General Process of Forging Quality Analysis
Forging is a forming process in which a force is applied to a metal between two dies shaped as desired to produce desired shapes, such as shafts, discs, rods, and rods. When producing forgings from metal, it is important to monitor its quality during the forging process. In order to ensure the quality of forgings, a systematic analysis should be carried out to determine the causes of any quality defects. This article will introduce the general process of forging quality analysis.
The first step in a forging quality analysis is to select a suitable test specimen. The selected specimen should represent the desired shape and size of the forging. In addition, the sample should be taken from its original forging position. By taking samples at different points in the forging process, the influence of various process conditions on the specimen can be evaluated.
The next step is to inspect and evaluate the test specimen. This is usually carried out using non-destructive testing methods such as visual inspections, X-ray inspections, or ultrasonic inspections. These inspections are used to identify any potential flaws or defects in the sample, such as cracks, porosity, and inclusions. In addition, the surface condition of the sample should also be evaluated.
Once the defects in the test specimen have been identified, a detailed analysis of the sample should be conducted to determine the root cause of the quality defect. This may involve the use of computer-aided engineering (CAE) analysis, which can simulate the forging process and determine the effect of different process conditions on the forging. In addition, metallographic analysis can be used to examine the microstructure of the forging and identify any structural flaws.
Once the root cause of the quality defect has been identified, corrective measures can then be implemented to prevent the occurrence of similar quality issues in the future. This may involve making adjustments to the forging process parameters, such as forging temperatures, or it may involve changing the composition of the forging material. By implementing these corrective actions, it is possible to improve the quality of the forgings and ensure that they meet the required standards.
In conclusion, a quality analysis of forged components is essential in order to ensure that they meet the required standards and specifications. The general process of forging quality analysis involves selecting a suitable test specimen, performing non-destructive testing, analyzing the specimen to identify potential defects, and implementing corrective measures. By following this general process, it is possible to improve the quality of the forgings and ensure that they are produced according to specifications.
