    • A movable backing system enables it to continuously, easily perform full penetration welding along a weld line in a confined space, irrespective of the length, configuration and other factors of a weld zone. A weld backing, which has a backing member disposed on the side facing a workpiece and cooling means disposed inside the weld backing for cooling the backing member, is so supported on a wheeled carriage as to be movable toward the workpiece. The weld backing is provided with follower elements which are always in contact with the underside of the workpiece and which turn following the movement of the workpiece to keep a predetermined gap between the underside of the workpiece and the weld backing so that desired bead thickness can be obtained. The wheeled carriage is moved synchronously with the movement of the welder to continuously perform full penetration welding.
