specific Embodiment approach 1
[0004] Specific Embodiment 1: In this embodiment, the method for brazing aluminum alloys at low temperature to obtain high-temperature serviceable welded joints is realized through the following steps: 1. The brazing filler metal is made into thin slices of 50-500 μm or rods or wires with a diameter of 1000-5000 μm Put it into the weld gap of two parts to be welded or the gap port; 2. Under the conditions of ultrasonic frequency of 20-100kHz, amplitude of 1-50μm, and brazing temperature of 190-450℃, perform ultrasonic brazing on the brazing part Weld for 0.1-60s, complete the preliminary brazing and form a welded joint at the welding place; 3. Adjust the temperature of the welded joint to 190-550°C and keep it for 1-60 minutes, and then use ultrasonic frequency of 20-100kHz and amplitude of Ultrasonic vibration is carried out on the welded joint under the condition of 1-50 μm, that is, the method of realizing low-temperature brazing aluminum alloy to obtain high-temperature per...
specific Embodiment approach 2
[0006] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, the solder for brazing aluminum alloy at low temperature is a Sn-Zn alloy, Zn-Al with a mass percentage of Zn of 50% to 99.99%. One of alloy or pure zinc. Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0007] Specific embodiment three: the difference between this embodiment and specific embodiment one is that in step one, the brazing material is made into a thin sheet of 100-400 μm or a rod or wire with a diameter of 2000-4000 μm is put into the welding of two parts to be welded. slot gap or gap port. Other steps are the same as in the first embodiment.
