<p>Method and apparatus for automatically applying paint marks to a pipe at the longitudinal and circumferential locations where anomalies are detected by nondestructive inspection apparatus. The inspection apparatus consists of two inspection units spaced apart along the path of the object. The first unit senses for circumferential flaws. The second unit senses for longitudinal flaws. The sensor outputs are each fed to a shift register which transmits the flaw information to a marker downstream.</p> |
