Abstract: 〗In the case where the diameter of the container is small, the welding operation space is limited, and the welder cannot perform rootcleaning welding from the inside of the shell, the welding manufacturing of high-pressure spherical container with small diameter and thick wall is realized by formulating a reasonable manufacturing process plan and welding method. This ensures the safe and reliable welding quality and provides reference for the welding manufacturing of high pressure spherical containers with small diameter thick wall.

Key words: small diameter, thick wall, spherical tank, welding, manufacturing
