Non-destructive testing refers to the method of inspecting and testing the specimen without damaging the specimen, also called non-destructive testing. With the development of modern science and technology, laser, infrared, microwave, liquid crystal and other technologies have been used in the field of non-destructive testing, and traditional conventional non-destructive testing technology has greatly enriched the application methods due to the development of modern technology.
Non-destructive testing is an indispensable and effective tool for industrial development. To a certain extent, it reflects the level of industrial development of a country, and its importance has been recognized.
Non-destructive testing is NonDestructive Testing, abbreviated as NDT (or NDE, non-destructive examination), also called non-destructive testing. Technology combined with instruments to detect defects, chemical and physical parameters of materials, parts and equipment.
Features of NDT:
Does not destroy the inspected object.
100% inspection is possible.
Defects are found and evaluated to assess the quality of the object being inspected.
It can make judgments on the causes of defects and development laws, so as to promote the relevant departments to improve the production process and product quality.
Regular inspection of key parts during operation, and even long-term monitoring to ensure safe operation and prevent accidents.
Nondestructive testing methods
Conventional nondestructive testing methods:
Ultrasonic Testing (UT)
Radiographic Inspection (RT)
Magnetic Particle Testing (MT)
Penetration Testing (PT)
Eddy Current Testing (ET)
Conventional nondestructive testing methods refer to the widely used and mature nondestructive testing methods.
In addition, other non-destructive testing methods: Acoustic Emission Testing (AT), Thermal Imaging/Infrared (TIR), Leak Testing (LT), AC Field Measurement Technology (ACFMT), Magnetic Leakage Testing (MFL), Far Field Testing method (RFT) etc.
