Recent Information on Weld Metal

Abstract

In the wide international field of 'weld metal' research, the most significant to our mind has been the work concerned with its microstructure : how the microstructure is constituted ; how it is affected by chemistry and welding procedures ; what is the relation between weld metal microstructure and toughness. Of no less importance are the investigations relating to non-metallic inclusions : their extent, composition and effect on toughness. These aspects have been highlighted here.
