摘要： A butt welded tubular structure composed of tubular members of austenite stainless steel including a restraining member providing a cover to the entire outer circumferential surfaces of a welded joint and heat affected zones of the tubular members, the restraining member being formed of a metal or alloy of lower stress corrosion cracking sensitivity than the material of the tubular members and joined at the entire surfaces of opposite end portions thereof to the tubular members by welding, although the restraining member is not joined to the tubular members at portions of the restraining member corresponding to the welded joint and heat affected zones of the tubular members. The butt welded tubular structure is produced by joining tubular members of austenite stainless steel by butt welding, covering the entire outer circumferential surfaces of the welded joint and heat affected zones of the tubular members with a restraining member formed of a metal or alloy of lower stress corrosion cracking sensitivity than the material of the tubular members, and joining by welding the entire surfaces of opposite end portions of the restraining member to the tubular members while avoiding the joining of the restraining member to the welded joint and heat affected zones of the tubular members at portions of the restraining member corresponding to the welded joint and heat affected zones.
