Abstract:
1. A method for performing, ultrasonic testing using an ultrasonic testing system, the method comprising the steps of: positioning an ultrasonic transducer and a delay line on an outer wall of a test object; firing said ultrasonic transducer to generate an ultrasonic pulse that passes through said delay line and through said test object, a portion of said ultrasonic pulse being reflected back from an interface between said delay line and said outer wall of said test object; measuring a delay echo time of flight, wherein said delay echo time of flight is the time it takes for said ultrasonic pulse to travel from said ultrasonic transducer to said interface between said delay line and said outer wall of said test object and back as said reflected portion of said ultrasonic pulse; determining the temperature of said delay line based on only one time of flight measurement of said ultrasonic pulse that passes through said delay line, said only one time of flight measurement consisting of said delay echo time of flight; and determining the temperature of said test object based on the temperature of said delay line.
