[0025] The preparation method of the above-mentioned Ag-V welding wire for welding the titanium-pipeline steel composite plate, the specific steps are as follows:
[0026] Step 1, put the V powder in a vacuum heating furnace at 200°C and bake for 2.5 hours to remove the crystal water in the V powder; the purity of the V powder is 99.99%, and the particle size is 80-100 mesh;
[0027] Step 2, put the dried V powder into a reagent bottle with a rubber stopper, insert one end of the pure silver tube into the reagent bottle through the rubber stopper, close the other end of the pure silver tube, then shake the reagent bottle upside down, Put the V powder into the pure silver tube, and control the filling amount of the V powder to be 10% to 20%;
[0028] Step 3: Shake the pure silver tube containing the V powder horizontally for 1-2 minutes, so that the V powder is evenly spread in the pure silver tube, and finally draw it to obtain an Ag-V welding wire with a diameter of 1.2mm.

[0030] Step 1, put the V powder in a vacuum heating furnace with a temperature of 200°C and bake for 2.5 hours to remove the crystal water in the V powder; the purity of the V powder is 99.99%, and the particle size is 80 mesh;
[0031] Step 2, put the dried V powder into a reagent bottle with a rubber stopper, insert one end of the pure silver tube into the reagent bottle through the rubber stopper, close the other end of the pure silver tube, then shake the reagent bottle upside down, Make the V powder enter the pure silver tube, and control the filling amount of the V powder to be 10%;
[0032] Step 3: Shake the pure silver tube containing the V powder horizontally for 1 min, so that the V powder is evenly spread in the pure silver tube, and finally draw it to obtain an Ag-V welding wire with a diameter of 1.2mm.
