Soldering/brazing is a process in which two or more identical or different materials are joined by means of another metal alloy with a lower melting point. Induction heating is the ideal technology for soft soldering and hard soldering, due to reliability, reproducibility, contact-free transfer of energy, high energy efficiency, flameless. Heat is generated in a very short time, where very small areas can be selectively heated within precise product tolerances without disturbing individual metallurgical characteristics. hard soldering or soft soldering by means of induction heating can be done under controlled atmosphere (vacuum / protective gas) without flux or any extra cleaning steps. Standard induction heating systems for hard soldering range from 1 to 40kW.
Connections made with brazing can be made exceptionally strong, sometimes stronger than the two connected metals themselves.
Connections made with brazing:
- are liquid and gas tight.
- are resistant to shocks and vibrations.
- are insensitive to normal temperature changes.
- provide good electrical conduction and can be galvanized with conventional processes.
Standard brazing temperatures vary between 425 ° C and 1180 ° C.
