Tig Welding a waterwall tube.

Over 50% of the root pass can be welded without removing the tube clamp. Without having to tack weld the tube first, one side of the tube can be welded with only one tie in. This will greatly reduce the chances of a rejected radiograph for incomplete or excessive penetration.
