Course Overview
This course addresses the required training by documents controlling the certification program, such as NAS-410, SNT-TC-1A, and NavSea Technical Publication T9074-AS-GIB-010/271. Course content conforms to the training subjects listed in ANSI/ASNT CP-105, Standard Topical Outlines for Qualification of Nondestructive Testing Personnel. When combined with laboratory-type hands-on training under the direction of a Level II or Level III, this course will meet the total hours of training required by the applicable certification document listed above.
Upon Completion, Learners Will Have Covered:
- Certification documents, terms of certification documents, and history of visual testing

- Lighting terms, photometry, physical effects; exam conditions
- Direct and indirect visual examination definition; contrast and definition; Proof of VT capability; ASME Section IX VT exams
- Tools of VT: Fillet weld gages, steel rule, Cambridge gage, Palmgren gauge, Hi-LO gauge, micrometers, loupes, light meter, rigid borescope, borescope magnification, fibrescope, viewing tips of borescopes, field of view of borescopes, automated systems, and manual systems
- Flaw recognition, scanning and probing angle, magnifiers, measurement techniques
- Basic weld joints, weld preparations, weld groove terminology, inspection points for welds, preheat and interpass heat temperatures, weld symbols, fillet weld terminology, weld discontinuities; 5 basic weld processes
- Discontinuity and defect terminology; three classifications of discontinuities; product forms such as ingot, casting, or forging; discontinuities in different product forms; stress risers
- Bolting discontinuities
- Pump examinations, pump discontinuities and operational problems; valve examinations; types of valves
- Component support functions and descriptions, restraints, and snubbers
