Welcome to [NDT Inspection Portal]’s acoustic emission (AE) group, a place for professionals to connect and discuss the latest techniques and technologies in AE.
Acoustic emission (AE) is a specialized field within non-destructive testing (NDT) and inspection that involves the detection and analysis of acoustic waves or vibrations emitted from materials or structures as a result of internal or external stimuli. It is an important aspect of ensuring the safety and reliability of components, structures, and materials in various industries, including manufacturing, construction, and engineering.
Acoustic emission (AE) involves the use of specialized sensors and equipment, such as piezoelectric transducers, to detect and analyze acoustic waves or vibrations emitted from materials or structures. It may involve the use of other NDT methods, such as ultrasonic testing and radiographic testing, to identify any potential issues or defects, such as cracks, porosity, or corrosion. AE is often used to monitor the integrity and performance of components, structures, and materials in real-time and to predict potential failures or issues. It is particularly useful in situations where it is not possible or safe to physically access the inspection site or to apply load or stress to the material or structure.
Our member group offers a platform for sharing knowledge and best practices on AE and its applications in various industries. Join our community of experts from around the world and be a part of the conversation on advancing the practice of AE and its applications in the field of NDT and inspection. Whether you are new to AE or an experienced professional, you’ll find valuable resources and a welcoming community in our group.

I would like to measure the acoustic speed in liquid titanium
: during laser gas alloying. The enclosed figure shows the intended
: arrangement. Can you give useful hints about suitable transducers
: and frequencies?
I suggest that you discuss your problem with C.K. Jen of the Industrial
Materials Institute of the National Research Council of Canada. He is
already doing ultrasonic measurements in other molten metals.
