Abstract
The present invention relates to a golf club head casting provided with an internal perimetral welt about the club face. During the club head casting process, the thermomechanical behavior of the casting allows differential cooling across the club face. The face cools at a different rate than the welt, thereby allowing the exterior surface of the face to be maintained in a generally convex shape. Thus, a close-tolerance casting that conforms to preselected face tolerance specifications may be produced.
