Systems and methods for integrated welding of metal materials

A welding system comprising:

• a transducer for generating mechanical vibrations in response to one or more first voltages;
• a first power supply electrically coupled to the transducer and providing the one or more first voltages to the transducer;
• wherein the generated mechanical vibration is mechanically coupled from the transducer to multiple workpieces having:
• an oxide layer located at an interface between the multiple workpieces, and
• impedances associated with each of the multiple workpieces
• a heat generation circuit for generating electrical current in response to one or more second voltages, the heat generation circuit comprising a power transformer, a capacitor bank, and a pulse transformer;
• a second power supply electrically coupled to the heat generation circuit and providing the one or more second voltages to the heat generation circuit;
• wherein the generated electrical current is directed from the heat generation circuit to the multiple workpieces;
• a workpiece mount mechanically coupled to the transducer and electrically coupled to the heat generation circuit, the workpiece mount including electrodes mechanically coupling the generated mechanical vibration and electrically coupling the generated electrical current to the multiple workpieces;
• and
• a controller for controlling timing of the transducer and the heat generation circuit.
