The estimation of the size of the artificial defects by the ultrasonic B-scope angle beam testing is investigated experimentally and the results obtained are summarized as follows. (1) The distributions and length of the weld defects in a joint can be recorded with single photograph by the ultrasonic B-scope angle beam testing. (2) The length of the planar defects and two dimensional defects can be estimated by the ultrasonic B-scope angle beam testing almost as well as the X-ray testing so far as adjusting previously the effects of the angle of beam spread. (3) The method to evaluate the shape of weld defects by the ultrasonic B-scope angle beam testing is examined and succeeded to some extent. (4) The height of weld defects can be estimated by the ultrasonic B-scope angle beam testing with some precision so far as adjusting previously the effects of the angle of beam spread (see, Fig.13).
