Paper Abstract

Thermographic nondestructive testing techniques have been receiving increasing attentions as one of the effective NDT techniques, because of its non-contact, remote sensing, time-saving, and cost-saving vision techniques. However, the defect detecting ability of this technique basically depends on environmental condition such as surrounding temperature, initial temperature of inspection target, emissivity and so on. Most of thermographic NDT engineers have been concerned about this problem, also. This paper proposes two reference specimens, aluminum alloy and stainless steel for evaluating detecting ability of photothermal thermography nondestructive inspection system. This paper will improve on the reliability of thermographic NDT technique.
