Conclusions
As the result of two heat treatments the structural heterogeneity, microhardness gradient in the seam and the base metal, and the residual internal stresses in weldments decreased considerably. The best properties were obtained after heat treatment 1: heating at a rate of 20 deg/h at 1050–1080°, holding 30 min, and furnace cooling to room temperature at a rate of 65 deg/h.
