Abstract
An induction welding coil includes a spine having a planar body with opposing ends, and a pair of prongs extending perpendicularly from the opposing ends of the spine. Each of the prongs has a planar body, wherein the spine and the pair of prongs are formed from a ferrite material to define a ferrite core. The induction welding coil further includes a coil wire having a plurality of winding that surround the planar body of the spine.
Claims20
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.

A method for induction welding, the method comprising:
- positioning an induction welding coil at one side of components to be welded, the induction welding coil comprising a ferrite core and a pair of prongs extending perpendicularly from ends of a planar body, the ferrite core comprising:
- a spine comprising the planar body;
- and
- at least one auxiliary piece extending from each prong of the pair of prongs, the auxiliary pieces being planar and formed from a ferrite material;
- initiating induction welding of the components along a welding interface by applying a current to the induction welding coil to generate a magnetic flux;
- and
- moving the induction welding coil along the one side of the components to thereby inductively weld the components at the welding interface.

An induction welding system that comprises:
- a robot;
- an induction welding coil communicatively coupled to the robot, wherein the induction welding coil 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 comprises a planar body, wherein the spine and the pair of prongs are formed from a ferrite material to define a ferrite core;
- at least one auxiliary piece that extends from each prong of the pair of prongs, 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, wherein the robot is configured to control movement of the induction welding coil along only one side of components to be inductively welded to thereby melt a weld interface between the components.
