    摘要: Control is exercised such that an arc discharge from a GMA electrode is performed after or simultaneously with start of oscillation of laser light from a laser oscillator, and oscillation of the laser light from the laser oscillator is stopped after or simultaneously with termination of the arc discharge from the GMA electrode. A coaxial laser beam machining head is configured such that the GMA electrode is disposed in a space portion between a first divisional laser beam and a second divisional laser beam, which have been formed by division by first and second reflecting mirrors, coaxially with the laser beams. Alternatively, the coaxial laser beam machining head is configured such that the GMA electrode is disposed in a space portion, which has been formed in a body of laser light by withdrawing part of the laser light outwardly with the use of first and second reflecting mirrors, coaxially with the body of the laser light.

    摘要: A weld zone of T-piping and its neighborhood are efficiently laser-heated to remove residual stress. For this purpose, the weld zone of a T-piping (50) is irradiated and heated with a laser beam emitted from a laser head (10) to remove residual stress. At this time, a rotating travel cart (3) travels along a ring rail (2) to adjust the position of the laser head (10) in a θ-direction, a vertical slide (4) slides to adjust the position of the laser head (10) in a Z-direction, a radial slide (5) slides to adjust the position of the laser head (10) in an L-direction, an arcuate piece slide (7) slides along an arcuate piece to adjust the α-direction of the laser head (10), a laser head support portion (9) turns to adjust the β-direction of the laser head (10), and oscillation adjusts the position of the laser head (10) in a γ-direction.

    摘要: Aims are to provide a tubular-body residual-stress improving apparatus and an adjustment method thereof capable of adjusting irradiation position with favorable reproducibility, even when an optical fiber is eccentric. In the tubular-body residual-stress improving apparatus, an optical control unit (5) includes a rotational hold mechanism (9) for holding an optical fiber (6) in a manner that the optical fiber (6) is rotatable in a circumferential direction of the optical fiber (6), and, if a position of an intensity peak of the laser beam from the optical fiber (6) in an axial direction of the tubular body (2) is offset from the center of an irradiation profile, a position at which the optical fiber (6) is held in the circumferential direction is adjusted by the rotational hold mechanism (9) so as to eliminate the offset or to minimize an influence of the offset.
