Abstract
A golf club head with a mitered joint for joining components of dissimilar materials is disclosed herein. The golf club head has a body with an internal edge defining a recess, and a face component having an internal edge. The face component is disposed over the recess. The internal edge of the body and the internal edge of the face have an angle ranging from about 10 degrees to about 80 degrees.
Claims17
A method for joining iron-type golf club head components, the method comprising:
- applying a copper-based filler material to a first attachment surface of an iron-type body to create a copper-based filler material attachment surface of the iron-type body, the iron-type body having an internal edge defining a recess, the first attachment surface formed continuously around an entire perimeter portion of the iron-type body, wherein the iron-type body is consisting essentially of a steel;
- positioning a second attachment surface of a single material face component over the copper-based filler material attachment surface of the iron-type body, the face component disposed over the recess, wherein the face component is consisting essentially of a titanium alloy;
- and
- performing at least one brazing cycle within a vacuum brazing furnace to braze the face component to the iron-type body, wherein the at least one brazing cycle comprises reaching a maximum vacuum level within the vacuum brazing furnace, increasing a temperature within the vacuum brazing furnace to a maximum temperature while at the maximum vacuum level, dropping the temperature to a minimum temperature while reducing the vacuum level;
- wherein a miter joint is formed between the second attachment surface of the face component and the first attachment surface of the iron-type body and has an angle ranging from 10 degrees to 80 degrees relative to a plane of a rear surface of the face component,
- wherein the second attachment surface of the face component is formed continuously around an entire circumference of the rear surface of the face component,
- wherein the second attachment surface of the face component has a width ranging from 0.04 inch to 0.5 inch,
- wherein the first attachment surface of the iron-type body has a width substantially matching the width of the second attachment surface of the face component, and
- wherein the copper-based filler material is a copper alloy consisting essentially of copper, manganese and nickel.

- positioning a second attachment surface of a single material face component over the copper-based filler material attachment surface of the iron-type body, the face component disposed over the recess, wherein the face component is consisting essentially of a titanium alloy, wherein the second attachment surface comprises a first section, a second section and at least one transition section corresponding to the first section, the second section and the at least one transition section of the first attachment surface;
- and
- performing at least one brazing cycle within a vacuum brazing furnace to braze the face component to the iron-type body, wherein the at least one brazing cycle comprises reaching a maximum vacuum level within the vacuum brazing furnace, increasing a temperature within the vacuum brazing furnace to a maximum temperature while at the maximum vacuum level, dropping the temperature to a minimum temperature while reducing the vacuum level;
- wherein a miter joint is formed between the second attachment surface of the face insert and the first attachment surface of the iron-type body and has a first angle ranging from 10 degrees to 80 degrees relative to a plane of a rear surface of the face insert,
- wherein the first angle of the first section of the first attachment surface and the first section of the second attachment surface has is greater than a second angle of the second section of the first attachment surface and the second section of the second attachment surface,
- wherein the at least one transition section has a third angle with a value between the first angle and the second angle, and
- wherein the copper-based filler material is a copper alloy consisting essentially of copper, manganese and nickel.
