1. An induction welding coil that comprises:
a spine that comprises a planar body that comprises opposing ends;
a pair of prongs that extend perpendicularly from the opposing ends of the spine, wherein each prong of the prongs comprise, respectively:
a planar body, wherein the spine and the pair of prongs are formed from a ferrite material to define a ferrite core; and
opposing ends, wherein one of the opposing ends of each prong abut an opposing end of the planar body of the spine, and at least one auxiliary piece extends perpendicularly from a middle portion of each prong, wherein the auxiliary piece comprises:
a planar shape; and
a ferrite material; and
a coil of wire that comprises a plurality of windings that surround the planar body of the spine.
