Electromagnetic Acoustic Transducer Ultrasonic Testing
Ultrasonic testing with EMAT technology generates sound waves through electromagnetic alternating fields and detects them to identify flat spots or cracks. It is a non-contact method.
Physicochemical Mechanism of Action
The EMW technology uses electromagnetic alternating fields to generate sound waves in the material and interpret them again. This enables precise detection of flat spots or cracks.
Metallurgical Relevance & Risks in Welding
This testing method is particularly useful for checking weld quality and integrity. Incorrect settings can lead to inaccurate results, causing misunderstandings in material testing.
Workshop Practice & Instructions
Use the technique with correct settings and continuous calibration. The sound wave frequency should be between 1 MHz and 5 MHz, depending on the material and the test task. Ensure a clean surface of the material to be tested.
