Method for ultrasonic testing of fitting assembly

A method for evaluating position of a conduit in a fluid coupling, comprising the steps of:

• assembling a body with an unthreaded end of a conduit;
• forming a fluid tight seal and grip against an outer surface of the conduit end;
• applying mechanical energy waves at a first location that is axially spaced from said conduit end;
• receiving return portions of said energy waves;
• and
• determining axial position of said conduit end in the body relative to said first location as a function of said received return portions of said energy waves.

A method for evaluating a fitting of the type having a conduit assembled at one end to a fitting comprising a body, a nut, and at least one ferrule, the method comprising the steps of:

• inserting an end of an unthreaded conduit into a fitting body;
• forming a fluid tight seal and grip against an outer surface of the conduit end;
• applying mechanical energy at a reference position that is axially spaced from the conduit end;
• detecting reflected mechanical energy;
• and
• determining, as a function of said reflected mechanical energy, axial position of the conduit end in the fitting body relative to the reference position.
