This is to increase the freedom of head weight distribution and center of gravity design by combining materials with specific gravity differences,
Alternatively, there are various effects such as changing the material only for the hitting surface to improve the feeling at the time of hitting.

It has been known that a sole plate b having a specific gravity larger than the specific gravity is fixed to the bottom surface of the head main body portion a via screws c, c screwed into the boss portions g, g. In an iron-type golf club head as shown in FIG. 10, a face-surface forming plate d made of a metal having a low specific gravity is fitted and press-fitted into a press-fitting stepped portion e of a head body f. It was known.

That is, in the case of the screwing shown in FIG. 9, the screw head is exposed, which is not preferable in appearance, and it is necessary to provide a boss g for screwing in the head main body a. Had become. Also, FIG.
In the case of the press-fitting shown in (1), basically, the cradle must be made with high accuracy, and it was very difficult to form a complicated shape. Further, since a large internal stress is generated by the press-fitting, there is a restriction on a practicable portion. Moreover, it was difficult to implement the method for a material having low strength. In addition, in the bonding with an adhesive, the strength is basically insufficient particularly at a portion where stress is relatively concentrated. Also, in the case of cast-in, it was necessary to be a material that could withstand the casting temperature, there were problems such as shrinkage due to high temperature, deformation, etc. .

The sub member 2 can be firmly fixed to the main member 1. In particular, compared to screwing or bonding with an adhesive, it can be firmly fixed and has high strength. Further, since there is no step between the main member 1, the sub member 2 and the weld metal 3, the outer surface of the head can be finished smoothly and the appearance becomes beautiful. Furthermore, as compared with the case of press-fitting, no cradle is required and the internal concave force is extremely small,
The main member 1 can be easily joined to a portion having a complicated shape or a portion having a low strength, and the strength can be increased.

ので、設計上の制約が少なく設計自由度が高くなった。In the first embodiment, the main metal member (head body) is manufactured by aluminum casting, the brass is used for the sub member (sole), and the welding metal is aluminum. Conventionally, the only way to join metals that can not be welded like aluminum and brass is to screw, glue, or press fit into a very limited part of the sole,
In contrast to the low degree of freedom in design, according to the first embodiment, the sub-member (brass) can be firmly fixed to almost the entire surface of the sole, and there is no need to back up the metal main member. The degree of freedom has been significantly improved. Further, since no stepped portion is formed on the main member as compared with the second, third, fourth, and fifth embodiments, design restrictions are reduced and design freedom is increased.

が容易であった。In the second embodiment, the main member is made of 6-4 titanium, the sub member is made of brass, and the welding metal is made of pure titanium. According to Example 2, the build-up of the weld metal could be reduced during manufacturing. In addition, it was easy to grind the raised portion of the weld metal so that the outer surfaces of the weld metal, the main member, and the sub member became continuous.

According to the third embodiment, during manufacturing, a recess is formed between the stepped portion of the main member and the outer edge of the sub-member, and welding is performed on the main member so that the weld metal flows into the recess. Since it is sufficient to perform the welding, the amount of the build-up due to welding could be further reduced. Further, smoothing of the weld metal after welding by grinding was easier.

Further, in the fifth embodiment, the main member is made of aluminum, the sub member is made of tungsten, and the weld metal is made of aluminum. According to the fourth and fifth embodiments, similarly to the third embodiment, it is possible to further reduce the amount of build-up by welding, and it is easier to smooth the weld metal after welding by grinding.

出するので外観上好ましくない。In Conventional Example 1, a brass sole plate is adhered to the bottom surface of an aluminum head main body with an adhesive and screwed, and a backup is required for the head main body sole portion. In addition, since it is necessary to provide a boss portion for the screw on the head body, there is a disadvantage that the degree of freedom in design is significantly restricted, and furthermore, the screw head is exposed on the sole surface, which is not preferable in appearance.
