Modern induction heating provides reliable, repeatable, non-contact and energy-efficient heat in a minimal amount of time. Modern induction heating systems are capable of heating very small areas within precise production tolerances, without disturbing individual metallurgical characteristics of brazed components. For larger volume applications and/or quality-dependent processes, parts can be brazed with induction under a controlled atmosphere without flux or any additional cleaning steps. Typical MF power supplies for induction brazing range from 1 to 100kW, depending on the parts and application requirements
Brazing in a controlled vacuum or in an inert protective atmosphere can significantly improve overall part quality and eliminate costly part cleaning procedures.
Brazing by flame in a normal oxygen atmosphere can cause oxidation, scaling and carbon buildup on the parts. To clean the parts, applications of joint weakening flux or expensive acid cleaning baths are often required.
