Dept. of TransportationWilkinson, StuartUniversity of South FloridaUS Transportation CollectionTo ensure that Florida bridges remain safe and structurally secure for their 50-year-plus service life, they are inspected regularly. For steel bridges, welds critical to the bridge\ue2\u20ac\u2122s integrity do not even leave the workshop unless they meet rigorous standards governed by the American Welding Society\ue2\u20ac\u2122s Bridge Welding Code (AWS Standard D1.5). To detect flaws without damaging the weld, the code requires use of nondestructive testing (NDT), either radiographic testing (RT) or conventional ultrasonic testing (UT)
