Method of bonding golf club head by brazing

Abstract

A method of making a golf club head, which the golf club includes a plurality of components, includes the steps of: coating a brazing solder on the components, then heating the components for solidification of the brazing solder to form a metal skin layer on each component, then bonding the components together by brazing.

1 . A method of bonding a golf club head, which the golf club includes a plurality of components and bonded together by brazing, wherein the components are provided with a metal skin layer on predetermined bonding portions respectively prior to brazing. 
   
   
       2 . The method as defined in  claim 1 , wherein the metal skin layer is made of a material chosen from gold, silver, platinum, palladium, copper, nickel, cobalt, chromium, aluminum, molybdenum, titanium, lead, tin, zinc, cadmium, or alloy of above or combination of above. 
   
   
       3 . The method as defined in  claim 1 , wherein a method of making the metal skin layer on the component includes electroplating, spray welding, sputtering, physical or chemical evaporation, and chemical plating. 
   
   
       4 . A method of making a golf club head, which the golf club includes a plurality of components, comprising the steps of: coating a brazing solder on the components, then heating the components for solidification of the brazing solder to form a metal skin layer on each component, then bonding the components together by brazing.
