Forging flaw detection is a process of inspecting internal and surface defects in forged products. The purpose of flaw detection is to ensure the integrity and reliability of the forged products. During the forging process, various defects such as cracks, folds, pores, and inclusions may occur due to the deformation and flow of the material. To guarantee product quality and safety, these defects must be detected and evaluated.
Common methods of forging flaw detection include magnetic particle inspection, ultrasonic testing, and radiographic inspection. Magnetic particle inspection is primarily used to detect surface and near-surface defects in ferromagnetic materials; ultrasonic testing utilizes high-frequency sound waves propagating through the material to detect internal defects; radiographic inspection employs the penetrating power of X-rays or gamma rays to detect internal defects in the material.
Each of these flaw detection methods has its advantages and disadvantages, and the choice of method depends on factors such as the material, shape, size of the product, and the required precision of inspection. Through forging flaw detection, defects in forged products can be effectively identified, allowing timely corrective measures such as repair or scrapping to ensure product quality and safety.
