Abstract
Ultrasonic flaw sizing based on signal analysis and classification techniques was applied to linear welding flaws of sizes ranging from 1mm to 3mm generated under controlled laboratory conditions. Over 400 ultrasonic signals were captured digitally at various positions along these linear flaws and analyzed by an advanced pattern recognition package with regard to flaw sizes. Very encouraging results were observed and in some cases 100% correct flaw sizing performance has been achieved.
