The microstructure of welds are fascinating to study metallographically as they usually consist of regions that are cast and wrought with variations in grain size and shape, and the potential for a wide variety of microstructures (depending upon the alloy composition) and hardnesses. The talk will illustrate weld microstructures in a wide variety of metals and alloys and by a wide variety of processes. Emphasis will be on the use of selective etchants and color techniques.
