Abstract
A magnetic forming system (10) for creating a fluid circuit joint between a tube and a fitting includes an induction coil (12). The induction coil (12) may form a first stage electromagnetic current. A field concentrator (132) may focus the first stage electromagnetic current to form a second stage electromagnetic current. An insert (136) may focus the second stage electromagnetic current to form an electromagnetic field. The electromagnetic field forms the fluid circuit joint. The induction coil (12) may be insertable within the tube, generate an electromagnetic field, and impose the electromagnetic field on and to expand a portion of the tube within the fitting to form the fluid circuit joint. The system (10) may include a receptacle (54) that is external to the tube and the fitting. An insert (56) may be mechanically coupled within the receptacle (54) and limit the outward expansion of the tube and the fitting.
