Induction Rapid Brazing
Induction rapid brazing heats the joint zone with high-frequency electromagnetic energy in seconds. This minimizes thermal distortion and prevents weld wear.
Physical-Chemical Working Mechanism
Induction rapid brazing uses high-frequency electromagnetic alternating fields to heat the joint zone quickly and locally. The energy is converted into electrical currents in the metal, which heat it.
Metallurgical Relevance & Welding Risks
This process is especially suitable for delicate parts because it allows rapid cooling and causes minimal thermal stress. However, too fast cooling can lead to glass-hard martensite, which causes cracks and impairs toughness. Cooling too long coarsens the grain and reduces strength.
Workshop Practice & Action Items
Use induction rapid brazing for delicate parts or when processing time is short. Make sure the frequency and heating time are set correctly. A typical cooling time is 1 to 2 seconds. Always monitor the temperature and the weld structure.
