How does induction brazing work?

Induction brazing is a process that uses electromagnetic induction to heat a metal workpiece to melting temperature. The brazing filler metal, which is usually a lower melting point alloy, is then flowed into the gap between the two workpieces. The molten filler metal wets the surface of the workpieces and creates a strong metallurgical bond when it solidifies.

What are the benefits of induction brazing?

Induction brazing offers several benefits compared to traditional methods such as torch brazing or furnace brazing. One of the main advantages is the precise and localized heating that induction provides. This results in minimal heat distortion to the workpiece and reduces the risk of overheating delicate components. Additionally, induction brazing is a fast and efficient process, with heating and cooling times typically much shorter than other methods. The process is also easily automated, making it ideal for high volume production.

What materials can be brazed using induction brazing?

Induction brazing is versatile and can be used to join a wide range of metals and alloys, including stainless steel, carbon steel, copper, brass, and aluminum. This makes it a popular choice for industries such as automotive, aerospace, and electronics, where dissimilar materials often need to be joined together.
