Ultrasonic Depth Tester for Induction Hardened Layer TG-8000
Background:
Surface hardening treatment can improve the wear resistance and
fatigue strength of components subjected to dynamic stress. These
characteristics are mainly determined by the surface hardness,
hardened depth, and depth profile of residual stress. The depth of
the hardened layer is an important quality indicator in the surface
hardening treatment process. Currently, the quality of the
hardening process can only be ensured through random testing
methods. This method not only damages components, wastes time, but
also has a high cost.
Solution:
Our company uses a fast, non-destructive ultrasonic method to
measure the depth of hardened layers. This method can reduce the
inspection workload and cost, and ensure that the product is always
of high quality by adjusting the production process in time. The
instrument can optimize the manufacturing parameters, shorten the
idle time of the machine after replacing the inductive sensor,
realize the fast manufacturing control function and good quality
management.

Our equipment:
The device utilizes the following principle: the hardened layer has
almost no resistance to ultrasonic waves, while materials that have
not undergone hardening treatment will scatter a large amount of
ultrasonic waves. The detection system records the backscatter
signal and processes it with our electronic measuring elements.
Through comprehensive automatic data evaluation, the final hardened
depth of the material can be obtained.
