In the United States of America many welded components on existing bridges are prone to fatigue failure. The US Federal Highway Administration (FHWA) estimates that $76 billion is necessary to repair deficient bridges throughout the country.

Research conducted by Purdue University in 2018 has shown that Ultrasonic impact treatment is a highly effective technique for increasing the fatigue life of welded girders.

The study was recently extended to prove that equipment manufactured by Empowering Technologies is accepted as a reliable option for UIT application. The “AASHTO LRFD Bridge Construction Specifications” was modified as such in the 2020 Interim Revisions released in September of 2019.
