What are the NDT normal methods? 

According to NASA research and analysis, Many NDT methods can be divided into six major categories of about 70 kinds. But the most common-used practical applications reside in the types as follows.

Conventional non-destructive testing methods are:

Ultrasonic Testing (abbreviation UT);

Radiographic Testing (abbreviated RT);

Magnetic Particle Testing (abbreviation MT);

Penetrant Testing (abbreviation PT);

Eddy Current Testing (abbreviation ET);

Non-conventional non-destructive testing techniques are:

Acoustic Emission (AE);

Leak Testing (abbreviation LT);

Optical Holography;

Infrared Thermography;

Microwave Testing

Which are the applications of nondestructive testing?

Applied Area: 

    Non-destructive testing of raw materials; non-destructive testing during product manufacturing; non-destructive testing of products during usage (in service).

Object tested:

    - NDT of various materials (metals, non-metals, composites, etc.)

    - NDT of various workpieces (welded parts, forgings, castings, pipelines, etc.)

    - NDT of various construction (steel structure engineering, road construction, water conservancy and hydropower, bridge construction, airport facilities, nuclear power plants, etc.)

    - NDT of Safety and Security Engineering Project (airport security, container security, anti-terrorism riot, etc.).
