Abstract

PURPOSE:To form a circumferentially welded joint part having an excellent fatigue characteristic, by welding short pipes of a specific shape respectively to the end faces of a pair of steel pipes to be circumferentially welded to each other then welding the short pipes to each other. CONSTITUTION:Two short pipes 2 are inserted between a pair of steel pipes 1a, 1b to be circumferentially welded to each other. The wall thickness t1 in the parts of the pipes 2 facing the pipes 1a, 1b is made the same as the wall thickness t2 of the pipes 1a, 1b, and the wall thickness T1 in the other end part is made about 1.5-2 times of the thickness t2 of the pipes 1a, 1b; in addition, projection parts 12 are formed. The end parts of the pipes 1a, 1b and the pipes 2 are first subjected respectively to both-side welding to form circumferentially welded joint parts 3, whereafter the reinforcement of weld is chipped off. The pipes 2 are then butted to each other and are subjected to one-side welding from the outside to form circumferentially welded joint parts 4. The stress to be generated in the parts 4 is thus reduced and the fatigue strength is improved.
