Abstract: A golf-club head has a first half of shaped crown integrally including skirt and a hosel connection having a hosel attachment opening. A second half is a bottom plate having an integral striking face with built-in angle of loft so that the two halves are welded together providing solder leakage concentrating on the lower part of the head. A hosel is welded to the crown at the hosel connection.

Abstract: A golf-club head has a super plastically shaped crown integrally including sidewalls and a hosel connection having a hosel attachment opening. A bottom plate is welded to the crown and allows solder leakage concentrating on the lower part of the head. A super plastically shaped striking face is welded to the crown. A hosel is welded to the crown at the hosel connection.

Abstract: A method of making a titanium golf club head includes steps. One adopts Ti-4-6 Titanium alloy as SPDF material under isothermal forging conditions, sets the SPDF temperature at between 870-970 degrees Celsius, while heating the molds and workpieces simultaneously in a high frequency stove. One also moves the molds and workpieces from the stove to the forging machine, adjusting the forging machine reacting speed rate within the range of 10?2/s to 10?4/s.

Abstract: A metallic golf club wood head includes a face crust, a crown crust and a sole and side crust combined together with a hosel, wherein a face-enhancing member is integrally extended from a front edge of the crown downwardly or from a front edge of the sole and side crust upwardly and the face crust can be precisely and easily mounted on the face-enhancing member. Moreover, the loft angle of the face crust can be adjusted simply by altering the inclined angle of the face-enhancing member, which can be easily adjusted by simply folding inwardly or outwardly with respect to the crown crust or the to sole and side crust. In addition, the face-enhancing member is positioned with respect to the sweet spot of the face crust so as to better support and enhance impacting of the sweet spot.
