A welding arrangement is described for the permanent joining of a first tubular component with a second component along a two- or three-dimensional intersection curve, along which both components touch, with a fastening arrangement for detachably fixed joining to a tubular end of the first component facing away from the intersection curve - Or directly to the mounting assembly about a first component associated with the pipe longitudinal axis pivotally mounted manipulator unit with a freely positionable end of the manipulator, and a mounted on the freely positionable manipulator end welding tool. The invention is characterized in that the fastening arrangement comprises a clamping module which can be inserted at least partially axially into the tubular end of the first component and which is designed for releasably fixed joining to a tube inner wall assigned to the first tubular component, and to a carrier ring module rotatably mounted on the clamping module , which in the assembled state of the clamping module projects axially beyond the tubular end of the first component and is operatively connected to a servomotor for rotationally driving the carrier ring module about the tube longitudinal axis, so that the carrier ring module is mounted so as to be infinitely rotatable about the tube longitudinal axis. Furthermore, at least one linear support structure is mounted on the support ring module, which is mounted bidirectionally deflectable by means of an actuator parallel to the tube longitudinal axis, and that the manipulator unit is attached to one end of the structure. |
