    摘要： Provided are butt welds and methods of making such butt welds using a combination of fusion root welding and friction stir welding to yield welds with decreased propensity for dropout during friction stir welding without the need for a back-up support plate. In one form of the present disclosure, the butt weld includes: two or more abutting structural steel components beveled on faying surfaces on one side of the components to form a suitably shaped fusion root weld groove and unbeveled on faying surfaces on the opposite side of the components and interconnected with a first fusion root weld on the beveled side of the components and a second friction stir weld on the unbeveled side of the components, wherein the first fusion root weld has a width ranging from 7 mm to 30 mm, a penetration depth ranging from 2 mm to 20 mm, and an overfill ranging from 2 mm to 5 mm, and wherein the stir zone of the second friction stir weld penetrates the first fusion root weld. The butt welds and methods of making find application in joining linepipe for oil and gas production.

    摘要： Provided are strain hardened high strength nickel based alloy welds that yield improved properties and performance in joining high strength metals. The advantageous weldments include two or more segments of ferrous or non-ferrous components, and fusion welds, friction stir welds, electron beam welds, laser beam welds, or a combination thereof bonding adjacent segments of the components together, wherein the welds comprise a strain hardened nickel based alloy weld metal composition including greater than or equal to 10 wt % Mo based on the total weight of the nickel based alloy weld metal composition. Also provided are methods for forming the welds from the nickel based alloy weld compositions. The strain hardened high strength nickel based alloy welds are useful in the oil, gas and petrochemical industry in applications for natural gas transportation and storage, oil and gas well completion and production, and oil and gas refinery and chemical plants.
