Abstract

PURPOSE:To detect the seamed position after annealing highly accurately without errors, by projecting laser light having a specified wavelength at a specified incident angle, and discriminating a seamed part and a parent material part based on the anisotropy of an equal intensity curve of a reflected light intensity distribution. CONSTITUTION:Laser light is projected at an incident angle of more than 70 deg. and less than 90 deg., with the wavelength of the laser light being more than 0.2mum and less than 0.7mum. The laser light 12 from a helium neon laser light source 30 is made to scan in the lateral direction in the vicinity of a seamed part 10b by a beam scanner 32. Reflected patterns 22 and 22' are obtained on a screen 16. The images of the reflected patterns 22 and 22' are picked up by a CCD camera 34. An operating device 38 judges whether the images are longer in the direction of a longitudinal axis 20 or in the direction of a lateral axis 18 on the screen 16. A laser light projecting angle is detected by a mirror rotating position detector 33. When the reflected patterns 22 and 22' are longer in the direction of the lateral axis 18, the patterns are judged to be the seamed position, and the result is outputted.
