[0043] The present invention also provides a preparation method of the welding wire for the above-mentioned TA1-Cu-Q345 transition layer, and the specific steps are as follows:
[0044]Step 1: Weigh 40-50% of V powder, 30-40% of Co powder, 5-10% of Si powder, and 5-10% of B powder according to mass percentage, and the sum of the mass percentages of the above components is 100%; step 1 Among them, the purity of V powder is ≥99.9%, the purity of Co powder is ≥99.9%, the purity of Si powder is ≥99.9%, the purity of B powder is ≥99.9%, and the particle size of the four powders is 200 mesh.
[0045] Step 2: Place the V powder, Co powder, Si powder and B powder weighed in step 1 in a vacuum heating furnace to heat and keep warm to remove the crystal water in the powder; place the dried powder in a powder mixer for Fully mix; in step 2, the heating temperature in the vacuum heating furnace is 180°C, and the holding time is 2h; the mixing time in the powder mixer is 40min;
