Description	P92 steel is tungsten-modified creep-resisting steel with 9% chromium content alloyed. Comparing grade P91 (according to ASTM code A335), its creep resistance is improved by adding 1.6% of tungsten and 0.058% of niobium. The microstructure of as-received steel (normalised and tempered) is formed by tempered martensite. The experimental similar weld joint was prepared by TIG and MMA welding methods. For microstructure assessment, light and electron microscopy, X-ray diffraction, ThermoCalc with Dictra, and Vickers hardness measurement were used. Microstructure of weld metal, HAZ, and base material of weld joint is described. In general, microstructure of weld joint is uniform formed by less or more tempered martensite.
