The effect of metal initial elevated temperature on the microstructures and mechanical properties of a single pass arc welded steel plate were investigated. Hardness properties around the heat-affected zone (HAZ) were found to increase with metal preheat at 200°C while toughness and tensile strength of metal are found to decrease with an initial elevated temperature of welded specimens. The effects of initial elevated temperature on the mechanical properties are more pronounced around the fusion zone as compared with the base metal, as evidenced by the welded steel microstructures.

Abstract


The effect of metal initial elevated temperature on the microstructures and mechanical properties of a single pass arc welded steel plate were investigated. Hardness properties around the heat-affected zone (HAZ) were found to increase with metal preheat at 200°C while toughness and tensile strength of metal are found to decrease with an initial elevated temperature of welded specimens. The effects of initial elevated temperature on the mechanical properties are more pronounced around the fusion zone as compared with the base metal, as evidenced by the welded steel microstructures.
