The quality control and testing technology of automobile forging mainly includes the following aspects: Component analysis: Through the analysis of the composition of the forging material, it can ensure that it meets the design requirements. The commonly used component analysis methods include spectral analysis, chemical analysis and X-ray fluorescence analysis. Tissue testing: The tissue properties of forgings have a direct impact on their strength and durability. The commonly used tissue detection methods include metallographic microscopy, scanning electron microscopy and microhardness testing. Size measurement: Automobile forgings need to meet certain dimensional accuracy requirements, so size measurement is an important means of detection. Common dimensional measurement methods include three coordinate measurement, laser measurement and optical projection measurement. Magnetic particle testing: Magnetic particle testing is a common non-destructive testing method, suitable for the detection of surface and near-surface defects. By applying magnetic powder and applying magnetic field, defects such as cracks, inclusions and pores in forgings can be detected. Ultrasonic detection: Ultrasonic detection can be used to detect defects inside forgings, such as cracks and inclusions. By sending ultrasonic pulses and receiving the reflected ultrasonic signal through the receiving probe, defects in the material can be analyzed. Hardness testing: Hardness testing can be used to assess the hardness and strength of forgings. Commonly used hardness test methods include Rockwell hardness test and Vickers hardness test. Dynamic mechanical properties testing: Dynamic mechanical properties testing can evaluate the strength, toughness and fatigue life of the forgings. The commonly used dynamic mechanical properties test methods include impact test and fatigue test. The above are some common means and methods of automobile forging quality control and testing technology, which can ensure that the quality of automobile forging meets the design requirements and ensure its safety and reliability.
