[0024] The preparation method of the welding material for the fusion welding butt joint transition layer of the above-mentioned titanium-steel clad plate, the specific operation steps are as follows:

[0025] Step 1, Smelting

[0026] Weigh the following pure metal powders by weight percentage: Mn3.15-3.35%, Cr18-27%, Cu0.01-0.015%, Ti0.35-0.55%, Co0.03-0.04%, Nb1.8-2.0% , Ta0.2-0.6%, the balance is Ni, put the Ni, Cr, Nb, Ta powder weighed above into the MgO crucible in the vacuum induction furnace for melting, and put the Cr, Nb, Ta powder in the center of the nickel powder After the metal powder in the furnace is completely melted into molten metal, it is refined at 1550°C for 20 minutes, then the temperature of the molten metal is lowered to 1540°C, filled with argon to make the furnace reach 300-380mmHg, and then the weighed Mn, Cu, Add Ti and Co into the molten metal in turn, and pour the molten metal into the ingot mold after stirring for 2 minutes. The pouring tempera...

Abstract

The invention provides a welding material for a butt fusion welding transition layer of a titanium-steel composite board and a preparation method of the welding material. The welding material comprises the components in percentage by weight as follows: 3.15%-3.35% of Mn, 18%-27% of Cr, 0.01%-0.015% of Cu, 0.35%-0.55% of Ti, 0.03%-0.04% of Co, 1.8%-2.0% of Nb, 0.2%-0.6% of Ta, smaller than or equal to 0.02% of C, smaller than or equal to 0.025% of Si, smaller than or equal to 0.002% of P, smaller than or equal to 0.75% of Fe and the balance of Ni, wherein the sum of the weight percentages of the components is 100%. The diameter of the welding material is small, weld microstructures of a titanium layer and a steel layer of the titanium-steel composite board can be effectively connected through manual TIG (tungsten inert gas) welding or MIG (metal inert gas) welding, butt fusion welding of the titanium-steel composite board is realized, and a welded joint has excellent strength and toughness; and the welding material is simple in preparation method, low in cost and suitable for batch production.

Description

technical field [0001] The invention belongs to the technical field of metal material welding, and in particular relates to a welding material for fusion welding butt joint transition layers of titanium-steel composite plates, and also relates to a preparation method of the welding material. Background technique [0002] Titanium-steel explosive rolling clad plate is a new bimetal structure composite material, which combines the advantages of titanium and steel, and has both the excellent corrosion resistance of titanium and the high strength and toughness of steel. In recent years, the composite panel has been gradually reused in core large pressure vessels and oil and gas transportation pipelines, which not only solves the problem that a single steel is easily corroded, but also solves the problem of high cost of using a single corrosion-resistant material. However, due to the large difference in physical and chemical properties of titanium and iron elements, highly brittl...
