The morphology and the crystallographic aspects of low carbon low ahoy weld metals have been investigated by mean of both optical and transmission electron microscopy. The ferrite morphology of the weld metal was characterized by the Grain Boundary Ferrite, Widman-statten Ferrite Side Plates, Acicular Ferrite and the Upper Bainite, and the transformation temperatures of these microstructures were examined. The Grain Boundary Ferrite and Ferrite Side Plates were transformed by the diffusion. It is confirmed that the Acicular Ferrite consisted of the bainitic ferrite transformed at many transformation sites, i.e., non-metallic inclusions. The WM-CCT diagram was proposed to represent the transformation characteristic of the weld metal.
