The flaw detection of agricultural machinery forgings is an important link to ensure product quality, the following are several common agricultural machinery forgings defect detection methods: Visual inspection: Use the naked eye to inspect the appearance of the forgings to observe whether there are obvious cracks, poor welding, deformation and other defects. This is the simplest and most intuitive method of defect detection, but some subtle defects may not be noticeable. Acoustic detection: ultrasonic detection equipment is used to detect forgings. The ultrasonic wave is received by the receiver after the transmission of the forging, and according to the received acoustic signal, it can be determined whether there are internal defects or cracks in the forging. This method is able to detect internal defects in forgings and is non-destructive. Magnetic powder detection: By applying a magnetic field after coating magnetic powder on the surface of the forging, cracks, pores and other defects on the surface and near the surface of the forging can be detected. Magnetic particle testing is suitable for the detection of forgings made of magnetic materials. Penetration detection: the forging is soaked in penetrant, and after it penetrates into the surface crack of the forging, it is wiped clean and the color developer is applied, and the surface crack is detected by dyeing. This method is suitable for surface defect detection of metal forgings. X-ray detection: The use of X-ray through the forging attenuation rate to detect the internal defects, foreign bodies, etc. X-ray detection can provide higher resolution and sensitivity, and the detection effect is better for some small defects. The above method is only a part of the flaw detection of agricultural machinery forgings, and more methods can be used to detect according to the specific situation to ensure the quality and reliability of agricultural machinery forgings. In practical application, it is suggested to choose the appropriate defect detection method according to different situations and requirements.
