Nondestructive Testing (NDT)

Fish & Associates, Inc. has a team of Level I, II and III ASNT NDT technicians who specialize in magnetic particle (MT) and ultrasonic (UT) .

Ultrasonic phased array (PAUT) is the latest generation of UT equipment designed to identify cracking or corrosion inside of fracture critical components, connections, or welds that would not be identifiable by visual observation alone. Our team is currently working with several clients to introduce PAUT in the transportation industry.

Another technology that we provide is ultrasonic impact treatment (UIT), which can extend the life of a serviceable fillet weld by relieving stresses at the critical elastic/plastic zone of the weld toe.

  • Certified Bridge Inspectors (CBI)
