The non-destructive testing technology of agricultural machinery forgings is mainly used to evaluate the quality of agricultural machinery forgings and detect defects. Non-destructive testing is a non-destructive material testing method, through the analysis of the material, structure and performance of agricultural machinery forgings to determine whether there are defects, damage or other quality problems. The commonly used non-destructive testing technology for agricultural machinery forgings includes the following: Ultrasonic testing (UT) : Using the principle of ultrasonic propagation in the material, by sending and receiving ultrasonic signals to detect internal defects in the material, such as cracks, pores and so on. This technique can provide detailed information about the location, size, and shape of the defect. Magnetic particle detection (MT) : Using the change of magnetic field on the surface of the material to detect surface or near-surface defects inside the material, such as cracks, inclusions, etc. By spreading magnetic powder on the surface of the material, the accumulation of magnetic powder at the defect can be observed, so as to judge the existence of the defect. Penetration testing (PT) : The permeable liquid is coated on the surface of the material, and after a certain period of time, the color developer is used to observe whether the liquid is immersed in the inside of the material to determine whether there are surface defects or pores. X-ray inspection (RT) : Using X-ray, gamma or neutron rays to penetrate the properties of the material, by detecting the intensity and distribution of the transmitted rays to assess the quality of the material and detect internal defects, such as cracks, inclusions, etc. This method can provide better comprehensiveness and depth. The above is the common non-destructive testing technology of agricultural machinery forgings. According to the specific needs and actual situation, the appropriate technology can be selected for application to ensure the quality and safety performance of agricultural machinery forgings.
