Fracture Toughness of Manual Metal-Arc and Submerged-Arc Welded Joints in Normalized Carbon-Manganese Steels


This paper shows that, in the temperature transition regime, scatter of weld metal and heat-affected zone toughness values is related to material heterogeneity in the welded joints. Results were obtained from impact testing of V-notched and fatigue-cracked Charpy specimens as well as from static fracture toughness tests on small-scale and full-thickness specimens. Besides material heterogeneity, mechanical heterogeneity is emphasized as having a significant influence on the fracture performance of heat-affected zone specimens.
