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.

摘要： A laser cutting apparatus (10) includes a laser processing head (15) that receives a laser beam emitted by a laser oscillator (12) and that uses a spherical lens for converging the laser beam so as to cause the intensity distribution of the laser beam to have a caldera-like shape, in which the intensity of the laser beam is higher in a peripheral area than in a central area, at the position of a workpiece (20). Moreover, the laser processing head (15) radiates the laser beam whose focal position is displaced from the position of the workpiece (20) to the workpiece (20). Therefore, the laser cutting apparatus (10) performs an inversion on the laser beam by using the spherical aberration of the spherical lens. Consequently, with a simple configuration, a laser beam whose inner area and outer area are inverted at the position of the workpiece (2) can be generated, and the processing direction for processing the workpiece (20) is not limited.
