摘要： An object is to provide a method and an apparatus for improving a residual stress in a tubular body, which are enabled to improve the residual stress reliably by clearly defining controlling rage for treatment conditions without depending on an installation state and configuration of the tubular body. When an outer-circumferential surface of a welded portion of a cylindrical tubular body (2) is irradiated with a laser beam that circles around an outer circumference of the tubular body (2), a heating width W in a circumferential direction heated by the laser-beam irradiation and a laser-beam moving speed V in the circumferential direction are set so that a stress in the circumferential direction in an inner surface of the tubular body (2) produced by the heating with the laser beam is at least larger than a yielding stress of a material that the tubular body (2) is made of.

Two pairs of mirrors (21-24) reflect inwards a skirting portion of the corresponding laser beam in the circumferential and axial direction of the tubular body (2) so as to irradiate the tubular body (2) with the laser beams.

摘要： An object is to provide a method and a system for improving a residual stress in a tube body, with which the residual stress can reliably be improved without heating excessively. From an irradiation start angle θs to a first predetermined angle θ1 on the tube body, an intensity of a laser beam is gradually increased from 0.5 to the steady output of 1.0 output ratio; from the first predetermined angle θ1 to a second predetermined angle θ2, the intensity of the laser beam is set at 1.0 output ratio; from the second predetermined angle θ2 to an irradiation end angle θe, the intensity of the laser beam is gradually decreased from the 1.0 output ratio to 0.5; and at the irradiation end angle θe, the intensity of the laser beam is set to 0. All these steps are performed at one turn of rotation in the method and the system for improving residual stress in the tube body.
