Brazing processes allow metals to be soldered together using filler material. Traditional brazing systems, based on the manual use of oxyacetylene flames, do not guarantee the repeatability and quality of the soldering as it depends above all on the skill and experience of the operator.
We have worked with several customers to innovate brazing processes and to eliminate the risks of using gas in cylinders in production plants by introducing induction brazing technology.
In particular, at InovaLab we have designed the inductors as well as optimized the process recipes – times, power, pressures – through the use of multiphysical, electromagnetic and thermal models, which allow to accurately predict the behavior of the objects to be soldered during the heating process. In addition, we have developed inductors and their generators for use in prototypes in order to validate simulation results and refine the designs before the actual construction of industrial machinery.
Thanks to Inovalab’s research, customers were able to substitute some traditional flame brazing processes with induction brazing processes that use a controlled temperature and offer high quality standards that do not depend on the operator’s manual skills.
The adoption of induction heating has benefits beyond energy efficiency: it eliminates the use of flammable gases and reduces the risks related to gas storage at production sites.
