Sažetak
This article deals with the new results from measurement of mechanical properties of P92 welded joints. Tested welded joints of P92 steel were prepared using Gas Tungsten Arc Welding (GTAW) for root layer in combination with Manual Metal Arc Welding (MMAW) for filler layers. After the welding, the different modes of Post Weld Heat Treatment (PWHT) were made and the values of hardness, tensile strength and impact toughness of weld metal and Heat-Affected Zone (HAZ) were measured.
