Abstract
The present disclosure relates to methods for forming a golf club head assembly comprising a golf club head body and a high strength faceplate. The high strength faceplate can be heat treated. After welding the faceplate to the club head body, vibrational waves can be used to relive stress in the weld heat affected zones of the golf club body and faceplate.
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 faceplate under a 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;
- (d) after heating the faceplate from step (c), allowing the faceplate to cool in an inert gas environment;
- (e) aligning the faceplate of step (a) with the club head body of step (b) after heating step (c) and cooling step (d);
- (f) welding the faceplate to the club head body to form a heat affected zone (HAZ) between the faceplate and the club head body to form a golf club head assembly;
- and
- (g) relieving stress of the HAZ of the golf club head assembly by 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 selected from the group consisting of:
- a faceplate, a front portion, a back portion, a lower back portion, a bottom portion, and a hosel 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 solvus temperature of the welded portion for a predetermined amount of time;
- (d) after heating the welded portion from step (c), allowing the welded portion to cool in an inert gas environment;
- (e) aligning the welded portion of step (a) with the club head body of step (b) after heating step (c), and cooling step (d);
- (f) welding the welded portion to the club head body after step (e) to form a heat affected zone (HAZ) between the welded portion and the club head body to form a golf club head assembly;
- and
- (g) relieving stress of the HAZ of the golf club head assembly by using vibrational waves.
