Ultrasonic Thickness Gauging (UTG) is a performing non-destructive method analysis of the local thickness of solid material and is based on the time taken by the ultrasound wave to return to the surface. UTG is frequently used to monitor metal thickness or weld quality in industrial settings such as mining.

EIWAA’s technicians are equipped with portable UTM probes to reach steel plating insides, tanks, decks, and the superstructure. They can read its thickness by simply touching the steel with the measurement head (transducer). Accuracy is generally assured by first removing visible corrosion scale.
