Wood golf club head

Abstract

A wood golf club head has a sole plate, a crown, a strike face and a hosel that are all made of metal and are welded together. The sole plate is formed by forging to have different thicknesses at different parts and has a weight formed as a thicker part of the sole plate. Therefore, when the wood golf club head is manufactured, the shape, the size and the position of the weight is precisely set based on the design of the wood golf club head. Then the gravity center of the wood golf club head is accurately determined. Moreover, since the weight is directly formed on the sole plate without any gaps and the shape of the weight is simple and smooth, the wood golf club head performs a clear and pleasing striking sound while it strikes.

1 . A wood golf club head comprising:
 a sole plate made of metal excluding aluminum alloy, formed by forging to have different thicknesses at different parts and having
 an inner surface; 
 a weight formed as a thicker part of the sole plate and formed on and protruding from the inner surface without forming gaps between the weight and the inner surface and without touching a top edge, a front edge and an end edge of the sole plate; 
   a crown made of metal and welded on the top edge of the sole plate;   a strike face made of metal and welded between the front edge of the sole plate and a front edge of the crown; and   a hosel made of metal and welded between the end edge of the sole plate, an end edge of the crown and an end edge of the strike face.   
     
     
         2 . The wood golf club head as claimed in  claim 1 , wherein the metal, which is used to make the sole plate, the crown, the strike face and the hosel, is selected from a group consisting of titanium, stainless steel and carbon steel.
