Description
A round robin investigation was made to determine if defects found using the non-destructive evaluation (NDE) techniques of ultrasonic phased array and x-ray inspection, can be identified by a real-time, feedback-based friction stir weld analysis tool (FSWAT) software and whether or not the results can be correlated. 30 panels of 6.3 mm thickness Al 2024-T351 aluminium alloy were butt welded using 5 different FSW tools with 10 different combinations of process parameters, each repeated three times. Each welded panel was also destructively tested using tensile specimens and metallographic examination. Probability of detection analysis curves were used to measure the reliability of the NDE techniques. Types of defects studied included microvoids and wormholes.
