A method for forming a cylindrical body (40) utilizing a continuous weld is provided. The methods includes feeding a source material (16) including a first edge (36) and a second edge (38) from a coil (14) and offsetting at least one of the first edge (36) and the second edge (38). The method further includes spiraling the material (16) to form a cylinder (40), welding the first edge (36) and the second edge (38) together forming a continuous weld, and cutting the cylinder (40) to a selected length. To fabricate a jacket, a longitudinal cut is made in the cylindrical body (40), at least one cut out is cut, and the continuous weld is an outer fillet weld.
La présente invention concerne une méthode de fabrication d'un corps cylindrique (40) au moyen d'une soudure continue. La méthode comprend un matériau brut (16) comportant un premier rebord (36) et un second rebord (38), et de décentrage d'au moins un de ces deux rebords (36, 38). La méthode consiste également à courber le matériau (16) de façon à former un cylindre (40), à souder le premier rebord (36) au second rebord (38) en formant une soudure continue, et à couper le cylindre (40) à une longueur déterminée. Pour fabriquer une chemise, une coupure longitudinale est pratiquée dans le cylindre (40), au moins une découpe est exécutée et la soudure continue est une soudure d'angle extérieure.
