NDE Methods

• Flaw Detection and Evaluation
• Leak Detection
• Location Determination
• Dimensional Measurements
• Structure and Microstructure Characterization
• Estimation of Mechanical and Physical Properties
• Stress  and Dynamic Response Measurements
• Material Sorting and Chemical Composition .

Most Common NDT Methods

• Visual
• Liquid Penetrant
• Magnetic
• Ultrasonic
• Eddy Current
• X-ray

Visual Inspection

• Tools include fiberscopes, bores copes,magnifying 
  glasses and mirrors.
• Portable video inspection unit with zoom allows 
  inspection of large tanks and vessels, railroad tank 
   cars, sewer lines.
• Robotic crawlers permit observation in hazardous 
   or tight areas, such as air ducts, reactors, pipeline.

Magnetic Particle Inspection

The part is magnetized. Finely milled iron particles coated with a dye pigment are then applied to the specimen. These particles are attracted to magnetic flux leakage fields and will cluster to form an indication directly over the discontinuity.

Radiography Testing

The radiation used in radiography testing is a higher energy (shorter wavelength) version of the electromagnetic waves that we see as visible light. The radiation can come from an X-ray generator or a radioactive source.

Film Radiography

• The part is placed between the radiation source 
and a piece of film.
• The part will stop some of the radiation.
• Thicker and more distance area will stop more of 
   the radiation.
• The film darkness will vary with the amount of
   radiation reaching the film through the test object.
