Abstract: A method of resistance spot welding a workpiece stack-up that includes an aluminum workpiece and an overlapping adjacent steel workpiece so as to minimize the thickness of an intermetallic layer comprising Fe—Al intermetallic compounds involves providing reaction-slowing elements at the faying interface of the aluminum and steel workpieces. The reaction-slowing elements may include at least one of carbon, copper, silicon, nickel, manganese, cobalt, or chromium. Various ways are available for making the one or more reaction-slowing elements available at the faying interface of the aluminum and steel workpieces including being dissolved in a high strength steel or being present in an interlayer that may take on a variety of forms including a rigid shim, a flexible foil, a deposited layer adhered to and metallurgically bonded with a faying surface of the steel workpiece, or an interadjacent organic material layer that includes particles containing the reaction-slowing elements.

Abstract: This disclosure relates generally to welding and, more specifically, to electrodes for arc welding, such as Gas Metal Arc Welding (GMAW) or Flux Core Arc Welding (FCAW) of zinc-coated workpieces. In an embodiment, a welding consumable for welding a zinc-coated steel workpiece includes a zinc (Zn) content between approximately 0.01 wt % and approximately 4 wt %, based on the weight of the welding consumable. It is presently recognized that intentionally including Zn in welding wires for welding galvanized workpieces unexpectedly and counterintuitively alleviates spatter and porosity problems that are caused by the Zn coating of the galvanized workpieces.

Abstract: Embodiments of the present invention comprise a system and method to weld or join coated materials using an arc welding system alone, or in combination with a hot wire system, where the arc welding system uses a welding current having an AC current portion to build a droplet for transfer to the workpiece. In further embodiments, the workpiece is coated with a material, such as zinc, and the arc welding system uses an AC welding waveform which is capable of welding coated workpieces with little or no porosity or spatter and can achieve enhanced performance. Additional embodiments use an enhanced electrode to provide optimum porosity performance. Such embodiments allow for the welding of coated material with little or no porosity and spatter, and at a high welding rate.

Abstract: A method of repairing a metallic artefact (40) with an open defect in or on a metallic surface or substrate of the metallic artefact includes cold forging the open defect to close the open defect and thereafter laser cladding the cold forged defect with a plurality of laser clad beads (44) applied to the metallic surface or substrate to cover the cold forged defect with a cladded metal layer. Advantageously, in-situ repair of fluid-filled vessels, pipes or the like is made possible by the repair method, in some instances eliminates the need to shut equipment down thereby reducing downtime and the cost associated with lost production.

The resulting weld deposit may comprise a tensile strength greater than or equal to 70 ksi, a yield strength greater than or equal to 58 ksi, a ductility (as measured by percent elongation) of at least 22%, and a Charpy V-notch toughness greater than or equal to 20 ft-lbs at −20° F. The welding consumable may provide a manganese fume generation rate less than 0.01 grams per minute during the arc welding operation.

Abstract: The disclosure describes example techniques and assemblies for joining a first component and a second component. The techniques may include positioning the first and second component adjacent to each other to define a joint region between adjacent portions of the first component and the second component. The techniques may also include inserting a solid retainer material into the joint region through an aperture in one of the first component or the second component to form a mechanical interlock between the first component and the second component and sealing the aperture to retain the solid retainer material within the joint region. The solid retainer material includes at least one of a metal, a metal alloy, or a ceramic.
