Abstract
The primary objective of this study was to provide an assessment of the weld metal and heat-affected zone fracture behaviour for a series of submerged-arc welds produced in HY100 and HSLA100 steels. The toughness evaluation was carried out using one-inch (25mm) thick dynamic tear (DT) fracture resistance specimens tested over a range of temperatures in order to establish weldment transition behaviour. The welds investigated were prepared using the sane nominal energy input (2 kJ/mm) and included two submerged-arc narrow-gap (HY-SAW(NG) and HSLA-SAW(NG)) and a conventional submerged-arc weld (HSLA-SAW).
