Preferably, the method comprises the following steps: the blade is milled on the wheel disc, wherein the blade is milled on the wheel disc in a mode of combining semi-open type and closed type, and the wheel disc is annularly connected with the wheel cover through manual sub-arc welding. The wheel cover and the blades are connected together through brazing.
The invention relates to a method for manufacturing a narrow-runner binary working wheel used on a turbine compressor, which comprises the following steps:
1) the partial runners at the outlet are milled integrally according to a closed impeller, so that the size of the outlet completely meets the design requirement, the rest runners are milled according to an open impeller method, and the runner of the impeller is completed by a five-axis five-linkage machine tool;
2) after the fit clearance of the composite wheel disc wheel cover reaches 0-0.01 mm, the clearance of the inlet runner side is 0.05 mm;
3) inlaying gold-based brazing filler metal at the blade brazing position, and then putting the blade brazing filler metal into a vacuum brazing furnace to complete impeller brazing;
4) turning a turning machine to remove unnecessary brazing layers in the annular welding seam area;
5) welding a wheel disc and a wheel cover annular area by manual argon arc welding;
6) heat treatment solid solution aging (or quenching and tempering);
7) carrying out dye check on the impeller;
8) turning the whole appearance;
9) overspeed of the impeller;
10) performing dye check and cleaning;
11) and (6) integrally inspecting and warehousing.
The invention cancels the original wheel disc of the impeller and rivets for compounding the wheel cover, mills the blade on the wheel disc in a way of combining the semi-open type and the closed type of the blade, and then adopts 'braze + ring' welding to compound the wheel disc and the wheel cover into a whole; the novel flow channel welding device has the characteristics of sufficient welding strength, smooth flow channel welding transition area, small unbalance amount, good appearance quality and the like, so that the product efficiency is improved, and the requirements of European markets are met.

The invention relates to a method for manufacturing a narrow-runner binary working wheel used on a turbine compressor, which comprises the following steps:
1) the partial runners at the outlet are milled integrally according to a closed impeller, so that the size of the outlet completely meets the design requirement, the rest runners are milled according to an open impeller method, and the runner of the impeller is completed by a five-axis five-linkage machine tool;
2) after the fit clearance of the composite wheel disc wheel cover reaches 0-0.01 mm, the clearance of the inlet runner side is 0.05 mm;
3) inlaying gold-based brazing filler metal at the blade brazing position, and then putting the blade brazing filler metal into a vacuum brazing furnace to complete impeller brazing;
4) turning a turning machine to remove unnecessary brazing layers in the annular welding seam area;
5) welding a wheel disc and a wheel cover annular area by manual argon arc welding;
6) heat treatment solid solution aging (or quenching and tempering);
7) carrying out dye check on the impeller;

9) overspeed of the impeller;
10) performing dye check and cleaning;
11) and (6) integrally inspecting and warehousing.
The blade of the invention is milled on the wheel disc, and the joint of the wheel disc and the wheel cover is provided with a melting groove to prevent the brazing filler metal from entering a manual electric arc welding area, and in case that the brazing filler metal is melted in the electric arc welding area, the blade is turned on a lathe to remove the melted brazing filler metal, and the thickness of the blade is about 2 mm. During manual electric arc welding, argon shield welding is preferably adopted, and welding forming failure caused by blooming due to hydrogen fusion in the welding process is prevented. The manufacturing process of the invention finally compounds the wheel disc (including the blades) and the wheel cover into a whole through 'brazing + annular' welding, accords with the original design concept from the dimensional requirement, and obviously improves the appearance quality.
