What is NDT and its application?

Contact Us. Non-destructive testing (NDT) is a testing and analysis technique used by industry to evaluate the properties of a material, component, structure or system for characteristic differences or welding defects and discontinuities without causing damage to the original part.

When was NDT first used?

However, the first recorded use of NDT came in 1868, when Englishman S.H. Saxby chronicled in the journal, “Engineering,” a method of detecting longitudinal cracks in gun barrels using the magnetized needle of a compass.

How do I apply for an NDT test?

Applications for ASNT NDT Level III certification must be completed online through www.ASNT.org for consideration. All documentation can be attached and submitted digitally in the online application.

Who is the founder of NDT?

Early technical X-ray applications in Germany were realized by Richard Seifert around 1930. He improved medical equipment, cooperated with welding-institutes and built up the small company founded by his father to a world-wide respected name: Richard Seifert Hamburg 13.

Who created NDT?

Originated by Karel and Berta Bobath in the 1960s, NDT has since evolved to incorporate emerging theories of sensorimotor learning, and uses guided or facilitated movements as a treatment strategy to ensure correlation with input from tactile, vestibular, and somatosensory receptors within the body.

What is NDT process?

Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used.

What are NDT principles?

NDT is: • An advanced ‘hands-on’ therapeutic approach that helps guide the individual to more efficient functional abilities. It utilizes principles of motor development, motor control, motor learning, and other supporting scientific principles to improve basic body functions.

Why is NDT important?

As a quality control and quality assurance management tool, NDT plays a vital role in industries such as aerospace, pipelines, bridges, refineries and oil platforms as well as power stations as it can help prevent failures that could have an adverse impact on safety, reliability, and the environment.

What is NDT type?

Many different NDT methods are available in the industry, each of them having their own advantages and limitations, but six of them are most frequently used: ultrasonic testing (UT), radiographic testing (RT), electromagnetic testing (ET), magnetic particle testing (MT), liquid penetrant testing (PT) and visual testing …
