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 golf club head body under a heat treatment, wherein the golf club head body is heated to a temperature that is greater than a solvus temperature of the golf club head body for a predetermined amount of time;
- (d) after heating the golf club head body from step (c), allowing the golf club head body to cool in an inert gas environment;
- (e) aligning the faceplate of step (a) with the golf club head body of step (b) after heating step (c) and cooling step (d);
- (f) welding the faceplate to the golf club head body to form a heat affected zone (HAZ) between the faceplate and the golf 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 an iron-type club head body formed from a second material, wherein the first material is different than the second material,
- (c) heating the iron-type club head body under a heat treatment, wherein the iron-type club head body is heated to a temperature that is greater than a solvus temperature of the iron-type club head body for a predetermined amount of time;
- (d) after heating the iron-type club head body from step (c), allowing the iron-type club head body to cool in an inert gas environment;
- (e) aligning the welded portion of step (a) with the iron-type club head body of step (b) after heating step (c), and cooling step (d);
- (f) welding the welded portion to the iron-type club head body after step (e) to form a heat affected zone (HAZ) between the welded portion and the iron-type 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.
