Zusammenfassung:	PURPOSE:To improve the quality of a laser beam machine by preventing the focus displacement of CCD camera to photograph a work and precisely travel controlling a laser head. CONSTITUTION:A work 21 to be welded is traveled in the arrow mark direction A with butting a weld zone 22. A welding head 23 is placed so as to weld a weld zone 22. A position detecting sensor 26 is positioned in front of the welding head 23, the work 21 to be welded is irradiated with a belt-like beam by illumination parts 27, 28, photographing its optical cross sectional image by CCD camera 29. A data processing part 31 assumes the weld zone 22 as well as a vertical distance based on the image information, travel controlling the vertical position of CCD camera 29 by a distance correcting monitor 30 so as to set the position in the zone depth to be photographed, accordingly at all times the work to be welded 21 is precisely photographed, confirming the weld zone so as to execute welding.
