ABSTRACT:
Methods of welding two pieces of metal to produce a weld joint having excellent fracture toughness are provided. Two pieces of metal are positioned for welding so as to form a narrow weld groove having two sidewalls with bevel angles of less than about 10°. Two or more layers are applied to the weld groove to produce the weld joint such that the heat-affected-zone of the weld joint is substantially free of rogue grains.
