Abstract: A plurality of values measured are relatively compared to determine an optical axis deviation direction in which an optical axis of a measurement beam deviates from a laser beam. Then, a first parallel plate and a second parallel plate are rotated to move an irradiation position of the measurement beam so that an optical axis of the measurement beam is substantially coaxial with an optical axis of the laser beam.

Abstract: A plurality of values measured are relatively compared to determine an optical axis deviation direction in which an optical axis of a measurement beam S deviates from a laser beam L. In performing laser welding in the optical axis deviation direction, an irradiation position of the measurement beam S is changed so that the irradiation position of the measurement beam S is moved to a rear side of the center of the optical axis of the laser beam L in the welding direction.
