Abstract: PURPOSE:To make it possible to inspect a flaw generated by welding with high accuracy, by calculating the position of a probe with due regard to the radius of curvature of a specimen. CONSTITUTION:In the manual scanning of a probe 6, when a probe holding part 17 is moved, a ball screw 13 is rotated. The number of rotations are detected by an encoder 15 and the position (l) of the probe 6 on a flaw detection arm 5 is calculated. A piping diameter D, the radius of curvature R of an elbow and the height AA'=h of the probe holding part are imparted from the planning value or made-up dimension of an ultrasonic flaw detection apparatus and the distance S between the connection part B of a moving body 4 and the flaw detection arm 5 and a welded line 3 and the height H of a point B from a straight pipe 1 are calculated by measurement after the ultrasonic flaw detection apparatus was mounted to the straight pipe 1. By this method, the positions A0', A' of the probe 6 based on the welded line 3 are calculated.

Filed: 1993-03-01
Abstract: PURPOSE:To obtain a substrate holder for holding a small disc type substrate positively at the outer end part thereof by pressing a rotating substrate using centrifugal force acting on an auxiliary substrate holding part thereby preventing the rotating substrate from falling off. CONSTITUTION:When a substrate mounting/demounting member 40 is pushed while resisting against the pressing force of a spring 30, a T-shaped part 20 rotates in the direction 45 around a shaft 22. When a substrate 4 is set at a predetermined position under that state and the member 40 is released, the substrate 4 is mounted on a substrate holder by means of substrate holding parts 12a-12c. When the substrate holder rotates, centrifugal force acts on an auxiliary substrate pressing part 18a in the direction 48 and tries to rotate the T-shaped part 20 in the direction 36 through a fulcrum 22 thus pressing the holding parts 12a-12c against the central part of the substrate 4.
