NDT - Penetration Testing Level2

This course covers the concepts of Penetrant (also called Liquid or Dye Penetrant) Testing, an NDT method used to detect cracks and cavities open on the surface of nonporous metallic materials. Liquid Penetrant Testing is one of the simplest and most popular NDT methods for inspection.

In this course, we will cover the required concepts around penetrant testing training necessary for completion of the PT certification program. This is essential for ensuring compliance as per NAS-410, SNT-TC-1A and NavSea Technical Publication T9074-AS-GIB-010/271.

The training is divided into eight (8) chapters.

1. Penetrant history, capillary action and wetting, cohesion and adhesion, and the methods of liquid penetrant testing

2. Surface preparation; pre-cleaning; and the various liquid penetrant systems

3. Safety; LOX materials; penetrant application techniques; penetrant dwell times; temperature limits; excess penetrant removal techniques and over cleaning precautions; advantages and disadvantages of each removal technique; developer types and application

4. Interpretation and evaluation; false, non-relevant and relevant indications

5. Quality Control test; Tam panel; Comparator Block

6. Terminology; product discontinuities by product form such as casting, forgings etc.; discussion of methods to make the different product forms and welding

7. System classifications by Type, Method, Developer forms; penetrant terms such as wetting ability defined; procedure requirements

8. Typical qualification and certification documents; SNT-TC-1A overview

This course content conforms to the training subjects listed in ANSI/ASNT CP-105, Standard Topical Outlines for Qualification of Nondestructive Testing Personnel. This training will meet most certification document for liquid penetrant testing such as SNT-TC-1A. It encompasses the subject matter listed in the ANSI/ASNT CP 105 outline for liquid penetrant certification. Upon satisfactory completion of all training material and exams, a training certificate will be issued.
