What should be paid attention to when induction brazing dissimilar metals?

Induction brazing dissimilar metals requires special attention to the following matters:

1. Metal compatibility: Ensure that the selected dissimilar metals are compatible in chemical composition and properties to avoid adverse reactions or unstable induction brazing.

2. Material preparation: Make sure the metal surface to be joined is smooth and clean, and remove grease, oxides and other dirt to ensure good induction brazing quality.

3. Filler metal: Choose the appropriate filler metal to ensure a good connection. The choice of filler metal should take into account the chemical composition and properties of the two metals.

4. Temperature control: During the induction brazing process, the temperature needs to be controlled to ensure that it does not cause unnecessary thermal damage or deformation. A reasonable temperature is the key to success.

5. Design of induction coil: Design induction coil reasonably to ensure the production of appropriate induction heating brazing mode. This takes into account the size, shape, and location of the metal.

6. Heating parameters: Precisely control the parameters of induction heating, including current, frequency and time. These parameters should be adjusted according to the specific metal type and welding requirements.

7. Shielding gas: In the induction brazing process, use appropriate protective gas, such as inert gas, to reduce oxidation and pollution. This helps to maintain the quality of the weld.

8. Welding Process: Follow the correct induction brazing process steps, including preheating, welding, and cooling, to ensure a stable connection.

9. Quality control: control the quality of induction brazing, including weld seam and non-destructive inspection, to ensure that the quality meets the standard.

10. Safety: Take necessary safety measures, including wearing personal protective equipment and following relevant safety guidelines, to prevent accidents.

Induction brazing of dissimilar metals requires specialized knowledge and skills, so it is best performed by experienced professionals to ensure welding quality and safety.
