Abstract

The present invention relates to a device (10) for the inductive heating of metallic structural elements (16, 18), in particular structural elements of a gas turbine, using at least one induction generator. The device (10) comprises at least two induction coils (12, 14) which are independent in design, wherein at least one of the induction coils (12, 14) can be moved in the direction of the structural elements to be heated (16, 18) so that the structural elements to be heated (16, 18) come to rest between the induction coils (12, 14), the latter (12, 14) forming a common working space (20). The invention further relates to a method for the inductive heating of metallic structural elements, in particular structural elements of a gas turbine.
