摘要： PROBLEM TO BE SOLVED: To provide an apparatus for improving the residual stress in piping with which the outer circumferential surface in a curving pipe part can be heated, too. SOLUTION: This apparatus is provided with a laser beam head part 6, a circumferential direction shifting means, a rotating means, a piping axial direction shifting means and a driving control instrument; and in this driving control instrument, when the laser beam 23A is irradiated to the outer circumferential surface at the small side of curvature radius in the curving pipe part 2B, the laser beam head part is rotated with the rotating means so as to separate from the outer circumferential surface in the curving pipe part. Further, the interference between the laser beam head part and the outer surface of the curving pipe part is prevented by shifting the laser beam head part to a straight pipe part directional side, and when the laser beam is irradiated onto the outer surface at the large side of the curvature radius in the curving pipe part, the laser beam head part is rotated with the rotating means so as to approach to the outer circumferential surface in the curving pipe part, and controlled so as to prevent that the laser beam head part is separated over from the outer circumferential surface of the curving pipe part, by shifting the laser beam head part to the curving pipe part directional side.

摘要： PROBLEM TO BE SOLVED: To relieve residual stress by efficiently heating a weld zone and heat-affected zone of T-piping by a laser beam. SOLUTION: The residual stress is relieved by heating the weld zone of the T-piping 50 by irradiating a laser beam emitted from a laser head 10. At that time, the position of the laser head 10 in the direction of θ is adjusted with a rotary traveling cart 3 traveling along ring rails 2. The position of the laser head 10 in the direction of Z is adjusted by sliding a vertical slide 4. The position of the laser head 10 in the direction of L is adjusted by sliding a radial slide 5. The α direction of the laser head 10 is adjusted by sliding a circular arc piece slide 7 along the circular arc piece. The β direction of the laser head 10 is adjusted by turning a laser head supporting piece 9. The position of the laser head 10 in the direction of γ is adjusted by oscillation.
