Shaped forgings are a common type of forging, and their irregular shape makes quality inspection relatively complex. The following are some commonly used methods for inspecting the quality of shaped forgings:
- Appearance quality inspection: mainly inspect the surface of shaped forgings to confirm whether there are cracks, inclusions, or other defects.
- Dimensional accuracy inspection: measure the size accuracy of shaped forgings, such as fluctuations, deviations, straightness, and other indicators to judge the size quality.
- Microstructure inspection: analyze the metallographic structure and perform hardness testing on the shaped forgings to judge whether the internal microstructure is normal and whether the material hardness meets the requirements.
- Magnetic particle flaw detection: use magnetic particle detection technology to detect defects in shaped forgings, such as foreign objects, pores, cracks, or inclusions.
- Ultrasonic testing: use ultrasonic waves to detect internal defects of shaped forgings and to guide subsequent processing technologies.
- Helium mass spectrometry leak detection: place the shaped forgings in a vacuum or low-pressure condition and use helium mass spectrometry to check for leaks.
The above are the common methods for inspecting the quality of shaped forgings. In actual production, it is necessary to select and apply them reasonably for specific products and requirements to ensure stable and reliable product quality and meet customer needs.
