Embodiment 1
[0023] Such as Figure 1 to Figure 2 As shown, the resistance heating and ultrasonic vibration composite heating brazing method of precision components includes the following steps:
[0024] (1) Preset a solder sheet 3 on the surface of the workpiece 2 to be welded, the material of the solder sheet 3 is Ag30CuZn, and the thickness of the solder sheet 3 is 3 mm;
[0025] (2) Place the workpiece 2 to be welded on the positive and negative electrodes 1a and 1b of resistance heating, arrange the two electrodes side by side, and leave a gap of 0.1 mm between the positive and negative electrodes 1a and 1b;
[0026] (3) clamp the base workpiece 4 to be welded, and adjust the fixture 5 so that the surface to be welded of the base workpiece 4 to be welded is located directly above the solder sheet 3;
[0027] (4) Start the ultrasonic vibrator pressure device, start and adjust the height of the ultrasonic vibrator 6, and press the welded base workpiece 4 so that the welded base workpie...
Embodiment 2
[0037] Change the Ag30CuZn solder sheet in Embodiment 1 to Ag45CuZnCd solder sheet, and the rest are the same as Embodiment 1.
Embodiment 3
[0039] The solder sheet in the first or second embodiment is surfacing welded on the surface to be welded of the parent workpiece to be welded, and the rest remain unchanged.
