The non-destructive testing methods used in the quality inspection of forgings generally include: magnetic particle testing, penetrant testing, eddy current testing, ultrasonic testing, etc.
Magnetic particle inspection is widely used to inspect surface or near-surface defects of ferromagnetic metal or alloy forgings, such as cracks, hair lines, white spots, non-metallic inclusions, delaminations, folds, carbides or ferrite Wait.
This method is only applicable to the inspection of forgings made of ferromagnetic materials. This method is not suitable for forgings made of austenitic steel. In addition to inspecting magnetic material forgings, the penetrant inspection method can also inspect the surface defects of non-ferromagnetic material forgings, such as cracks, looseness, folding, etc. It is generally only used to inspect the surface defects of non-ferromagnetic material forgings and cannot detect hidden surface defects. The following defects. The eddy current inspection method is used to inspect surface or near-surface defects of conductive materials. Ultrasonic inspection is used to inspect internal defects of forgings such as shrinkage cavities, white spots, core cracks, slag inclusions, etc. Although this method is convenient, fast and economical to operate, it is difficult to accurately determine the nature of the defects.
With the development of non-destructive testing technology, new non-destructive testing methods such as vibroacoustic method, acoustic emission method, laser holography method, etc. have emerged. The emergence of these new methods and their application in forging inspection , will definitely greatly improve the level of forging quality inspection.
It is worth mentioning that the accuracy of forging quality inspection results depends on correct test methods and testing technologies, but it also depends on correct analysis and judgment. Only correct test methods without accurate analysis and judgment will not lead to appropriate conclusions. Therefore, the analysis of forging quality is actually the comprehensive application of various testing methods and the comprehensive analysis of each test result. Problems arising from large and complex forgings cannot simply rely on a certain method. From this point of view, it can be said that various Test methods are complementary to each other in the analysis process. Only by organic cooperation of various test methods and comprehensive analysis of their respective test results can correct conclusions be drawn. At the same time, for the purpose of forging quality analysis, in addition to correct inspections, necessary process tests should also be conducted to find out the real causes of quality problems and propose perfect improvement measures and prevention countermeasures.
Of course, which testing methods should be used in actual work and which testing methods should be used should be based on the type of forgings and the specified testing items. When selecting test methods and testing means, we must take into account not only advancement, but also practicality and economy. We cannot simply pursue advancement. If you can solve a problem with one means, don't use two or more. The selection of testing methods should be based on accurately determining the nature of the defect and accurately identifying the cause of the defect. Sometimes the selection of testing methods that are too advanced will lead to unnecessary consequences and undue losses.
Forgings need to be consistent from piece to piece, without any porosity, excess space, inclusions or other imperfections. This method produces components with a high strength to weight ratio. These elements are commonly used in aircraft structures. The advantages of forgings are extendable length, retractable cross-section, retractable length, extendable cross-section, changeable length, and changeable cross-section. The types of forgings include: free forging/hand forging, hot die forging/precision forging, upset forging, roll forging and die forging.
