Electromagnetic Acoustic Transducer Testing
Electromagnetic ultrasonic testing generates sound waves through electromagnetic interaction and detects them directly in the material. This enables testing at high temperatures without coupling media.
Physical-Chemical Mechanism of Action
Electromagnetic acoustic testing (EMUS) uses electromagnetic fields to generate and detect sound waves in the material. This is done without coupling media such as water or oil.
Metallurgical Relevance & Risks in Welding
EMUS is particularly useful for inspecting weld quality at high temperatures where conventional ultrasonic methods are not applicable. It can detect cracks and defects in the material structure without touching or cooling the material. Incorrect use could lead to errors, as the technique requires specific conditions.
Workshop Practice & Instructions
For EMUS application, special equipment and knowledge are required. The temperature of the material should be in the optimal range to ensure effective wave generation. It is important to calibrate the device correctly and set the inspection parameters to obtain reliable results.
