[0051] The preparation method of powder for laser cladding, the specific steps are as follows:
[0052] Step 1: Weigh 40% of Cu powder, 20% of V powder, 20% of Ni powder, 10% of Ag powder, and 10% of B powder according to mass percentage, and the sum of the mass percentages of the above components is 100%;
[0053] Step 2: Mix the powders of the raw materials in step 1, vacuum melt them, and use gas atomization to make powders; wherein, N 2 As an atomizing gas, the atomizing pressure is 6-8MPa, and the superheat of the melt is kept between 100 and 150°C during the atomizing process;
[0054] Step 3: performing particle size screening on the atomized alloy powder, so that the screened alloy powder is within the particle size range of 25-53 μm;
[0055] Step 4: vacuum pack the prepared powder for use.
[0056] The preparation method of copper-based flux-cored welding wire for TIG welding, the specific steps are as follows:
[0057] Step 1: Weigh 20-30% of Ag powder, 15-25% of...
