A method and a device for inductive radiofrequency welding of metal products, include heating by inducing radiofrequency currents with use of at least one induction conductor. The metal products and a welding zone are moved relative to one another, so that edge regions of the metal products to be welded are brought in contact in the welding zone and are welded together to form a weld seam. Metal products with different material thicknesses and/or material properties can be welded together because an induction conductor which heats the edge regions of the metal products is used which includes at least two mutually separable induction conductor components that are assigned to the respective metal product and are adapted thereto, and the edge regions to be welded are heated in a manner that is adjusted separately for the respective metal product.

Method and apparatus for the inductive high-frequency welding of metal products having different material thicknesses and/or material grades using at least two component induction conductors which are separable from one another

A transversal field heating installation for inductively heating flat objects transported in an advancing direction includes at least one inductor unit that extends across the width of the flat object. The inductor unit has at least two superimposed inductor layers parallel to the plane of the flat object. These inductor layers can be independently displaced transversally in relation to the advancing direction of the flat object, and each have two inductor sections with two parallel interspaced base limbs extending transversally in relation to the advancing direction and one lateral limb. Each inductor layer has lateral limb per strip edge of the flat object. The inductor sections of an inductor layer can be independently displaced transversally in relation to the advancing direction of the flat object.
