摘要： Avoidance of the corrosion initiation sites consisting of Mn particles deposited on the TiG welded inner tube surface is achieved through suppression of emission of manganese fumes by addition of a protective non corrosive metallic layer. The latter melts during the welding and arises in a non-corrosive internal metallic coating of the welded zone.
