Roll seam welding apparatus, useful for producing profile component e.g. endless profile, includes welding unit having pair of roll-shaped welding electrodes provided for welding components, and movement mechanism coupled to welding unit

摘要

The roll seam welding apparatus comprises a first welding unit (1) comprising a pair of roll-shaped welding electrodes (10) provided for welding components (8) provided between the electrodes, and a movement mechanism coupled to the first welding unit. The welding electrodes are applied with a welding current. The first welding unit is movable transverse to the insertion direction of the components to be welded using the movement mechanism during the generation of a roll weld seam. The first welding unit is rotatably or pivotably coupled to the movement mechanism via a steering mechanism. The roll seam welding apparatus comprises a first welding unit (1) comprising a pair of roll-shaped welding electrodes (10) provided for welding components (8) provided between the electrodes, and a movement mechanism coupled to the first welding unit. The welding electrodes are applied with a welding current. The first welding unit is movable transverse to the insertion direction of the components to be welded using the movement mechanism during the generation of a roll weld seam. The first welding unit is rotatably or pivotably coupled to the movement mechanism via a steering mechanism so that an extending direction of the pair of roll-shaped welding electrodes is changed during the generation of the roll weld seam. The roll seam welding apparatus further comprises a control unit. The control unit is arranged to the steering mechanism such that a running direction of the welding electrodes is guided in a welding direction by a first roller unit for producing the weld seam. The movement of the first welding unit is controlled by a drive mechanism and by detecting the current position of the components to be welded. The first welding unit further comprises a supply unit, which is adapted for generating a supply rate of the components to be welded. The supply unit includes drive rollers that are mounted on the same axis as the welding electrodes of the first welding unit. One of the welding electrodes of the first welding unit is driven by a drive. An independent claim is included for a profile component made from the components by forming and roll seam welding a component.
