Abstract

A golf club head includes a golf club head body and a weight member mounted in a recession of the golf club head body. The weight member includes at least one solder channel for receiving solderable filler. The weight member is mounted in the recession of the golf club head body before a brazing process for bonding the weight member with the golf club head body. During the brazing process, the solderable filler is melted and fills a gap between the weight member and walls delimiting the recession of the golf club head body to thereby increasing bonding strength between the weight member and the walls delimiting the recession of the golf club head body.

Claims

1. A golf club head comprising:

a golf club head body including a recession; and

a weight member mounted in the recession of the golf club head body, the weight member comprising at least one solder channel for receiving solderable filler, the weight member being mounted in the recession of the golf club head body before a brazing process for bonding the weight member with the golf club head body, the solderable filler being melted and filling a gap between the weight member and a plurality of walls delimiting the recession of the golf club head body during the brazing process to thereby increasing bonding strength between the weight member and the walls of the recession of the golf club head body.

2. The golf club head as claimed in claim 1, wherein said weight member consists of plurality of engaging sides, said solder channel is provided on one of said engaging sides.

3. The golf club head as claimed in claim 1, wherein said at least one solder channel has a depth ranging between 0.03 mm and 0.2 mm.

4. The golf club head as claimed in claim 2, wherein said weight member includes a top engaging face, said at least one solder channel extending from one of the engaging sides to the top engaging face of the weight member, thereby allowing the molten solderable filler to flow to the engaging face of the weight member.

5. The golf club bead as claimed in claim 2, wherein said weight member includes at least one extension channel defined on one of the engaging sides to communicate with said at least one solder channel, and said at least one extension channel extending in a direction transverse to said at least one solder channel of the weight member.

6. The golf club head as claimed in claim 2, wherein said weight member includes at least one annular channel extending on the engaging sides of the weight member.

7. The golf club head as claimed in claim 1, wherein the recession of the golf club head body being delimited by a bottom wall and a plurality of side walls, the bottom wall including a plurality of positioning holes, the weight member including a plurality of positioning pegs respectively received in the positioning holes in a manner, that the bottom wall delimiting the recession of die golf club head body is spaced from the weight member.

8. The golf club head as claimed in claim 1, wherein the solderable filer is solid material.

9. The golf club head us claimed in claim 1, wherein an overall volume of said at least one solder channel of the weight member is not less than that of the gap between the weight member and the walls delimiting the recession of the golf club head body.

10. The golf club head as claimed in claim 1, wherein the solderable filler is a solder paste material.

11. The golf club head as claimed in claim 1, wherein an overall volume of said at least one solder channel of the weight member is twice as large as that of the gap between the weight member and the walls delimiting the recession of the golf club head body.

12. The golf club head as claimed in claim 1, wherein the golf club bead body is an iron club.

13. The golf club head as claimed in claim 1, wherein the golf club head body is a wood club.
