Welding assembly for permanent joining of a first tubular component with a second component

A welding assembly for permanent joining of a first tubular component with a second component along a two or three-dimensional intersection curve, along which the components contact, comprising:

• a securing assembly for detachably securely joining a tubular end of the first component facing away from the intersection curve to a manipulator unit which is attached to the securing assembly to pivot about a longitudinal axis of the first component, the manipulator unit having a freely positionable manipulator end, and a welding tool attached to the freely positionable manipulator end, the securing assembly comprising a clamping module which is at least partially introducible into the tubular end of the first component on an end side in an axial manner, the clamping module being detachably securely joined onto a tube inner wall of the first tubular component, and to a carrier ring module which is rotatably attached to the clamping module, the carrier ring module axially extending beyond the tubular end of the first component when joined to the clamping module, and which is operatively coupled to a servomotor for the rotary driving of the carrier ring module about a tube longitudinal axis so that the carrier ring module is rotatable continuously about the tube longitudinal axis, and at least one linear frame attached to the carrier ring module, which is mounted to be movable bidirectionally and parallel to the tube longitudinal axis by an actuator, wherein
• the manipulator is a 6-axis open kinematic chain having a vertically articulated robot and is attached to one end of the frame;
• and
• a supply module on which is attached at least one of a control unit, an electrical energy supply unit, and at least one reservoir for material relating to a welding process and the material comprising welding wire and process gas;
• the at least one component is connected to the welding tool via a connection line;
• the supply module is rotatably mounted for performing a rotational movement when the movement from the welding tool occurs about the tube longitudinal axis, which permits rotations of the welding tool about the tube longitudinal axis;
• and
• the supply module is connected so to be positionable along at least one plane or the supply module is connected to the carrier ring module in a rotatably fixed manner.
