Within the last decade there has been an increasing awareness that use of standards deeply notched fracture mechanics test specimens can result in substantial over-or-under-assessments of the real fracture toughness associated with shallow surface cracks.EXPERIMENTAL PROCEDURE Multipass submerged arc welds (SAW) were prepared on 30 mm thick low carbon HSLA pipeline steel plates under atmospheric condition. The repair welding procedure was simulated for toe and embededanbsp;...
