A client came to THE LAB at Ambrell looking to braze carbide cutting tips to drill bits ranging in size from 0.5" to 1.5" (12.7 to 38.1 mm) in diameter. The brazing takes place at 1900 °F (1038 °C) and was done in 11 seconds for the 0.5" diameter bit and 39 seconds for the 1.5" (38.1 mm) diameter bit. The client's objectives include decreasing the brazing times, especially for the larger drill bits. Repeatability must also be adequate. 

A valve manufacturer that was using a torch to braze several different copper and brass assemblies came to THE LAB at Ambrell to consider making the switch to induction heating. THE LAB determined that an Ambrell EASYHEAT^TM 10 kW, 150-400 kHz induction power supply would be the best system for their requirements. Multiple custom-designed single position multiple-turn coils were built to generate the required heating for this brazing application.

A client came to THE LAB at Ambrell looking to braze steel fittings and tubes within a targeted heating time of under 150 seconds to make hydraulic fittings. THE LAB determined that an Ambrell EKOHEAT^® 15 kW, 50-150 kHz induction power supply would best meet their requirements. A custom-designed single position multiple-turn helical coil was built to generate the required heating for this brazing application. 

A client came to THE LAB at Ambrell looking to braze both ends of a steel assembly concurrently. They were familiar with induction heating and already had processes set up in their facility, but this was a new process that they wanted to design. Speed and repeatability were two particularly important factors to the client. They needed to heat the part to 1425 °F (774 °C) within one minute.
