Abstract
In the brittle to ductile temperature transition regime fracture mechanics testing of ferritic weld metal from multilayer joints results in a wide scatter of toughness data. Results obtained from impact testing of V-notched and fatigue cracked Charpy-specimens as well as from static fracture toughness tests on small scale specimens show, that scatter of weld metal toughness data is systematic and can be related to material heterogeneity.
