... the thermal history during welding. While multi-pass welds have successfully achieved CVN values greater than 66.4 ft-lbs (90 J) at the fusion line, this work explores the use of single-OD welds to achieve similar toughness values. Thus, single OD-pass submerged arc welding (SAW) test specimens were produced...
