  • 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
    Patent number: 9884387
    Abstract: 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.
