While steel sheets are positioned and held by a holding mechanism, a first laser beam is applied to a heating region of the steel sheet to space the steel sheet from the other steel sheet by a predetermined distance. A second laser beam is applied to a welding region to weld the steel sheets. An amount of heat applied by the first laser beam, a moving speed of the first laser beam, and a focused spot diameter of the first laser beam are set to keep the sheet irradiated with the first laser beam in an unmelted state and plastically deform the sheet.

Laser beam welding method and apparatus

Vehicle body of a two-wheeled vehicle assembled by holding a plurality of center members on a center jig which may be movable between a setting station and a coupling station, setting side frame members on a pair of side frame jigs in a prostrate posture at a position laterally adjacent the coupling station with the side frame jigs being a jig frame formed of frame materials with spaces therebetween, welding the side frame members together by welding robots adjacent the coupling station, erecting the side jigs to position the welded side frames in position with respect to the center members on the center jig, and welding the side frames to the center members using the same welding robots extending through the spaces in the jig frame of the side frame jigs.
