Abstract
Preliminary investigation on impression creep behaviour of different zones (base metal, weld metal and Heat Affected Zone) of similar and dissimilar Cr-Mo steel welded joints in as welded and PWHT conditions has been attempted. It has been possible to evaluate the steady state creep rate of different zones and PWHT has shown a detrimental effect on the impression creep resistance of all weldments.
