Fast Charging Flaw Detector Ultrasonic With Lithium Ion Battery

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.

Cong

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.
