Abstract

This study optimizes active thermal non-destructive testing (TNDT) models to determine sensitivity thresholds. We analyze the minimum size and maximum depth of air-type defects across four material groups. Optimization maximizes the signal-to-noise ratio, accounting for surface emissivity non-uniformity. Numerical uniform search defines optimal heating and cooling modes under a 100°C safety limit. The methodology significantly enhances TNDT sensitivity and industrial applicability.
