Industry has long been cognizant of the fact that many of the problems arising in weldments can be attributed to microstructural changes occurring during the welding cycle. Stresses are imposed on a steel by non-uniform dimensional changes and by the transformation of austenite upon cooling. These stresses influence the weldability of the steel to an extent characteristic of the subject steel. Investigation of the transformation characteristics of various steels would enhance the understanding of their behavior during welding.
