Ultrasonic is an acoustic NDT technology where sound waves are being emitted and their reflections are being received and interpreted. The emitted sound waves, get partially or fully reflected on phases between materials of varying impedance. The reflected waves arrive at different times and with different energy levels. These differences enable a trained and experienced expert to draw conclusions about the inner of a structure and its condition. Ultrasonic gives the opportunity for providing preliminary inspection results and full analysis and detailed documentation.
Ultrasonic testing is complimentary with other NDT technologies and delivers answers where other technologies don’t. It can be used as Quality Assurance measure, long term monitoring or for condition surveys. Access from only one side of the structure is necessary.
