Overall welding method:

For motors with diameters less than 800, integral welding is used. The heating method adopts the lower heating mode, the inductor is located at the lower part of the end ring to be heated, and the end ring is stationary when heated, and the specific process is: locating the end ring of the motor to be welded from the preparation process to the sensor of the brazing machine tool, The motor rotor is then hoisted to the brazing machine (or the end ring and motor rotor are pre-assembled) so that the clearance between the end ring and the rotor bar meets the weld clearance requirements. Start adding solder and flux, solder and flux, and then start soldering according to heating and insulation requirements. After the welding is finished, the rotor is suspended, and then the other end is welded by the same process.

Segment welding method:

     For motors with diameters greater than 800, segmented welding is used. The heating method adopts the lower heating mode, the inductor is located at the lower part of the end ring to be heated, and the end ring is stationary when heated, and the specific process is: locating the end ring of the motor to be welded from the preparation process to the sensor of the brazing machine tool, The motor rotor is then hoisted to the brazing machine (or the end ring and motor rotor are pre-assembled) so that the clearance between the end ring and the rotor bar meets the weld clearance requirements. Start adding solder and flux, solder and flux, and then start soldering according to heating and insulation requirements. After the welding is finished, the machine rotates the workpiece to the next welding position and then heats the welding again. This is repeated until the entire end ring is welded. After the welding is completed, the rotor is suspended, and then the other end is welded by the same process.
