How to check the quality of cross shaft forging?

The quality of cross shaft forgings can be detected by the following methods:

Appearance inspection: Observe the surface quality of cross shaft forgings, including whether there are cracks, inclusions, heavy skin and other defects.

Size detection: Measuring the dimensions of the cross shaft forging, such as diameter, length, Angle, etc., to ensure that it meets the design requirements.

Mechanical properties testing: through tensile test, impact test, hardness test and other ways to detect the mechanical properties of cross shaft forgings, such as tensile strength, yield strength, impact toughness.

Metallographic detection: The microstructure of the cross shaft forgings, such as grain size and alloying element distribution, is observed through a metallographic microscope to evaluate its quality.

Non-destructive testing: Using ultrasonic testing, X-ray testing, magnetic particle testing and other ways of non-destructive testing of cross shaft forgings to find internal defects or surface cracks.

Functional testing: In some cases, it is necessary to carry out functional testing for cross shaft forgings, such as post-assembly running tests, braking performance tests, etc., to evaluate their performance in actual use.

To sum up, the quality of cross shaft forgings can be detected by a variety of methods, including appearance testing, size testing, mechanical properties testing, metallographic testing, non-destructive testing and functional testing. According to the actual situation, the appropriate method is selected for testing to ensure that the quality of the cross shaft forging meets the requirements.
