  • Apparatus and method of discriminating flaw depths in the inspection of tubular products
    Patent number: 5085082
    Abstract: An apparatus and method for discriminating between flaw depths of 5% and 10% of the tube wall thickness of electric resistance welds are disclosed. At least two electromagnetic acoustic transducers (EMATs) are employed to generate ultrasonic surface and shear waves. A logic circuit discriminating means selectively activates an alarm for flaw depths of about 10% or greater, but does not activate the alarm for flaw depths of about 5% or less, thereby avoiding waste in time and materials.
