摘要： A method for creating a clad structure, comprising providing a substrate having an inner surface and an outer surface; providing a cladding material, wherein the cladding material is placed on the inner surface of the substrate, the outer surface of the substrate, or both; providing a surface activation material that is disposed between the substrate and the cladding material; providing at least one resistance welding device, wherein the at least one resistance welding device includes at least one electrode wheel that directly contacts the cladding material, and wherein the at least one resistance welding device generates resistance heating and pressure sufficient to melt the surface activation material and form a localized bond between the substrate and the cladding layer; and traversing the at least one electrode wheel across the cladding material and substrate to propagate the localized bond between the cladding material and the substrate and create a clad structure.

摘要： A method for creating metallic sandwich structures that includes providing at least two face sheets; providing at least two core sheets; orienting the core sheets relative to one another in a predetermined manner; and using indirect resistance roll brazing to join the core sheets to the face sheets to create a sandwich structure.

摘要： A capacitive discharge welding system includes at least one capacitive discharge-based power supply that is adapted to provide alternate polarity pulses from a first weld to a subsequent weld, and to be compatible with iron-core transformers used for alternating current resistance welding; at least one iron core transformer adapted to receive electrical discharges from the capacitive discharge-based power supply; a polarity switching network that includes at least two sets of silicon controlled rectifiers that are arranged in pairs for facilitating current flow in alternate directions; a pair of engagable, properly biased shunt diodes that are operative to shunt reflected current for protecting the silicon controlled rectifiers when the system is in use; and a control network configured for simultaneous engagement of the properly biased shunt diodes and firing the silicon controlled rectifiers for current flow; and tracking polarity for assuring that subsequent pulses use opposite direction current flow for preventing saturation of the iron core transformer.
