Abstract

The method involves suspending an electrically conducting, laminar structure (4) to an electromagnetic field in such a manner that structure is heated within the area of the dents (2) and electromagnetic force is practiced by the electromagnetic field on the dents to cause a deformation of the dents over the smooth condition of the structure. The electromagnetic field is repealed for the cooling and relaxation of the structure within the area of the dents. A magnetic field producer (6) is consulted with an electrical generator (8) for the production of electromagnetic field. An independent claim is included for a device for removing dents from an electrically conducting, laminar structure.
