Claims44
A golf club of wood-type having a hollow head body, comprising:
- a shaft;
- and
- a metal head attached to the shaft, wherein the metal head comprises a body having an opening in which a striking face member is disposed, the striking face member including a plurality of metal pieces;
- and
- wherein said plurality of metal pieces are fixed together by laser welding and press forming is performed on the plurality of metal pieces that are fixed together to form a curved surface portion of the striking face member.
A golf club of wood-type having a hollow head body, comprising:
- a shaft;
- and
- a metal head attached to the shaft, wherein the metal head comprises a body having an opening in which a striking face member is disposed, the striking face member including a portion formed through plastic working of a compounded metal plate fabricated through joining a plurality of metal pieces made of forged or rolled material by laser welding;
- and
- wherein the compounded metal plate is fabricated by fixing together by laser welding the metal pieces so that the metal pieces appear on an outside common surface of the striking face member of the head and the plastic working is performed on the compounded metal to form a curved surface portion of the striking face member.
A golf club of wood-type having a hollow head body, comprising:
- a shaft;
- and
- a metal head attached to the shaft, wherein the metal head comprises a plurality of metal pieces;
- and
- wherein the plurality of metal pieces are on an outside common surface of the head and are fixed together by welding, the welding process resulting in a smooth continuous outside common surface,
- wherein press forming is performed on the plurality of metal pieces that are fixed together by laser welding to form a curved surface of the outside common surface of the head.
A golf club of wood-type having a hollow head body, comprising:
- a shaft;
- and
- a metal head attached to the shaft, wherein the metal head comprises a body having an opening in which a crown member is disposed, the crown member including a plurality of metal pieces;
- and
- wherein the metal pieces appear on an outside surface of the crown member and are fixed together by laser welding and press forming is performed on the plurality of metal pieces that are fixed together to form a curved surface portion of the crown member.
A golf club of wood-type having a hollow head body, comprising:
- a shaft;
- and
- a metal head attached to the shaft, wherein the metal head comprises a body having an opening in which a side wall member is disposed, the side wall member including a plurality of metal pieces;
- and
- wherein the metal pieces appear on an outside surface of the side wall member and are fixed together by laser welding and press forming is performed on the plurality of metal pieces that are fixed together to form a curved surface portion of the side wall member.
A golf club of wood-type having a hollow head body, comprising:
- a shaft;
- and
- a metal head attached to the shaft, wherein the metal head comprises a body having an opening in which a sole member is disposed, the sole member including a plurality of metal pieces;
- and
- wherein the metal pieces appear on an outside surface of the sole member and are fixed together by laser welding and press forming is performed on the plurality of metal pieces that are fixed together to form a curved surface portion of the sole member.
