Tap Testing vs. Thermography

The authors of the article ‘Tap Testing vs Thermography’ which appeared on the January 2017 issue are responding to its critique by J.B.
Firstly, we thank J.B. for providing at least two very valuable references to quantitative assessments of NDT techniques applied to detecting flaws in aircraft composite laminate structures. (DOT/FAA/TC-15/4 & DOT/FAA/TC-15/6). The authors are also aware of Scandia Labs, in fact one of the authors visited and spent the better part of a day in the Lab at the Albuquerque airfield about 10 years ago. However, we believe J.B. misinterpreted the intention and conclusion of the article which was not to provide information or starting a study of POD (Probability of defect detection), but rather the comparison of two NDT techniques in dealing with monolithic/uniform metallic (hence dense/stiff (Normally, associated with the material’s Young’s modulus) and high thermal diffusivity (Normally strongly associated with the material’s thermal conductivity) vs. nonmetallic low thermal diffusivity materials. Both NDT techniques easily can be used as initial approaches in detecting discontinuities in the body beneath the surface of the component/structure. The article proves that the material’s properties do influence the outcome of the tests and hence it was concluded that the efficacy of a NDT technique to proceed with say a POD study, is substantially dependent on matching the technique with the material’s properties of the test pieces.

Research and Applications Development For NDT

The Research and Applications Development (RAD) group is a newly formed team within Acuren dedicat
ed to tackling challenging inspection problems. Our focus is the development of novel, field deployable, advanced inspection techniques for use in cases where standard NDT methods are ineffective. We don't wait for new innovations, we engineer them. From concept to commissioning.
