Induction brazing is a metal joining process that generates heat in base metals via electromagnetic induction to liquefy and flow a filler metal into the joint gap. Induction brazing creates very strong joints without melting the workpieces together.

Key Features:

• Localized Heating: The heat is generated only where the joint is located, which minimizes distortion and thermal loss.
• Clean and Accurate Joints: When brazing with no direct flame, there is little oxidation to contend with, and the brazing process produces clean (typically) and accurate joints.
• Fast and Repeatable: Due to the speed of the process and, in particular, the automated induction brazing process, where speed and accuracy each work in harmony, induction brazing is common in high-production manufacturing.

Induction brazing is used in many industries, such as aerospace, electronics, HVAC, and automotive, where cleanliness and accuracy are critical. An example of these are induction-brazed copper pipes used in air conditioning units or steel components in automotive fuel systems. The induction brazing process is fast and is tightly defined, which meant high-quality joints were made in less time with little to no post-processing. It also accommodates a large subset of filler metals comprising silver, copper, and nickel alloys, which is advantageous across different material types.
