Abstract
A method for manufacturing a welded cylinder is provided wherein a seal (such as an O-ring seal or a cured polymeric sealant) is disposed between the tube of a cylinder and its welded end plug. The seal is spaced away from the circumferential weld that joins the end plug to the cylinder to reduce the hoop stress in the tube adjacent the weld, thereby reducing the tensile stress at the weld joint.
