Preparation and evaluation of submerged-arc weld in 4 inch thick 3Cr-1. 5Mo-0. 1V steel plate. Final report

Technical Report ·
OSTI ID:5362682
A 79-pass submerged-arc weld joint was prepared in a 4-inch thick 3Cr-1.5Mo-0.1V steel plate using welding wire with a composition similar to the base plate. Welding was made without difficulty, and no cracking was observed after stress relieving at 1175 F (635 C) for 4 hours. After stress relieving to tensile strength levels of 80 to 110 ksi (550 to 760 Mpa), tensile and Charpy impact properties of the weld metal and the heat-affected zone (HAZ) were determined. The HAZ exhibited virtually the same tensile strength and toughness as the base plate. The weld metal exhibited somewhat lower toughness, while its tensile strength was equivalent to that of the base plate.
