Induction Shrink Fitting: Copper Ring into an Aluminum Casting
Objective Shrink fitting is a mechanical joining process that creates an extremely tight, permanent joint by intentionally making an outer part...
A client had been brazing a nickel pin and a braided nickel wire with a torch. They turned to THE LAB at Ambrell to recommend a process for brazing with induction heating. The client wanted to take advantage of induction's benefits, including repeatability, safety and speed. The end product from this application is a heater assembly.
THE LAB determined that an Ambrell EASYHEATTM 2.4 kW, 150-400 kHz induction heating system would be the right system for their requirements. They designed a single position multiple-turn U-coil for this application. Testing showed it takes 25 seconds to heat the assembly and create a brazed joint, which met the client's requirements.
When compared to torch heating, repeatability is a key benefit. With a torch, you're dependent on the operator's skill, whereas with induction you get the same result every time. Safety is another considerable benefit, as there's no open flame in the work environment. And, of course, induction is a fast, precise heating method that requires a minimal footprint.
