Example Embodiment
[0022] Example one
[0023] Such as Figure 1 to Figure 2 As shown, the resistance heating and ultrasonic vibration composite heating brazing method of precision parts includes the following steps:
[0024] (1) A solder sheet 3 is preset on the surface of the parent workpiece 2 to be welded. The material of the solder sheet 3 is Ag30CuZn, and the thickness of the solder sheet 3 is 3mm;
[0025] (2) Place the welded matrix workpiece 2 on the resistance heating positive and negative electrodes 1a, 1b, and the two electrodes are arranged side by side, leaving a gap of 0.1mm between the positive and negative electrodes 1a, 1b;
[0026] (3) Mount the base workpiece 4 to be welded, and adjust the fixture 5 so that the surface to be welded on the base workpiece 4 to be welded is directly above the solder sheet 3;
[0027] (4) Start the ultrasonic vibrator pressure device, start to adjust the height of the ultrasonic vibrator 6, and press the base workpiece 4 to be welded, so that the base wor...
Example Embodiment
[0036] Example two
[0037] Change the Ag30CuZn solder sheet in the first embodiment to Ag45CuZnCd solder sheet, and the rest are the same as the first embodiment.
Example Embodiment
[0038] Example three
[0039] The solder sheet in Embodiment 1 or Embodiment 2 is surfacing welded on the surface to be welded of the parent workpiece to be welded, and the rest remains unchanged.
