Abstract
A golf club head manufacturing method, including: welding a first reinforcing piece with first thickness to a central portion between a toe and a heel, so as to extend along an edge of a face side of a sole part, the sole part being part of a lower part formed integrally with a side part; welding a second reinforcing piece of second, larger thickness to a central portion between the toe and heel so as to extend along the edge on the face side of the first piece; welding a face part to the first and second pieces from an inner space of the lower part; welding a hosel part to the lower and face parts; welding a crown part to the lower, face and hosel parts; and welding the lower and face parts together from the outside.
Claims9
A golf club head having a hollow structure, which is made of a metal, comprising:
- a lower part comprising a sole part and a side part which are integrally formed, the lower part further comprising a first reinforcing piece having a first thickness and a second reinforcing piece having a second thickness greater than the first thickness,
- wherein the first reinforcing piece is welded on an inner surface of the sole part in a substantially halfway portion between a heel side and a toe side of the sole part and is aligned with a face side edge of the sole part, and
- wherein the second reinforcing piece is welded on an inner surface of the first reinforcing piece in a substantially halfway portion between a heel side and a toe side of the first reinforcing piece and is aligned with a face side edge of the first reinforcing piece;
- and
- a face part welded to the sole part and the first and second reinforcing pieces of the lower part.
A method for manufacturing a golf club head having a hollow structure, which is made of a metal, comprising:
- welding a first reinforcing piece having a first thickness on an inner surface of a sole part of a lower part in a substantially halfway portion between a heel side and a toe side of the sole part so that the first reinforcing piece is aligned with a face side edge of the sole part, the sole part being integrally formed with a side part of the golf club head into the lower part;
- welding a second reinforcing piece having a second thickness greater than the first thickness on an inner surface of the first reinforcing piece so that the second reinforcing piece is aligned with a face side edge of the first reinforcing piece;
- welding a face part to the first and second reinforcing pieces from an inner side of the lower part to attach the face part to the lower part;
- welding a hosel part to the lower part and the face part;
- welding a crown part to the lower part, the face part and the hosel part;
- and
- welding the face part to the lower part from an outer side of the golf club head.
