Abstract
A system is disclosed that increases the efficiency of a weld inspector by reducing the amount of weld data that needs to be examined for any non-destructive (“NDT”) phased array and time-of-flight, diffraction ultrasonic testing of welds. The system reads ultrasonic testing data from an NDT scan of a series of metal welds and creates a table of target weld indications ranked by a series of filters representative of predetermined exclusion and significance criteria. The invention acts as a weld analysis concentrator by focusing the attention of an inspector on potential weld flaws that merit their attention, thereby increasing the efficiency of the inspector. The process typically reduces 95% to 98% of the ultrasonic weld testing data that must be reviewed by the inspector, while retaining flaw indications necessary for an inspector's competent review in conformity with various code requirements and regulations.
