Abstract
A golf club head having localized heat treatment is described herein. Other embodiments are disclosed.
Claims20
A golf club head comprising:
- a faceplate and a body, the body comprising a sole, a crown, a heel end, and a toe end;
- wherein:
- the sole is in a ground plane at address;
- the crown is opposite the sole;
- the heel end is opposite the toe end and perpendicular to the sole and the crown;
- the faceplate comprises a geometric center that is equidistant from the crown and the sole, and equidistant from the heel end and the toe end;
- and
- the faceplate defines a loft plane, wherein the loft plane intersects the ground plane and is tangent to the geometric center;
- the faceplate further comprises a region defined by a reference shape having a height and a width;
- wherein:
- the reference shape extends toward the crown and the toe end from the geometric center;
- a reference shape height is between approximately 5% and approximately 50% of a total height of the faceplate, measured within the loft plane, in a crown-to-sole direction;
- a reference shape width is between approximately 5% and approximately 25% of a total width of the faceplate, measured perpendicularly to the loft plane, in a heel end-to-toe end direction;
- the reference shape further comprises a threshold characteristic time value, and within the reference shape, one or more locations comprise a characteristic time value higher than the threshold characteristic time value;
- and
- the faceplate further comprises a first heat affected zone at or near the one or more locations, each heat affected zone location comprising a characteristic time value lower than or equal to the threshold characteristic time value, wherein;
- the first heat affected zone comprises a spot weld comprising a diameter between approximately 0.125 inch and 0.75 inch, and the first heat affected zone comprises a diameter between approximately 20% to 50% of the diameter of the spot weld,
- wherein the spot weld results in a characteristic time reduction;
- and
- a physical grain structure of the first heat affected zone is a dendrite microstructure.
