ActiveUS7348523B2Increase ratingsFast formingFurnaces without endless coreArc welding apparatusOperating temperature rangeEngineering
A shear-assisted solid state welding method for joining of metal parts, involves a first step of heating opposing surfaces in a non-passivating environment to a temperature in the hot working temperature range of the metal. A second step involves bringing the opposing surfaces into contact while still in the hot working temperature range, and applying compressive stress sufficient to substantially prevent sliding in response to shear displacement, causing plastic flow in the hot layers. A third step involves imposing relative shear displacement of the metal work pieces without disengaging the opposing surfaces. The shear displacement induces plastic shear strain within the hot layers to progressively induce bonding.
