A weldability map has been developed for low alloy steels considering the role of carbon and the carbon equivalent of the alloying elements on hardness and hardenability. Contours of preheat temperatures are drawn based on the Seferian type of equation. On the basis of heat flow relations, heat input and the preheat temperature of the weld plate are related and trarisferred to the weldability map to include the heat input values and cooling time contours in the map.

Abstract


A weldability map has been developed for low alloy steels considering the role of carbon and the carbon equivalent of the alloying elements on hardness and hardenability. Contours of preheat temperatures are drawn based on the Seferian type of equation. On the basis of heat flow relations, heat input and the preheat temperature of the weld plate are related and trarisferred to the weldability map to include the heat input values and cooling time contours in the map.
