Abstract
In the production of metal tubes welded longitudinally, the invention makes it possible to fully exploit the possibilities offered by the technique of moving the welding defects normally found in correspondence with the ends onto plates appropriately inserted onto the ends of the tubes themselves. The above is obtained by using plates of the same thickness as the tube and providing it with the same caulking, independently from the fact that they may not be mounted perfectly aligned with the tube walls. <IMAGE>
