ACOUSTIC EMISSION TESTING OF HIGH-STRENGTH STEEL WELDMENTS

Manual arc welds were made on high-strength ASTM A 514 and A 588 steels. Different weldment configurations were employed in order to vary the restraint on the welds during cooling. The weldments were monitored "in-cooling" with acoustic emission equipment. Weldments having greater restraint produced more acoustic emission, usually for longer periods of time. Weldments which fractured during cooling produced more acoustic emission than those which were unflawed. /Author
