Abstract
A device for connecting the ends of pipes, which are aligned, tack-welded and made of steel, by an orbital welding process using a welding joint formed by the pipe ends and using tools which can be orbitally moved about the welding joint for welding and checking the seam. The device includes guide base plates placed on both sides at each pipe end in the region of the welding joint and rigidly clamped to the pipe ends. The guide base plates centrally have a circular recess with a radial opening for the feed-through of the pipes to be welded. The guide base plates include clamping elements rigidly connected to each guide base plate face facing away from the welding joint, and a frame for receiving the welding and checking tools, the frame rotatably mounted between the guide base plates and centrally pivotal about the pipe ends by at least 360°.
