1. An additive manufacturing system for joining a first work piece to a second work piece that is composed of a different material than the first work piece, the additive manufacturing system comprising:
an additive manufacturing tool configured to receive one or more metallic anchoring materials;
a power source configured to provide electrical power to the one or more metallic anchoring materials to melt the one or more metallic anchoring materials into a plurality of droplets, the additive manufacturing tool being configured to deposit the plurality of droplets; and
a controller configured to control the additive manufacturing tool or the power source to fasten, via the plurality of droplets, a first work piece to a second work piece, wherein the controller is configured to:
control the additive manufacturing tool or the power source to apply the plurality of droplets at a surface of a first work piece via an opening formed in the second work piece to build up a part that is shaped to join the first work piece and the second work piece without melting the second work piece, and
control the power source to provide DC or AC power in the form of a pulsed welding current waveform.
