Induction Brazing Energy Input
Induction brazing heat input is a targeted, non-contact heating of the joint area using an electromagnetic alternating field for short cycle times and minimal heat distortion. It allows precise temperature control.
Physical-Chemical Mechanism of Action
Induction brazing heat input uses an electromagnetic alternating field that moves the electrons in the metal, thereby introducing energy. This leads to rapid heating of the joint area without direct contact with a heat source.
Metallurgical Relevance & Risks in Welding
Precise temperature control enables optimal deformation and bonding of the metals. However, too high heat input can cause overheating, leading to distortion or even melting of the joint area. Too low heat input prevents proper bonding and can result in weak spots in the weld.
Workshop Practice & Instructions
Use an induction brazing system with correctly set frequency and power. Continuously monitor the temperature of the joint area and adjust the heat input accordingly. A typical cycle time is 0.5 to 1 second per cm² of joint area.
