ULTRASONIC TESTING OF FITTING ASSEMBLY FOR FLUID CONDUITS WITH A HAND-HELD APPARATUS

摘要

Hand-held apparatus and method for determining relative and/or absolute axia l position of a conduit end within a fluid coupling includes application of input ultrasonic energy in the form of transient shear waves and analyzing t he reflected energy. Application of the input energy collected at different radial positions about a first axial location is used with wavelet based correlation techniques to better analyze the reflected energy signals. Quali ty of the abutment between the conduit end and a surface associated with the coupling may also be determined as a separate or combined feature of the axi al position determination.
