Abstract

A method for forming a golf club head having a volume of approximately 460 cubic centimeters, the method comprising the steps of casting a face component, attaching a bonding flange, stamping a metal sheet of titanium alloy to form a sole component, welding the sole component to the face component to create a golf club head subassembly having a weld line of approximately six inches and polishing the weld line.

Claims

1. A method for forming a golf club head, the method comprising:

casting a face component, the face component comprising a striking plate section and a return section;

welding a bonding flange to the return section of the face component;

stamping a metal sheet to form a sole component;

welding the sole component to the face component to create a golf club head subassembly having a weld line;

polishing the weld line;

compression molding a crown component from a non-metal compound, the crown component having a bonding flange;

bonding the crown component to the golf club head subassembly using an adhesive to create an unfinished golf club head; and

finishing the unfinished golf club head to create a golf club head.

2. The method according to claim 1 wherein the bonding flange is composed of a titanium alloy material.

3. The method according to claim 1 wherein the bonding flange is composed of a stainless steel material.

4. The method according to claim 1 wherein the bonding flange is composed of an aluminum alloy material.

5. The method according to claim 1 wherein the bonding flange is composed of a magnesium alloy material.

6. The method according to claim 1 wherein the face component and the bonding flange are composed of a titanium alloy material.

7. The method according to claim 1 wherein the face component and the bonding flange are composed of a stainless steel material.
