Abstract Apparatus for assembling flanges to waveguides which utilizes electromagnetic forming means for producing the bond between the waveguide and the flange assembly. The flange assembly includes a collar portion which is mounted about the waveguide adjacent the end thereof and a flanged portion extending from the collar portion. A tapered mandrel is inserted in the waveguide and the electromagnetic forming device is mounted around the collar of the flange assembly and energized for application of a magnetic field across the flange collar and waveguide. A primary varying magnetic field is generated which is which is inductively linked with the workpiece, in this case, the flange collar. The primary varying field induces eddy currents in the collar and the eddy currents create a secondary magnetic field which interacts with the primary field to produce a high uniform pressure which swages the flange assembly against against the waveguide. The mandrel prevents collapse of the flange collar and waveguide during the assembly and is removed subsequent to completion of the assembly.
Apparatus for assembling flanges to waveguides comprising: a. a flange assembly including a collar having a flanged portion extending therefrom; b. a core element adapted for insertion into said waveguide; c. electromagnetic forming means carried about said collar of said flange adjacent said flanged portion thereof, said forming means disposed for energization for applying a work force between said core element and said neck for swaging said flange collar to said waveguide.
