Abstract

A golf club head joining method is provided, which utilizes a soldering joining process to assemble the golf club head. The joining method includes the steps of providing a first component and a second component, wherein the first and second components are made of metal materials; subsequently, the step of applying a coating of active metal or compounds suitable to be affixed with a soldering metal material on the first component and the second component; and the last step of finally joining the first component to the second component, enabling the two to become one. Therefore, the joining method enables the joining of the golf club head not to be restricted to the use of certain materials and enhances the joint strength without incurring additional costs or complicating the manufacturing process.

Claims

1. A golf club head joining method, utilizing a soldering joining process for club head joint, comprising the steps of:

providing a first component, which is made of a metal material and has a joining surface;

providing a second component, which is made of a metal material and has a joining surface;

applying a coating of active metal or compounds suitable to be affixed with a soldering metal material on said first component and said second component;

wherein the surfaces of said first component and said second component are respectively coated with the layer of active metal or compounds capable of being affixed by said soldering metal material for joining; and

joining said first component and said second component, to join together said first component and said second component by adding said soldering metal material and then carrying out a heating process on said first component and said second component, to enable said soldering metal material to be melted into said joining surfaces between said first component and said second component, thereby joining said first component and said second component together.

2. The golf club head joining method as claimed in claim 1, wherein said first component is a high-melting-point metal and said second component is a low-melting-point metal, wherein the melting point of said soldering metal material is lower than that of said second component.

3. The golf club head joining method as claimed in claim 1, wherein said first component is a low-melting-point metal and said second component is a high-melting-point metal, wherein the melting point of said soldering metal material is lower than that of said first component.

4. The golf club head joining method as claimed in claim 1, wherein said first component and said second component are heated by a laser, a gas flame gun or an infrared heat gun.

5. The golf club head joining method as claimed in claim 1, wherein said first component and said second component are heated in a gas furnace or a continuous furnace by inert gas injection.

6. The golf club head joining method as claimed in claim 5, wherein said inert gas is selected from the group consisting of nitrogen, argon and helium.

7. The golf club head joining method as claimed in claim 1, wherein said first component and said second component are heated in a vacuum furnace under vacuum conditions.

8. The golf club head joining method as claimed in claim 1, wherein said first component is a main body and said second component is a golf club head top or a ball striking surface.

9. The golf club head joining method as claimed in claim 1, wherein said first component is a golf club head top or a ball striking surface and said second component is a main body.

10. The golf club head joining method as claimed in claim 1, wherein said first component and said second component respectively are a frame body and a frame border.

11. The golf club head joining method as claimed in claim 1, wherein said first component and said second component respectively are a frame border and a frame body.

12. The golf club head joining method as claimed in claim 1, wherein said active metal is selected from the group consisting of nickel, silver, copper and gold.

13. The golf club head joining method as claimed in claim 1, wherein said compounds are nickel nitride, nickel carbide or nickel oxide.

14. The golf club head joining method as claimed in claim 1, wherein said compounds are silver nitride, silver carbide or silver oxide.

15. The golf club head joining method as claimed in claim 1, wherein said compounds are copper nitride, copper carbide or copper oxide.

16. The golf club head joining method as claimed in claim 1, wherein said compounds are gold nitride, gold carbide or gold oxide.

17. The golf club head joining method as claimed in claim 1, wherein said soldering metal material is selected from the group consisting of lead, zinc, indium, antimony and tin.

18. The golf club head joining method as claimed in claim 1, wherein said step of applying a coating of active metal or compounds suitable to be affixed with a soldering metal material on said first component and said second enables the surface thickness of said active metal or compound coating on said first component and said second component to be 0.5 μ

m to 50 μ

m.

19. The golf club head joining method as claimed in claim 1, wherein said step of applying a coating of active metal or compounds suitable to be affixed with a soldering metal material on said first component and said second component utilizes coating methods which are physical vapour deposition (PVD) method, chemical vapor deposition (CVD) method, electroplating method, electroless plating method or thermal spray method.

20. The golf club head joining method as claimed in claim 1, wherein said soldering metal material is a solid-state soldering sheet, a soldering rod or a semi-liquid solder paste.
