Defects of large gear castings such as air holes, slag inclusions are sometimes inside the large gear products. These air holes and slag inclusions are not easy to find. At this time, non-destructive testing is required. Nondestructive testing can find these defects, and non-destructive testing of large gear castings. It is especially important.
Non-destructive testing is the application of certain physical phenomena to inspect the surface and internal defects of large gear castings without damaging the large gear workpiece. For large gear blanks, the finished large gears are flaw-detected, and defects can be detected early to determine whether these large gear parts are qualified. Sometimes the flaw detection can also be used to select the processing parts, which can save labor, shorten the production cycle and improve the product qualification rate; For flaw detection of finished large gears, unqualified products can be found to ensure the quality and safe use of large gear products; for large-scale gear processing equipment to conduct regular flaw detection, equipment accidents can be prevented in time; when we develop new products and new processes, we will detect them. We can find problems, explore the law, and take timely measures to promote the R&D work to achieve the expected results.
