Description
Technical Field
The invention relates to the field of welding wires and preparation thereof, in particular to a tungsten electrode argon arc stainless steel welding wire and a preparation method thereof.
Background
The E304L solid welding wire is an austenitic stainless steel solid welding wire, and through the design of high nitrogen and low nickel, the alloy cost is effectively reduced, and the technical additional value of the product is improved. It has the characteristics of corrosion resistance, high strength, light weight and easy processing. Therefore, the E304L solid welding wire is often matched with QN1804L steel and corresponding materials, and is widely applied to the fields of buildings, rolling mills, decorations, kitchen and bathroom products, marine ranches and the like.
However, the QN1804L steel has higher service strength, and the strength of the E304 series welding material product cannot be matched with the steel along with service discovery. Even the E308L and E316L cannot meet the requirement of higher strength, and the E308L and E316L have low cost performance. Therefore, it is always one of the research and development directions in the industry to develop a welding material that can be better matched with the QN1804L steel and the corresponding material.
Disclosure of Invention
The invention aims to provide a tungsten electrode argon arc stainless steel welding wire which can meet the use requirements on QN1804L steel and corresponding materials, and has high strength and cost performance.
The technical scheme for realizing the first purpose of the invention is as follows: the tungsten electrode argon arc stainless steel welding wire comprises the following chemical components in percentage by mass: c is less than or equal to 0.03 wt%; si: 0.65-1.2 wt%; mn: 3.5-5.5 wt%; p is less than or equal to 0.03 wt%; s is less than or equal to 0.01 wt%; cr: 18-19.5 wt%; ni: 3.5-4.5 wt%; cu: 2-3 wt%; n: 0.2-0.3 wt%; nb: 0.25-0.5 wt%; mo is less than or equal to 0.5 wt%; the balance being Fe and unavoidable impurities. The tensile strength of the argon tungsten-arc stainless steel welding wire prepared by the formula is more than or equal to 680Mpa, and the elongation is more than or equal to 30%.
Preferably, the chemical components comprise the following components in percentage by mass: c: 0.018 wt%; si: 0.81 wt%; mn: 4.25 wt%; 0.018 wt% of P; s: 0.004 wt%; cr: 19.21 wt%; ni: 3.82 wt%; cu: 2.71 wt%; n: 0.24 wt%; nb: 0.36 wt%; m: 0.14 wt%; the balance being Fe and unavoidable impurities.
The second purpose of the invention is to provide a preparation method for preparing the argon tungsten-arc stainless steel welding wire
The technical scheme for realizing the second purpose of the invention is as follows: the invention discloses a preparation method of a tungsten electrode argon arc stainless steel welding wire, which comprises the following steps:
s1, preparing chemical components according to the formula;
s2, smelting the chemical components in the step S1, casting the smelted chemical components into a billet, and rolling the billet into a wire rod;
and S3, performing normalizing and high-temperature tempering heat treatment on the rolled wire rod, then performing reducing drawing, performing 1-2 times of annealing heat treatment in the drawing process, and finally drawing and cutting into the welding wire.
The normalizing and high-temperature tempering heat treatment in the step S3 includes the following steps: normalizing at 1080 +/-20 deg.c and maintaining for 2-3 hr; then tempering at 760-780 ℃ and keeping the temperature for 1.5-2.5 hours.
Generally, the wire is cut into a wire with a diameter of 1.2mm, 1.6mm, 2.0mm, 2.5mm, etc. and a length of 1000mm, 300mm, 500mm, etc. Wherein the diameter error is +/-0.02 mm, and the length error is +/-2 mm.
The invention has the positive effects that: (1) because the welding materials used by the QN1804L are not matched with each other, only the welding materials such as high-matching E316L and E312 can be matched with the welding materials, so that the use cost performance of the QN1804L is reduced; even in this case, the strength of the welding material such as E316L or E312 cannot satisfy the high strength requirement. The invention can effectively solve the problems, and when the novel light-weight LED lamp is used in corresponding environments, thinner plates can be adopted, so that the weight is lighter.
(2) The invention can be matched with the corresponding material of QN1804L steel mainly because of the following reasons:
the invention is low alloy, the Ni content is low, and the Ni content of the conventional E304 is more than 8 percent;
secondly, the corrosion resistance is good, and compared with the E304 series, Cu and Nb corrosion-resistant elements are added;
and thirdly, the invention has high strength because the N content is increased compared with the E304 series.
And fourthly, the comprehensive cost is lower than that of the conventional E304L, the corrosion resistance is better, and the strength is more suitable for being matched with QN 1804L.
