why ultrasonic hardness tester needed to test in these fields

Hardness testing for workpieces with high surface requirements for Ultra thin workpieces: Complex shapes or hard to reach areas

What kind of workpiece requires the use of an ultrasonic hardness tester ？

The following types of workpieces require the use of an ultrasonic hardness tester:

1. For workpieces with high surface requirements: Ultrasonic hardness testers will not leave obvious indentations on the surface of the workpiece, making them suitable for workpieces with high surface condition requirements. For example, in the heat treatment industry, if there are no obvious measurement marks on the surface of the workpiece, an ultrasonic hardness tester is a better choice.

2 Large and heavy workpieces: The portable design of the ultrasonic hardness tester allows for on-site measurement, making it particularly suitable for hardness testing of large and heavy workpieces.

3Ultra thin workpieces: For ultra-thin workpieces such as chrome plated, nitrided, carburized surfaces, thin plates, and thin-walled tubes, ultrasonic hardness testers will not penetrate the surface hardening layer and can accurately reflect the true surface hardness of the workpiece.

4 Workpieces that require rapid testing: The measurement time of ultrasonic hardness tester is only 1 second, which is tens of times faster than desktop hardness tester. It is suitable for occasions that require rapid testing, such as on-site full inspection of mass-produced products such as bearings.

5 Complex shapes or hard to reach areas: Ultrasonic hardness testers are suitable for measuring the hardness of various shaped workpieces, irregular parts, and even some extremely thin surface coatings, especially suitable for measuring workpieces with complex shapes or hard to reach areas.

The advantages of ultrasonic hardness tester include:

1 Non destructive testing: No indentation will be left on the surface of the workpiece, causing minimal damage to the workpiece.

2 Portable design: convenient to carry and suitable for on-site measurement.

3 Quick measurement: The measurement time only takes 1 second, which is tens of times faster than traditional hardness testers.

4 Wide applicability: Suitable for various complex shapes and hard to reach areas.

In summary, ultrasonic hardness testers are suitable for workpieces with high surface requirements, fast detection, portable measurement, and complex shapes or difficult to contact areas.
