A friction stir welding apparatus is provided herein. More specifically, traditional friction stir welding requires a rotatable head that is forced against a plurality of work pieces to bond the same. The rotational and normal forces generated by the friction stir welding tool are generally reacted by a backing plate, anvil, mandrel or other mechanisms, such hardware are subject to the applied forces and are often supported with additional internal supports. Conversely, an apparatus for performing a friction stir weld is described that omits the need for such a backing member and internal supports as it is performed using a self reacting pin tool.

1. An apparatus for maintaining and selectively altering work pieces being bonded by friction stir welding, wherein the work pieces are abutted to form a seam, comprising: a first ring assembly for positioning on one side of the seam, comprising: an inner ring interconnected to an outer ring by way of a center ring;a plurality of clamp assemblies interconnected to a first surface of said center ring; anda plurality of plates interconnected to a second surface of said center ring;a second ring assembly for positioning on one side of the seam opposite from said first ring assembly, comprising: an inner ring interconnected to an outer ring by way of a center ring;a plurality of clamp assemblies interconnected to a first surface of said center ring; anda plurality of plates interconnected to a second surface of said center ring; andwherein said first ring assembly and said second ring assembly are used to facilitate bonding of the work pieces without an internal mandrel or any internal support for the work pieces being bonded. 2. The apparatus of claim 1, wherein said first ring assembly and said second ring assembly include pads that are used to contact the work pieces. 3. The apparatus of claim 1, wherein said first ring assembly is comprised of four selectively interconnected segments. 4. The apparatus of claim 1, further including a support ring positioned a predetermined distance from the seam, said support ring maintaining the position of said first ring assembly relative to the seam by way of at least one linking member. 5. The apparatus of claim 1, further comprising a plurality of selectively adjustable stands that support said lower ring assembly relative to the seam. 6. The apparatus of claim 1, wherein at least one clamp assembly of said plurality thereof includes a guide for engagement with at least one of said first plate and said second plate by way of an adjustable member associated with said at least one clamp. 7. The apparatus of claim 6, wherein said adjustable member is capable of moving the adjacent work pieces about 0.001 inches to about 1.0 inches. 8. The apparatus of claim 7 further including a measurement device that assesses the mismatch between each work piece. 9. The apparatus of claim 1, further comprising: a rotating tool for engagement into the seam, said rotating tool having a shoulder with a pin extending therefrom. 10. The apparatus of claim 9, wherein said rotating tool possesses a shoulder with a spiral pattern extending therefrom that terminates at said pin. 11. The apparatus of claim 9, wherein said pin is frustoconical, and has a first end and a second end, wherein said first end is interconnected to said shoulder, and said pin has a diameter at the first end that is larger than the diameter at the second end. 12. The apparatus of claim 10, wherein said spiral pattern includes a groove that facilitates the dissipation of heat. 13. An apparatus for maintaining and selectively altering work pieces being bonded by friction stir welding, wherein the work pieces are abutted to form a seam, comprising: a first ring assembly for positioning on one side of the seam and located on an external side of the work pieces, wherein said first ring assembly comprises:an inner ring interconnected to an outer ring by way of a center ring;a plurality of clamp assemblies interconnected to a first surface of said center ring;a plurality of plates interconnected to a second surface of said center ring;a second ring assembly for positioning on another side of the seam opposite of said first ring assembly and located on an external side of the work pieces; andwherein said first ring assembly and said second ring assembly is used to facilitate bonding of the work pieces without an internal mandrel or any internal support for the work pieces. 14. The apparatus of claim 13 wherein said second ring assembly comprises: an inner ring interconnected to an outer ring by way of a center ring;a plurality of clamp assemblies interconnected to a first surface of said center ring; anda plurality of plates interconnected to a second surface of said center ring. 15. The apparatus of claim 13, wherein said first ring assembly and said second ring assembly include pads for contacting the work pieces. 16. The apparatus of claim 13, wherein said first ring assembly is comprised of four selectively interconnected segments. 17. The apparatus of claim 13 further including a measurement device that assesses the mismatch between each work piece. 18. The apparatus of claim 13, further including a ring assembly positioned a predetermined distance from the seam, said ring assembly maintaining the position of said first ring assembly relative to the seam by way of at least one linking member. 19. The apparatus of claim 13, further comprising a plurality of stands that support said lower ring assembly relative to the seam. 20. The apparatus of claim 19, wherein said plurality of stands are selectively adjustable. 21. The apparatus of claim 13, wherein at least one clamp assembly of said plurality thereof includes a guide for engagement with at least one of said first plate and said second plate by way of an adjustable member associated with said at least one clamp. 22. The apparatus of claim 21, wherein said adjustable member is capable of moving the adjacent work pieces about 0.001 inches to about 1.0 inches. 23. An apparatus of claim 13, further comprising: a rotating tool for engagement into the seam, said rotating tool having a shoulder with a pin extending therefrom. 24. The apparatus of claim 23, wherein said rotating tool also includes a spiral pattern extending therefrom that terminates at said pin. 25. The apparatus of claim 23, wherein said pin is frustoconical, and has a first end and a second end wherein said first end is interconnected to said shoulder, and said pin has a diameter at the first end that is larger than the diameter at the second end. 26. The apparatus of claim 23, wherein said spiral pattern includes a groove that facilitates the dissipation of heat. 27. An apparatus for maintaining and selectively altering work pieces being bonded by friction stir welding, wherein the work pieces are abutted to form a seam, comprising: a first ring assembly for positioning on one side of the seam and located on an external side of the work pieces; anda second ring assembly for positioning on another side of the seam opposite of said first ring assembly and located on an external side of the work pieces, said second ring comprising: an inner ring interconnected to an outer ring by way of a center ring;a plurality of clamp assemblies interconnected to a first surface of said center ring; anda plurality of plates interconnected to a second surface of said center ring; and wherein said first ring assembly and said second ring assembly is used to facilitate bonding of the work pieces without an internal mandrel or any internal support for the work pieces.
