An induction heating system can be adapted for shrink fitting a plurality of different assemblies. A plurality of tooling units associated to respective ones of the assemblies, each one having an appropriately configured induction coil and holder, can be provided. A computer can be used to control the delivery of electrical power to the induction coil in accordance with a heating recipe, and can be provided with an input device for inputting an assembly identifier allowing the computer to operate the control based on the right heating recipe.

System and method for induction shrink fitting

A method of reforming an annular attachment flange of an outer annular portion of a gas generator case, including inserting a first fixture element within the annular portion, the first fixture element conforming to an inner surface of the flange and forcing the flange radially outwardly passed a desired orientation, pressing the attachment flange against the first fixture element with a second annular fixture element surrounding the flange and conforming to an outer surface of the flange, heating the outer portion pressed by the fixture elements to a temperature and time period corresponding to an annealing of the material of the outer portion, forcing cooling of the outer portion, and disengaging the cooled outer portion from the fixture elements so that the released flange extends at the desired orientation. A gas generator case including a reformed outer portion and an unused inner portion is also discussed.
