Abstract: A method and apparatus for joining using friction and current, wherein the friction/current joining apparatus includes a friction device, a forging device, an electrical current source, and a programmable controller, as well as workpiece holders for the workpieces to be joined. The friction/current joining apparatus is controlled such that, in a contacting phase, the workpieces are initially moved along a process axis, and their mutually facing joining surfaces oriented transverse to a common process axis are brought into contact. In a grinding phase, while subjected to contact pressure by mutual relative movement, the joining surfaces, are ground together and made smooth. At the end of the grinding phase, the relative frictional movement is permanently stopped and, in a forging phase following the grinding phase, the workpieces are pressed together, plasticized, and joined while subjected to contact pressure on their contacting joining surfaces along the process axis, and subjected to conductive heating with electrical current.

Abstract: A method of additive manufacturing, including: placing a layer (10) of strip-cast superalloy sheet material over a subcomponent (12) leaving a gap (20) between the layer and the subcomponent; and creating a weldment (14) to the layer. Shrinkage in the layer caused by the weldment is accommodated by a decrease in the gap with reduced shrinkage stress in the weldment. The layer may be formed of more than one piece (16), and the weldment may join the pieces together with or without joining the layer to the subcomponent. The gap may again grow due to differential thermal expansion when the resulting component is placed into service, thereby functioning as a passively regulated cooling channel.

Abstract: A welding apparatus for a controlled welding of steel cord ends. The welding apparatus allows for a controlled welding path from welding period over post-weld period to complete cool-down. In the welding apparatus a direct current source is controlled over time using a programmable controller. By sensing the voltage over the clamps of the welding apparatus and using this as a further input to the programmable controller, a constant power dissipation between the clamps can be achieved in the post-weld period. An associated method for making the weld where during the post-welding period the electric power dissipated between the clamps is held constant. The welds obtained by this procedure have a favourable metallographic structure in that the heat affected zone has more than 50% of pearlite and/or bainite over the total area of that zone.
