Abstract
PURPOSE: To prevent the stress concentration by the thickness deceases or lowering of fatigue strength at the circumferential welding of the same shape tube, etc., by expanding one of the inner diameter of opening part of the material to be welded so as to be the same with that of the other opening part and joining the groove.
CONSTITUTION: The enlarged part 7 is formed by expanding the tube having a small diameter and unfitness of inner diameter of the tube is eliminated after forming the groove parts 4, 4 of the tubes 1, 1 at the circumferential welding of the tubes 1, 1 having a different inner diameter. As a result, decrease of thickness of weld zone is not generated and plastic deformation capable of canceling the welding contraction deformation is generated by carrying out the circuit welding, is generated and the strain concentration is lightened.
