The paper gives a survey of experimental results of fatigue crack growthrate measurement in a CrMoV pressure vessel steel weldments. Within the repairwelding technology project, the fatigue through-thickness, semi-elliptical surface crackgrowth rates measurement in weldments was carried out. Centre-Crack-Tension ( CCT) test specimens of two different rectangular cross-sections were machined from a Cr-MoV steel. Two welding technologies, manual metal arc and tungsten inert gas welding,were applied and specimens in as welded state and after heat treatment were tested atroom temperature. The crack growth rates were measured for both the base and weldmetals and also in the case of crack subsequent transition through all the weld zones.The crack growth rate of semi-elliptical surface cracks was evaluated and comparedwith the CCT 2D results.
