ABSTRACT:
A method of fabricating a metal wood club head. The head is fabricated in two half-sections, each formed by a casting technique. Increased production throughput is achieved by the use of forming dies to maintain the shape of the two half-sections after removal from the casting molds, before the head half-section elements have fully hardened to a solid state. The two half-sections are subsequently joined by welding together facing edges of the respective half-sections along a parting line. The parting line extends through the highest point in the head crown, generally parallel to the face region and behind the hose. The placement of the parting line permits the use of simple one-piece mold cores, since there are no negative angles within the half-section elements to prevent such a core from being removed. The method is low cost, and provides a high strength club head, with the weld joint located away from club stress points.
