Abstract

A thermal technique and system for measuring the depth of a crack in metal is described. The transient heat signature of a moving infrared laser source is analyzed using three intensity-based algorithms and the limitations of this approach are examined. Experimental results demonstrate capability to measure EDM-notches 0.06 inches deep and shallower, and the variability of the system agrees with the theoretical. The advantages and disadvantages of this technique over other non-destructive testing (NDT) methods are also outlined.
