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.
