1. A system, comprising:
a first metal or alloy component with a first major surface; and
a second metal or alloy component with a second major surface, wherein the first major surface and the second major surface are adjacent to each other and define a joint region;
a metal or alloy powder disposed in at least a portion of the joint region;
a first current source electrically coupled in series to the first metal or alloy component and the first current source via a first external electrical conductor;
a second current source electrically coupled in series to the second metal or alloy component and the second current source via a second external electrical conductor;
a controller configured to:
cause the first current source to output a first alternating current that conducts through the first component adjacent to a first portion of the joint region to induce at least one of magnetic eddy currents or magnetic hysteresis within at least a first portion of the metal or alloy powder disposed in the first portion of the joint region; and
cause the second current source to output a second alternating current that conducts through the second component adjacent to a second portion of the joint region and induces at least one of magnetic eddy currents or magnetic hysteresis within at least a second portion of the metal or alloy powder disposed in the second portion of the joint region.
