Abstract
A high Nickel based dissimilar metal weld (Alloy 182), known for its susceptibility to Primary Water Stress Corrosion Cracking (PWSCC), was investigated by fracture toughness tests in the ductile regime. One of
the key inputs for the structural integrity evaluation of components is determined by the maximum acceptable defect size that is based on the crack growth rates from fracture toughness specimens. Extensive
testing programs were carried out over the last years at SCK CEN and elsewhere and a large scatter of results is reported in literature. The scatter is related to the heterogeneous nature of the weld material, but
no full explanation is available yet. An overview of the obtained results is given as a function of the test temperature, the specimen orientation in the weld and the post-weld heat treatment (PWHT).
