Radiation detection

Radiation detection is most important to detect macroscopic geometric defects inside the test piece. Radiography refers to a non-destructive testing method in which a test piece is penetrated by X-ray or R-ray and a film is used as a device for record...

Ultrasonic testing technology level selection and quality as

The ultrasonic testing technology grade is divided into three detection levels: A, B, and C. Class A is the lowest level, low sensitivity; Class B is medium sensitivity; Class C is the highest level, high sensitivity...

Common methods and means for non-destructive testing of weld

Weld quality Ultrasonic testing is mainly used to detect internal defects in welded joints, such as pores, slag inclusions, unwelded heads, unfused, cracks and other welding defects. Ultrasonic waves have a higher detection rate than ray-like defects ...

Common welding defects

Welding defects are the phenomenon that the metal produced in the welded joint is discontinuous, not dense or poorly connected during the welding process....

Classification of non-destructive testing methods

Ultrasonic pulses are injected directly into the specimen, and ultrasonic echoes (transmission attenuation) can indicate the presence and location of defects, interfaces, and discontinuities....
