In the present work temperature distributions and microstructure zones in single pass SMAW butt joints have been studied, using three-dimensional finite element analysis. Based on experiments on a semiautomatic machine, area of heat flux was calculated for moving heat source based modeling. Filler metal deposition was simulated using element birth and death method. The experimental results were compared with the modeled values. The model was further extended to pipe welded joints of 5 and 8 mm thicknesses for predicting the temperature distributions and microstructure zones.
