Problems solved by technology

For example, in shot peening, compressive stress remains near the surface of the workpiece to improve the fatigue strength, but the heat generated during welding increases the temperature of the workpiece, so the metal structure recrystallizes and the residual stress disappears.

Embodiment 1

[0029] figure 1 It is an embodiment of a club head based on the present invention, and is a perspective view of a wooden club head composed of a club head body 1 , a club face plate 2 and a cap member 3 before joining. The club head body 1 including the club face 4, the club top 5, the club sole 6, the club side 7 and the neck 8 has a large opening in the center of the club face 4 and the club top 5, and the opening 9 from the club face and the club top Through the opening 10 , the rod bottom 6 and the inner side of the rod side 7 can be seen. The face plate 2 is joined to the face opening 9 of the head body 1 by welding. The head body 1 can be formed by, for example, a titanium alloy investment casting method.

[0030] figure 2 Shown is a wooden club head in which a face plate 2 is joined by laser welding, electron beam welding, or tungsten inert gas arc welding (TLG) on the club face opening 9 of the club face 4 of the club head body 1 described above. The panel 2 is co...

Abstract

A method of manufacturing a golf club head without losing treatment effect by applying peening treatment to the face and the inner surfaces around the face of the wood or iron golf club head formed in hollow structure with a metal material. In the wood or iron golf head formed in the hollow structure, reforming treatment is applied to the face and, as required, to areas around the face by utilizing an opening formed in a head body of a metal material, and the opening is closed with a cover member by using a method with which the treatment effect is not lost. Thus, a golf club with high functional performance which could not be achieved before can be easily provided at low cost.

Description

technical field [0001] The present invention relates to a method of manufacturing a golf club head. technical background [0002] As we all know, in order to improve the strength and aesthetics of metal golf club heads (hereinafter referred to as "club heads"), various heat treatments and surface treatments (hereinafter referred to as "modification treatments") are generally carried out now, such as , Shot peening treatment is performed on the inner surface to leave compressive stress on the inner surface (for example, Patent Document 1), and carburizing treatment is performed (for example, Patent Document 2). [0003] Everyone also knows that the most common manufacturing method for metal club heads, especially those with a hollow structure, is to weld two or more parts together. Welding under different types of parts materials often results in different melting points. Insufficient bonding strength. [0004] In addition, a golf club head in which an opening is provided i...
