ABSTRACT:
A method of forming an orthopaedic implant having a porous surface, the method including the steps of providing a porous surface including a porous layer attached to a substantially solid layer; positioning the porous layer on the orthopaedic implant; providing a high energy density welding device capable of producing a high energy density weld beam; and forming a weld bead substantially about the periphery of the porous layer by directing the high energy density weld beam about the periphery of the porous layer, wherein the weld bead bonds the porous layer to the implant. Two shaped porous pads may also be welded together about an implant body to avoid welding the body itself.
