Estimating the term…
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 for inductive radiofrequency welding of metal products, in which edge regions to be welded of the metal products are heated 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, the edge regions to be welded are brought in contact in the welding zone and are welded together to form a weld seam, wherein an induction conductor is used which comprises at least two mutually separable induction conductor components that are assigned to a respective metal product and are arranged relative thereto, and the edge regions to be welded are heated up, by induced radiofrequency current and a trajectory of the induced radiofrequency current in the metal product, to a welding temperature by each mutually separable induction conductor component in a manner that is adjusted separately for the respective metal product.
Device for 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 edge regions to be welded of the metal products by inducing radiofrequency currents, wherein the induction conductor comprises at least two separable induction conductor components that are assigned to the respective metal product and are arranged relative thereto, so that the edge regions to be welded of the respective metal products are heated up, by induced radiofrequency current and a trajectory of the induced radiofrequency current in the metal product, to a welding temperature by each mutually separable induction conductor component in a manner that is adjustable separately from one another.
