    摘要： A welding method and apparatus that simultaneously utilize laser beams and arc welding techniques. The welding apparatus generates a first laser beam that is projected onto a joint region between at least two workpieces to produce a first laser beam projection on adjacent surfaces of the workpieces and to cause the first laser beam projection to travel along the joint region and penetrate the joint region. The apparatus also generates an electric arc to produce an arc projection that encompasses the first laser beam projection and travels therewith along the joint region to form a molten weld pool. In addition, the apparatus generates a pair of lateral laser beams that produce lateral laser beams projections that are encompassed by the arc projection and are spaced laterally apart from the joint region to interact with portions of the weld pool that solidify to define weld toes of the weld joint.

    摘要： A load coupling for transmitting a torque load between a first shaft and a second shaft is disclosed. The load coupling may generally include a first shaft segment configured to be fixedly attached to the first shaft and a second shaft segment configured to be fixedly attached to the second shaft. The second shaft segment may be frictionally fit within the first shaft segment such that a frictional interface is defined between the first and second shaft segments. Additionally, the frictional interface may be configured such that the first and second shaft segments rotationally disengage when the torque load exceeds a torque threshold and rotationally reengage when the torque load is reduced to or below the torque threshold.

    摘要： A process for creating a near-surface cooling passage in an air-cooled turbomachine component. The process entails forming a channel in a surface of a surface region of the component so that the channel is open at the surface and fluidically connected to a first cooling passages within the component. A metallic layer is then deposited on the surface and over the channel without filling the channel. The metallic layer closes the channel at the surface of the surface region to define therewith a second cooling passage within the component that is fluidically connected to the first cooling passages. A coating system is then deposited on the metallic layer to define an outermost surface of the component. The second cooling passage is closer to the outermost surface of the component than the first cooling passages.
