For decades, Ultrasonic Testing (UT) has been the gold standard for verifying asset integrity, yet it remains plagued by operational “friction”. Traditional piezoelectric transducers require a liquid coupling medium, such as water or gel o transmit sound waves into a material. This necessitates extensive surface preparation, including the removal of coatings, rust, and dirt, followed […]
