A continuous welded joint running lengthwise along a cylindrical shell, critical for structural integrity and pressure containment in industrial vessels.
A longitudinal seam is a welded joint that extends parallel to the axis of a cylindrical shell, such as those used in pressure vessels, tanks, or piping. It is formed by joining the edges of rolled metal plates or sections along their length, typically using processes like submerged arc welding (SAW), gas metal arc welding (GMAW), or laser welding. This seam is subjected to circumferential stress (hoop stress) when the vessel is under internal pressure, making its quality and inspection crucial for safety and performance. It must meet strict standards for weld penetration, reinforcement, and absence of defects like cracks or porosity.

It resists hoop stress from internal pressure, and failure can lead to catastrophic rupture, making its design and inspection vital for safety.
Defects include lack of fusion, cracks, porosity, and undercut, which are detected via non-destructive testing like radiography or ultrasonic inspection.
