Ak. Gurvich et al., METHOD FOR MEASURING THE DISTANCE BETWEEN SOLITARY DEFECTS IN WELDED-JOINTS, Russian journal of nondestructive testing, 30(3), 1994, pp. 211-217
A method is proposed for measuring the distance between solitary defec
ts detected in butt-welded joints in ultrasonic or radiographic inspec
tion. A procedure and means of error reduction are recommended for dis
tance measurements performed by the proposed method.
