Abstract: A method of brazing golf club components composed of dissimilar materials, and particularly titanium and steel materials, is disclosed herein. The method includes the steps of preparing surfaces of the components for brazing, applying to at least one of the surfaces a nickel-based filler, fixturing each of the first and second golf club components within a vacuum brazing furnace so that the surfaces face one another, and performing at least one brazing cycle within the vacuum brazing furnace.

Abstract: An iron-type golf club head with a hosel, a hosel bore, and an exit channel in communication with the hosel bore that is offset from and extends at an angle of up to 15 degrees with respect to the hosel bore is disclosed herein. The exit channel does not extend into the face or sole of the golf club head, thereby preserving the structural integrity and aesthetics of the golf club while permitting the use of adjustable hosel features that allow for easy adjustments to the loft and lie of the club head. This feature may be used in connection with any type of irons, including wedges.

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.

Abstract: A method for transient liquid phase bonding golf club head components is disclosed herein. Golf club components composed of dissimilar materials are joined using transient liquid phase bonding. One embodiment of the transient liquid phase bonding process joins a steel component to titanium component using a pure copper interlayer heated between the temperature of 870° C. to 1085° C. The interaction between the titanium and the copper forms a eutectic below the melt temperature of pure copper, transitions to a liquid phase, and joins the titanium component to the steel component upon cooling.

Abstract: Methods of joining dissimilar metal, non-cylindrical golf club components, and particularly golf club bodies and faces, using one or more solid state processes are disclosed herein. One method includes the steps of preparing a first non-cylindrical golf club component made of a first metal material, preparing a second non-cylindrical golf club component made of a second metal material that is different from the first metal material, and affixing the first non-cylindrical golf club component to the second non-cylindrical golf club component along a plane using a solid state joining process. Another method includes the steps of providing a golf club body with a first planar joining surface, providing a golf club face component with a second planar joining surface, and affixing the first planar joining surface to the second planar joining surface via linear friction welding, rotational friction welding, diffusion bonding, or ultrasonic welding.
