The influence of filler material composition on the residual stress distribution in similar and dissimilar gas tungsten arc weldments of maraging steel and medium alloy medium carbon steel has been investigated. In the fusion zone, residual stresses are compressive in similar metal welds of maraging steel and tensile in similar metal welds of medium alloy medium carbon steel. In the dissimilar metal welds, the nature of residual stresses in the weld varied from compressive in maraging steel to tensile in medium alloy medium carbon steel. The magnitude of residual stresses decreased when the maraging steel is taken in soft condition in the dissimilar metal welds. Post-weld aging resulted in lowering of residual stresses in medium alloy medium carbon steel.
