Non-contact, data-driven ultrasonic detection of seam quality
Innovative non-contact ultrasonic technology for detecting weld quality using piezocomposite, air-coupled transducers, eliminating the need for fluid couplants, and enabling rapid diagnostics. Suitable for applications in industries requiring precise seam quality evaluation.
Overview
This cutting-edge ultrasonic technology revolutionizes the detection of weld quality by using non-contact, air-coupled transducers. Unlike traditional methods that require fluid couplants, this approach offers a contact-free solution that avoids potential sample interactions and allows for rapid diagnostics. The technology is particularly beneficial for industries where precise seam quality evaluation is crucial, such as in automotive, aerospace, and manufacturing sectors.
Technical specifications
The platform leverages piezocomposite, air-coupled transducers to perform ultrasonic characterization of thin films. It maps density and elastic modulus variations without direct contact. The system features an open-source, user-friendly interface, allowing users to easily input ultrasound parameters and output 1D or 2D data. The signal processing capabilities have been demonstrated to detect variations in density and elastic modulus, making it adaptable for seam quality assessments.
Technology readiness level
This technology is currently at a Technology Readiness Level (TRL) of 4. It has been validated in a lab environment with plans for further adaptation and testing with industry partners. The next steps involve collaborating with partners to perform initial tests on a wide range of defect types, thicknesses, and temperature variations, ultimately preparing the platform for on-site usage.
