Beschreibung
Zusammenfassung:	The present invention relates to a workpiece location photoelectric measurement control system of sheat laser cutting-welding machine. It comprises computer system, servo-motor, CCD camera and image card. The CCD camera and image card can be used for respectively shooting position image signals of standard workpiece and working to be welded, and transferring them into the computer system. The comparison of the position image signal of workpiece to be welded with position image signal of standard workpiece can produce an error value, according to said error value the computer system can control the servo-motor to move the workpiece to be welded to preset position.
