting welding wire, and in copper plate, Cu content accounts for the 0.05%-0.25% of welding wire gross weight.
Of the present invention is in use by mist (80%Ar+20%CO 2) protect and weld.
Steel for welding wire of the present invention and welding wire Design of Chemical Composition are according to as follows:
C is the important element ensureing weld strength, but is also that weld seam causes crisp element, and too high cracking resistance and the impact flexibility that can reduce weld metal of C content, so strictly will control the C content in welding wire.Si, Mn play deoxidation and strengthen welds effect when welding, Si, Mn form oxide inclusions by deoxygenation or oxygen sulfur compound is mingled with, prevent the formation of the iron sulfide causing fire check, suitable Si, Mn content can make welding wire have excellent welding technological properties.Ni in welding wire is conducive to the low-temperature impact toughness improving weld metal, reduce brittle transition temperature, but too high weld seam and the mother metal performance difference of not only making of Ni content strengthens, and also will increase welding wire cost.Appropriate Cu can improve weld seam obdurability and atmospheric corrosion resistance, when Cu content is less than 0.5%, improves weld strength in solution strengthening mode, and improve acicular ferrite content, when Cu content is greater than 0.5%, to separate out mode strengthen welds, but butt welded seam toughness is unfavorable.Nb can limit the transformation of pro-eutectoid ferrite, and expands the region of acicular ferrite transformation, thus Absorbable organic halogens obtains a large amount of acicular ferrite structures in weld seam, and Nb also helps Austenite Grain Growth in suppression weld seam, thinning weld metal structure.Cr, S and P of comprising in the present invention, it is residual volume in steel.
This high-strength weather-proof steel for welding wire used for gas shield welding, can adopt vacuum induction furnace smelting to produce, and electric furnace also can be adopted to add secondary refining method and smelt and produce, as long as the final chemical composition of welding wire can meet the requirement of above summary of the invention; In addition, the whole smelt production of welding wire and process and common welding wire for gas shielded welding do not have difference.
The present invention has following characteristics and beneficial effect:
1, welding wire steel smelting process of the present invention is stable, easy to implement, the rolling of steel billet and welding wire draw dial, the function admirable such as copper facing, meet the solder technology requirement of the steel series such as welded high-strength high-weatherability a new generation engineering machinery, naval vessel, ocean, oil pipeline, railroad bridge, skyscraper and high-pressure bottle.
2, welding wire of the present invention is used for the welding of 600MPa intensity rank steel grade, adopts rich argon mixture gas (80%Ar+20%CO 2) protection time, deposited metal yield strength ReL>=500MPa, tensile strength Rm>=600MPa, percentage elongation A>=25%, standard ballistic work AKv>=40J at-40 DEG C.
