Gary Larson has over 40 years of experience performing NDT on pipe welds, cast steel valves, ductile iron castings, and various aerospace industry applications. He is an ASNT Level III certificate holder in Radiographic Testing, Ultrasonic Testing, Penetrant Testing, Magnetic Particle Testing, and Visual Testing. He also holds an ACCP certification in Magnetic Particle Testing and Penetrant Testing.

Mr. Larson has performed X-ray and Gamma-ray radiography using film, amorphous selenium plates, and phosphor imaging plates. Mr. Larson has Ultrasonic Testing experience on various metals, steel welds, and composite materials. In addition, he has extensive experienced in Penetrant Testing using visible and fluorescent penetrant techniques. His Magnetic Particle Testing experience includes techniques using yokes, prods and wet horizontal equipment. He has extensive experience in Visual Testing. 

He worked for 23 years directly in the nuclear industry in piping, welding and valves.  He has worked with Sikorsky Aircraft performing UT, RT, MT and PT at the Bridgeport, Shelton and Stratford plants.  He has performed training in UT, MT, PT and RT for various plants with Sikorsky Aircraft and Pratt and Whitney Aircraft plants.  He is currently a consultant level III for a customer supplying Boeing Parts, and a customer supplying Military parts requiring NAS-410 certification.

ASNT Level III certificates held during the production of online NDT courses taught by Mr. Larson include Magnetic Particle Testing, Penetrant Testing, Radiographic Testing, Ultrasonic Testing and Visual Testing. 

Previous certifications included AWS Certified Welding Inspector, and Electric Power Research Institute Flaw Sizing. Gary is currently a member of ASNT and an active member of the E-07 Committee of ASTM.

Course Description: 

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.

The training is divided into fifteen chapters. 

  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.

NOTE: Please note the contact hours being awarded for this course.  To meet the training requirements in SNT-TC-1A, CP-189, and NAS-410, the student must complete the eLearning course and the necessary practical lab/hands-on sessions. These lab sessions must be overseen and documented by a Level III to ensure the required training hours are fulfilled.
