Induction Soldering Brass and Copper Components

A customer contacted THE LAB at Ambrell because they were soldering brass and copper components with a torch, but wanted to see if induction might be a faster, more repeatable heating method for their process. THE LAB determined that an Ambrell EASYHEAT 10 kW, 150-400 kHz induction heating power supply with a custom-designed four-position multiple-turn helical coil would meet their objective.

Initial tests were conducted to optimize the power delivered to the assembly. Temperature indicating paints were used to determine the time to temperature. A solder wire preform was placed on the part to allow for repeatable placement of solder in every joint. Four tops or four bottom joints can be heated at one time within 2-3 minutes for this soldering application.

Induction heating offered this customer several critical benefits. First, the client was able to solder their parts quickly, meeting their time objective. Induction is also highly repeatable, which ensures part quality. It's also a very precise heating method, meaning only the portion of the part that requires heating gets heated. In regards to safety, there is no open flame with induction heating. Finally, the expertise of THE LAB allowed the client to have peace-of-mind of knowing their application would work prior to investing in induction equipment. 

If you have a soldering application you'd like assessed by our induction heating application experts, contact THE LAB to take advantage of free application testing. We'll send your parts back for inspection, along with passing along a video showing you the heating process. You can even view it live with our Remote Lab Service or visit our facility to observe testing in person.
