High-accuracy workpiece position detection sensor using laser.

•     Realizes higher speed and higher accuracy than those of the touch sensor.
•     Allows high accuracy detection for a wide spectrum of applications from thin plate to medium thickness plate.
•     Allows recognition of various welding joints by easy operation.
•     Allows visual check of the recognition result using a teach pendant.
•     Enables automatic change of the welding condition based on the recognition result.
•     Can be used for applications other than welding.
