Military equipment is often placed under heavy stress. An airplane's landing gear absorbs heavy runway impact. Submarine hulls withstand tremendous pressure in the ocean depths. In time, stress may cause structural weakening or damage. Non-destructive testers examine metal parts for stress damage. They use X-rays, ultrasonics, and other testing methods that do not damage (are non-destructive to) the parts tested.
What They Do
Non-destructive testers in the military perform some or all of the following duties:
- Inspect metal parts and joints for wear and damage
- Take X-rays of aircraft and ship parts
- Examine X-ray film to detect cracks and flaws in metal parts and welds
- Operate ultrasonic, atomic absorption, and other kinds of test equipment
- Conduct oil analysis and heat damage tests to detect engine wear
- Prepare inspection reports
Helpful Attributes
Helpful school subjects include math and metal shop. Helpful attributes include:
- Interest in machines and how they work
- Thoroughness and dependability
- Interest in operating test equipment
Training Provided
Job training consists of classroom instruction, including practice in testing metal parts. Course content typically includes:
- Methods for inspecting parts and welds
- Operation of X-ray and film processing equipment
- Operation of ultrasonic test equipment
- Preparation of test reports
Work Environment
Non-destructive testers work indoors in laboratories and aircraft hangars. They also work outdoors in shipyards and in the field.
Civilian Counterparts
Civilian non-destructive testers work for commercial testing laboratories, airlines, aircraft maintenance companies, and industrial plants. They perform duties similar to military non-destructive testers and may be called radiographers.
