    Abstract: Weld metals and methods for welding ferritic steels are provided. The weld metals have high strength and high ductile tearing resistance and are suitable for use in strain based pipelines. The weld metal contains retained austenite and has a cellular microstructure with cell walls containing lath martensite and cell interiors containing degenerate upper bainite. The weld metals are comprised of between 0.02 and 0.12 wt% carbon, between 7.50 and 14.50 wt% nickel, not greater than about 1.00 wt% manganese, not greater than about 0.30 wt% silicon, not greater than about 150 ppm oxygen, not greater than about 100 ppm sulfur, not greater than about 75 ppm phosphorus, and the balance essentially iron. Other elements may be added to enhance the properties of the weld metal. The weld metals are applied using a power source with current waveform control which produces a smooth, controlled welding arc and weld pool in the absence of C0 2 or oxygen in the shielding gas.

    Abstract: A framework for determining or predicting the capacity of a structure. The framework includes predicting the capacity of the structure utilizing a physics-based prediction model. The prediction model may be constructed from a variety of numerical analysis approaches. The prediction model further incorporates at least one material physics process, at least one geometry description, and at least one limit state. The limit states may include collapse, tensile fracture, and buckling. The framework calls for validation of the predicted capacity of the structure via experimental verification or other methods. In some embodiments, the structure is a pipeline for producing hydrocarbons and the modes of operation may include parametric studies, Monte-Carlo type distributions, or stand-alone values.

    Abstract: At least one method, structure and apparatus used to measure tearing resistance of a commercial member. The method includes the use of full-scale testing methods and apparatuses to obtain unloading compliance measurements, which are used to generate a tearing resistance curve that includes the effects of geometry and considers data beyond the yield point of the commercial member. The commercial member may be a pipeline for carrying hydrocarbons.

    Abstract: Systems and methods for decreasing abrasive wear in a pipeline that is configured to transfer a slurry that includes a liquid and solid particles. The pipeline includes a pipe that defines a pipeline conduit and an energy dissipation layer that is within the pipeline conduit and through which a portion of the slurry flows. The slurry may flow at high velocity and/or with high turbulence, and it may contain hydrocarbons. The systems and methods may include an energy dissipation layer to decrease the kinetic energy of a buffer portion of the slurry that flows through the energy dissipation layer relative to the kinetic energy of a central portion of the slurry that flows through a central region of the pipe. This decrease in the kinetic energy of the buffer portion of the slurry may decrease abrasion of the pipe by the slurry.

    Abstract: A method and apparatus utilized in forming weld joint is described. In the method, a strength weld between two members is formed by a first welding process and a first weld metal. Then, one or more strain welds are formed by depositing a second weld metal adjacent to the strength weld using a second welding process. The strain welds are configured to form a weld joint having a specific minimum height and width to handle tensile strain to a specific strain capacity.
