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 INDUCTIONCONDUCTORS WHICH ARE SEPARABLE FROM ONE ANOTHER

摘要

The invention relates to a method for the inductive radiofrequency welding of metal products, in which the edge regions to be welded of the metal products are heated by inducing radiofrequency currents with the use of at least one induction conductor, the metal products and a welding zone are moved relative to one another, the edge regions to be welded are brought in contact in the welding zone and are welded together to form a weld seam. The invention furthermore relates to a device for the inductive radiofrequency welding of metal products, having means for carrying out a relative movement between the metal products and a welding zone, as well as at least one induction conductor which heats the edge regions to be welded of the metal products by inducing radiofrequency currents. The object of proposing a generic inductive radiofrequency welding method and a corresponding generic inductive radiofrequency welding device, with which metal products with different material thicknesses and/or material properties can be welded together reliably in processing terms, is achieved according to the method in that an induction conductor is used which consists of at least two mutually separable induction conductor components that are assigned to the respective metal product and are adapted thereto, and the heating of the edge regions to be welded is adjusted separately for the respective metal product.
