Visual Testing - Level I & II (Combined)
This Visual Testing 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.
The training is divided into fifteen (15) chapters. They include:
1. Certification documents; terms of certification documents; history of visual testing
2. Defining Visual Testing; electromagnetic spectrum; requirements for visual testing; eyesight and features of the eye; visual acuity and color discrimination deficiencies; measurement of visual acuity
3. Lighting terms; photometry; physical affects; exam conditions
4. Direct and indirect visual examination definition; contrast and definition; Proof of VT capability; ASME Section IX VT exams
5. 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; manual systems
6. Flaw recognition; scanning and probing angle; magnifiers; measurement techniques
7. Basic weld joints; weld preparations; weld grove terminology; Inspection points for welds; preheat and interpass heat temperatures; weld symbols; fillet weld terminology; weld discontinuities; 5 basic weld processes
8. Discontinuity and defect terminology; three classifications of discontinuities; product forms such as ingot, casting or forging; discontinuities in different product forms; stress risers
9. Bolting discontinuities
10. Pump examinations; pump discontinuities and operational problems; valve examinations; types of valves
11. Component support functions and descriptions; restraints; snubbers
12. Ceramic discontinuities; composite discontinuities; electronic components examinations
13. Material failure processes such as creep, stress corrosion cracking, thermal fatigue and mechanical failure
14. Machine vision
15. Codes, specifications, and standards; checklist requirements; procedure requirements
This training will meet most certification documents for visual testing such as SNT-TC-1A, and encompasses the subject matter listed in ANSI/ASNT CP 105 outline for visual testing certification. Please verify that the employer’s written practice (document for certification of NDT personnel) allows for online training. Upon satisfactory completion of all training material and exams, a training certificate will be issued. Please secure this document in a safe location, as it may be needed multiple times throughout your career.
The instructor for this course is Gary D. Larson, who has 45-years’ experience performing NDT, including 35 years as a NDE Level III. He holds an ASNT Level III certificate in UT, RT, PT, MT and VT.
Note: Recommend reading assignments are provided for each lesson, which are listed at the beginning of the course. Completion of the readings and self-study is strongly encouraged and will add to the overall training benefit and time to be credited. It will also better prepare the student for the practical/hands-on session. It is recommended that the student keep a log of self-study time. It is also recommended that the applicable Level III be involved and confirm that the reading and self-study assignments have been completed. This should become a part of the student’s training records.
