ITvis ACD - Automated Crack Detection System for Forged Components
The ITvis ACD system offers an advanced solution for automated crack detection, particularly designed for hardening cracks in forged components. Available in both semi-automated and fully automated configurations, the system allows for component feeding either via conveyors or manually, depending on the test stand setup. Leveraging machine learning algorithms, the system ensures automated, user-independent evaluation of test results. The process achieves remarkable speed, with inspections completed in less than 0.1 seconds, seamlessly integrating into existing production cycles. Its robustness against material and environmental variations surpasses traditional methods like eddy current inspection, ensuring a low pseudo-rejection rate. Induction thermography forms the foundation of ITvis ACD, offering non-destructive, non-contact evaluations ideal for both production and maintenance environments, often replacing conventional magnetic particle inspection for enhanced cost-efficiency.
ITvis ACD is the fully automatic crack detection system for detecting e.g. hardening cracks on forged components.
The test system is offered as a semi-automated or fully automated version. Depending on the test stand version, the parts can be fed either automatically via a conveyor or manually. The evaluation of the test results is always fully automated with machine learning algorithms, i.e. without the user’s intervention.
A single crack inspection takes less than 0.1 seconds and can be integrated into the process cycle in most applications. The robustness of the inspection method against irregularities in the material and contamination is very high compared to e.g. eddy current inspection, and the pseudo-rejection rate can be kept very low by using suitable image processing. Even more complex component geometries can usually be inspected.
In practice, an ITvis ACD thermographic inspection often replaces one or more magnetic particle inspection stations, and is thus extremely cost-efficient and benefits with a rapid payback.
Principle of the induction thermography test system
Induction thermography is a non-contact, non-destructive testing method that is very well suited for the non-contact and imaging characterisation of metal structures as well as metal-polymer composite materials. The method is particularly used when a non-contact measurement technique with short measurement times is required, e.g. for crack detection. Induction thermography is very robust and works even under difficult environmental conditions, and is suitable both in production and for maintenance. In contrast to dye penetrant testing or magnetic particle testing, the test specimens are tested completely without contact and without the use of chemical additives.
A test takes between 0.1 seconds and several seconds, depending on the material type and thickness. Ideally, the test takes place stationary, but can also be carried out in continuous motion if necessary.
