Abstract
The present disclosure relates to methods for forming a golf club head assembly using a combination of different, but separate heat treatments for the golf club head body and high strength faceplate, and vibrational waves to relive stress in the weld heat affected zones of the golf club body and face.
Claims20
A method of forming a golf club head assembly, the method comprising:
- (a) providing a faceplate formed from a first material,
- (b) providing a golf club head body formed from a second material, wherein the first material is different than the second material,
- (c) heating the club head body under a first heat treatment, wherein the club head body is heated to a temperature that is greater than a solvus temperature of the club head body for a predetermined amount of time,
- (d) heating the faceplate separately from the club head body under a second heat treatment, wherein the second heat treatment is different than the first heat treatment, wherein the faceplate is heated to a temperature that is greater than a solvus temperature of the faceplate for a predetermined amount of time;
- (e) after heating the club head body from step (c) and the faceplate from step (d), allowing the club head body and the faceplate to cool in an inert gas environment;
- (f) aligning the faceplate of step (a) with the club head body of step (b) after heating steps (c) and (d), and cooling step (e);
- (g) welding the faceplate to the club head body after step (f) to form a heat affected zone (HAZ) between the faceplate and the golf club head to form a golf club head assembly;
- and
- (h) relieving the stress of the HAZ of the golf club head assembly by using vibrational waves.

A method of forming an iron type golf club head assembly, the method comprising:
- (a) providing a welded portion formed from a first material, wherein the welded portion comprises at least one member of a group consisting of the faceplate, the front portion, the back portion, the lower back portion,
- (b) providing a golf club head body formed from a second material, wherein the first material is different than the second material,
- (c) heating the welded portion under a first heat treatment, wherein the welded portion is heated to a temperature that is greater than a solution temperature of the welded portion for a predetermined amount of time;
- (d) heating the golf club head body separately from the welded portion under a second heat treatment, wherein the second heat treatment is different than the first heat treatment, wherein the golf club head body is heated to a temperature that is greater than a solution temperature of the golf club head body for a predetermined amount of time,
- (e) after heating the welded portion from step (c) and the golf club head body from step (d), allowing the welded portion and the club head body to cool in an inert gas environment;
- (f) aligning the welded portion of step (a) with the club head body of step (b) after heating steps (c) and (d), and cooling step (e);
- (g) welding the welded portion to the club head body after step (f) to form a heat affected zone (HAZ) between the welded portion and the golf club head to form the golf club head assembly;
- and
- (h) relieving the stress of the HAZ of the golf club head assembly by using vibrational waves.
