Abstract
A method of forming a golf club head assembly includes aligning a faceplate with a recess of a club head; welding the faceplate to the club head; then, after welding the faceplate, heating the club head and the faceplate to at least a solvus temperature of the faceplate for a predetermined amount of time; and then, after heating the club head and the faceplate, allowing the club head and the faceplate to air cool.
Claims20
A method of forming a golf club head assembly, the method comprising:
- (a) providing a faceplate formed from an α-62 titanium alloy, the α-62 titanium alloy comprising between 2 wt % to 10 wt % aluminum (Al);
- (b) aligning the faceplate with a recess of a club head;
- (c) welding the faceplate to the club head;
- (d) heating the club head and the faceplate to a temperature that is greater than the solvus temperature of the faceplate for a predetermined amount of time;
- and
- (e) allowing the club head and the faceplate to cool in an inert gas,
- wherein step (d) is performed at a temperature of at least 580° C.
A method of forming a golf club head assembly, the method comprising:
- (a) providing a faceplate formed from an α-62 titanium alloy, the alloy having a solvus temperature;
- (b) aligning the faceplate with a recess of a club head;
- (c) welding the faceplate to the club head;
- (d) heating the club head and the faceplate to a temperature that is greater than the solvus temperature of the faceplate for a predetermined amount of time;
- and
- (e) allowing the club head and the faceplate to cool in an inert gas,
- wherein the club head assembly substantially maintains its bulge and roll curvature after 2,000 golf ball strikes.
A method of dispersing stresses in the weld-metal heat affected zone (HAZ) of a faceplate welded to a golf club head, the method comprising:
- (a) heating the club head and the faceplate to a temperature that is greater than the solvus temperature of the faceplate for a predetermined amount of time;
- wherein the faceplate is formed from an α-62 titanium alloy, the α-62 titanium alloy comprising between 6.5 wt % to 8.5 wt % aluminum (Al), 1.0 wt % to 2.0 wt % vanadium (V), 0.20 wt % or less oxygen (O), and 0.20 wt % or less silicon (Si).
