Abstract

A joining method for connecting heterogeneous metal parts includes the steps of: prefabricating a first connecting surface on a first metal part, and a second connecting surface on a second metal part; disposing at least one barrier layer on one of the first and second connecting surfaces of the first and second metal parts by a plating process; disposing a filler metal between the first and second connecting surfaces of the first and second metal parts such that the filler metal being sandwiched in-between the first and second metal parts; heating the filler metal disposed between the first and second connecting surfaces of the first and second metal parts; and cooling and solidifying of the molten filler metal connected between the first and second connecting surfaces of the first and second metal parts to constitute a golf club head.

Claims

1. A joining method for connecting heterogeneous metal parts of a golf club head comprising the steps of:

prefabricating a first connecting surface on a first metal part, and a second connecting surface on a second metal part;

disposing at least one barrier layer on one of the first and second connecting surfaces of the first and second metal parts;

disposing a filler metal between said at least one barrier layer and one of the first and second connecting surfaces of the first and second metal parts such that the filler metal being sandwiched in-between the first and second metal parts;

heating the filler metal disposed between said at least one barrier layer disposed on said one of the first and second connecting surfaces and the other of the first and second connecting surfaces of the first and second metal parts; and

cooling and solidifying of the molten filler metal connected between the first and second connecting surfaces of the first and second metal parts to constitute the golf club head.

2. The joining method for connecting heterogeneous metal parts of the golf club head as defined in claim 1, wherein the heterogeneous metal parts are selected from a striking plate, a weight member, a golf club head body, a hosel and a crown plate.

3. The joining method for connecting heterogeneous metal parts of the golf club head as defined in claim 1, wherein the heterogeneous metal parts are constructed from metals selected from one of titanium-based alloy, ferrous-based alloy, nickel-based alloy and copper-based alloy.

4. The joining method for connecting heterogeneous metal parts of the golf club head as defined in claim 1, wherein the barrier layer is constructed from one of chromium-based alloy, nickel-based alloy or vanadium-based alloy.

5. The joining method for connecting heterogeneous metal parts of the golf club head as defined in claim 1, wherein the barrier layer is formed on the connecting surface by a method selected from electroplating, electroless plating, physical vapor deposition (PVD), chemical vapor deposition (CVD) immersing and coating.

6. The joining method for connecting heterogeneous metal parts of the golf club head as defined in claim 1, wherein the barrier layer has a thickness ranging from 0.1 μ

m and 500 μ

m.

7. The joining method for connecting heterogeneous metal parts of the golf club head as defined in claim 1, wherein the filler metal is constructed from one of silver-based alloy, copper-based alloy, titanium-based alloy and nickel-based alloy.
