Friction welding fusion enhancer apparatus

A friction welding fusion enhancer apparatus which can be utilized with a wide range of friction welder machines for increasing the fusion area of a rotatable workpiece to be friction welded to a substrate workpiece, of either similar or dissimilar materials, for the purpose of achieving greater strength than achieved with conventional methods, while limiting the build-up of plastisized matter around the peripheral edge of the rotatable workpiece in an operation comprising a burnoff, upset, forging, fusing and apparatus removal phases, said apparatus comprising:

• an engagement means for engagement with a chuck of said friction welding machines to permit holding of said friction welding fusion enhancer apparatus during said burnoff, upset, forging, and fusing phases;
• a reaction surface area greater than said rotatable workpiece is made part of said friction welding fusion enhancer apparatus and further said reaction surface area is located axially 180 degrees from said rotatable workpiece engagement end and further said reaction surface area is removable;
• an integral geometry can comprise said friction welding fusion enhancer apparatus and further said integral geometry includes said engagement means, said reaction surface area and a break-a-way or burn-a-way removable section after completion of said burnoff, upset, forging, and fusing phases after removal of said apparatus from said chuck;
• a componentized configuration comprising said engagement means, an attachment holding mechanism and said reaction surface area that is removable from said chuck, after completion of said burnoff, upset, forging, and fusing phases;
• and
• said friction welding, fusion enhancer apparatus reaction surface area provides for extending the heat past the outer diameter of said rotatable workpiece and further permits the fusion bonding of a greater area of said rotatable workpiece by extending plastisizing of materials, which would not occur without said friction welding fusion enhancer apparatus and further said reaction area can be held in place with an attachment holding mechanism during said burnoff, upset, forging, and fusing phases.
