Magnetic field concentrator for electromagnetic forming
First Claim
1. A magnetic forming system for creating a fluid circuit joint between a tube and a fitting comprising:
- an induction coil forming a first stage electromagnetic current;
a field concentrator electrically coupled to said induction coil and focusing said first stage electromagnetic current to form a second stage electromagnetic current; and
an insert electrically coupled to said field concentrator and focusing said second stage electromagnetic current to form an electromagnetic field, said electromagnetic field forming the fluid circuit joint.

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.
