Nondestructive Testing (NDT) plays an important role in assuring that structural and mechanical components perform their function in a safe, reliable, and cost-effective manner.
NDT, Quality Control, and Quality Assurance are vital to the daily function of countless companies and civic-minded organizations. NDT Examinations are necessary to ensure safety and reliability for companies, personnel, products, and the public. Pipelines, bridges, motor vehicles, buildings, aircraft, water craft, power stations, trains, oil platforms, and refineries are all inspected using NDT testing methods.
After doing the course, you will be qualified to start a career in a vast array of fields such as:
- NDT Careers in Aerospace
- NDT Careers in Aviation
- NDT Careers in Auto and Boat Racing
- NDT Careers in Construction
- NDT Careers in Manufacturing
- NDT Careers in Oil and Gas Development
- NDT Careers in Amusements Parks
- NDT Careers in Railroad
- NDT Careers in Alternative Energy: Nuclear, Wind, Solar
Non Destructive Testing is very vast tropic to be discussed. It contains various inspection methods like:
- Ultrasonic Testing
- Radiography Testing
- Dye Penetratent Testing
- Magnetic Particle Testing
- Eddy current Testing
- Visual Testing
- Neutron Radiography
- Leak Testing. Etc
Levels of Qualification
Most certification programs have three levels of NDT qualification: Level I, Level II and Level III. Because the requirements for the levels are very similar, the descriptions provided here are from the 2006 edition of the ASNT Recommended Practice No. SNT-TC-1A.
- An NDT Level I individual should be qualified to properly perform specific calibrations, specific NDT and specific evaluations for acceptance or rejection determinations according to written instructions and to record results. The NDT Level I should receive the necessary instruction and supervision from a certified NDT Level II or III individual.
- An NDT Level II individual should be qualified to set up and calibrate equipment and to interpret and evaluate results with respect to applicable codes, standards and specifications. The NDT Level II should be thoroughly familiar with the scope and limitations of the methods for which he is qualified and should exercise assigned responsibility for on-the-job training and guidance of trainees and NDT Level I personnel. The NDT Level II should be able to organize and report the results of NDT tests.
- An NDT Level III individual should be capable of developing, qualifying and approving procedures, establishing and approving techniques, interpreting codes, standards, specifications and procedures, as well as designating the particular NDT methods, techniques and procedures to be used. The NDT Level III should be responsible for the NDT operations for which he is qualified and assigned and should be capable of interpreting and evaluating results in terms of existing codes, standards and specifications. The NDT Level III should have sufficient practical background in applicable materials, fabrication and product technology to establish techniques and to assist in establishing acceptance criteria when none are otherwise available. The NDT Level III should have general familiarity with other appropriate NDT methods, as demonstrated by an ASNT Level III Basic examination or other means. The NDT Level III, in the methods in which he is certified, should be capable of training and examining NDT Level I and II personnel for certification in those methods.
