摘要

The device for connecting a ribbed tube (3, 5) with an isosceles-curved tube by using a welding seam, where the ribbed tube is fixedly clamped and the curved tube is fixed relative to the ribbed tube, comprises a welding nozzle (2), by which the welding seam is introduced for connecting the tubes. The ribbed tube is rotatably clampable in a clamping device around its longitudinal axis. The welding nozzle is fixed at the end of a supporting arm (1). The supporting arm is pivotable around the axis of the welding nozzle (7). The pivotation of the supporting arm takes places around 180[deg] . The device for connecting a ribbed tube (3, 5) with an isosceles-curved tube by using a welding seam, where the ribbed tube is fixedly clamped and the curved tube is fixed relative to the ribbed tube, comprises a welding nozzle (2), by which the welding seam is introduced for connecting the tubes. The ribbed tube is rotatably clampable in a clamping device around its longitudinal axis. The welding nozzle is fixed at the end of a supporting arm (1). The supporting arm is pivotable around the axis of the welding nozzle (7). The pivotation of the supporting arm takes places around 180[deg] from a point, which lies vertical to the rotation axis of the ribbed tube. The pivoting plane of the supporting arm lies vertical to the axis of the welding nozzle. The supporting arm is horizontally arranged and the welding nozzle seated at the supporting arm assigns vertically downward. The supporting arm of the welding nozzle is formed as shank of a U-shaped holder and the holder is pivotably mounted around the axis of the welding nozzle. The lower shank of the holder is formed as supporting arm of the welding nozzle. The clamping device is provided for clamping two tubes arranged parallel to each other. The clamping device carrying the tubes is rotatable around the axis of the one of the tubes, where the curved tube is directly welded to the ribbed tube. An independent claim is included for a method for operating a device.
