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.

Claims (5)

1 . A method for joining iron-type golf club head components to form a golf club head, the method comprising:

applying five to eight grams of a copper-based filler material to a first attachment surface of a first component of the golf club head consisting essentially of 6-4 titanium alloy to create a first copper-based filler material attachment surface of the first component of the golf club head, wherein the first component is a face component, and wherein the copper-based filler material is a copper alloy consisting essentially of copper, manganese and nickel;

applying five to eight grams of the copper-based filler material to a second attachment surface of a second component of the golf club head consisting essentially of stainless steel to create a second copper-based filler material attachment surface of the second component of the golf club head, wherein the second component is an iron-type golf club body component;

fixturing, within a vacuum brazing furnace, the first copper-based filler material attachment surface of the first golf club component to face the second copper-based filler material attachment surface of the second golf club component; and

performing at least one brazing cycle within the vacuum brazing furnace to braze the first component to the second component, wherein 2.5 to 4 grams of the copper-based filler material remains in the golf club head.
