Abstract
When structural components are joined together by fusion welding the thermal cycle introduces changes in the microstructure between the base (or parent) material and the weld filler metal, [Easterling, 1983]. A typical weld consists of base, weld and heat-affected-zone (HAZ) metals, as shown in Figure 1. The HAZ is a transition region, which can be subdivided into a number of zones, which depend on the weld and base metals. Typical HAZ zones, shown in Figure 1, for a ferritic steel weld with matching weld and base metal compositions include a coarse grained (CGHAZ) zone adjacent to the weld metal, fine grained (FGHAZ) and intercriücal (ICHAZ) zones.
