PURPOSE:To perform detection of a weld line and the welding work automatically in accordance with measured data, by providing a light projector and a photodetector at two points a part in a certain distance from each other on the axis of a measuring head for robot so that they face each other. CONSTITUTION:An oscillator I has about 100MHz oscillation frequency, and its output omegaL is amplified by an amplifier AMP1, and the light modulated by a frequency omegaL/2pi is radiated from a light projector L, and the reflected light (where a signal light and a noise light are superposed) from the surface of an object G to be measured is received by a photodetector R. In this case, the light projector L and the photodetector R are provided at two points apart in a certain distance from each other on the axis of the measuring head for robot so that they face each other. By this constitution, the detection of the weld line and the welding work are performed automatically in accordance with measured data. |
