BRIEF DESCRIPTION OF THE DRAWINGS The drawings illustrate one embodiment of the present invention.
This will be described below.

This embodiment is a method of manufacturing a hollow golf club head made of metal.

A substantially U-shaped welding member 7 is provided between the upper opening edge of the lower body 3 having the peripheral wall 2 on the bottom 1 and the opening edge of the upper body 4.
The welding member 7 is melted instead of a welding rod, and the upper edge of the peripheral wall 2 of the lower body 3 and the lower edge of the upper body 4 are joined.

[0014] The welding member 7 is specifically a plate-shaped welding member 7 in the transverse cross-section H-shape, the front and back surfaces widthwise center respectively upper member 4 of the lower edge, the upper edge of the peripheral wall 2 of the lower body 3 A concave groove 8 to be fitted is formed, and a lower edge of the upper body 4 and an upper edge of the peripheral wall 2 of the lower body 3 are fitted into the concave groove 8, respectively, so that the projecting portion 7a outward of the welding member 7 is melted. To form a head body 5 having an open front side. Due to the concave grooves 8, the upper body 8 and the lower body 3 can be temporarily fixed easily without rattling, and the welding operation can be performed smoothly.

The thickness and width of the welding member 7 are designed based on the amounts required for welding calculated in advance.

Then, a face plate 6 is welded to the front opening of the head body 5 prepared as described above, and then a neck portion 10 is attached according to a conventional method to manufacture a hollow golf club head made of metal.

Since the present embodiment has been described above, it is not necessary to consider how much the welding rod should be melted as in the conventional method, and the hollow golf club head can be manufactured more efficiently. You will get. The present embodiment also has the effect that the balance of the head can be arbitrarily set by appropriately designing the thickness and width of the welding member 7. By the way, according to this embodiment, the following features are also exhibited.

That is, by forming the protruding piece 11 as shown in FIGS. 5 and 6 at an appropriate position on the inner edge of the welding member 7, the balance (centroid position) of the head can be set to an arbitrary position. .

Further, as shown in FIG. 7, a welding member 7 having a projecting piece 9 formed on almost the entire inner edge as shown in FIG. 7 is provided, and the welding member 7 with the projecting piece 9 is mounted on a horizontal plane of the head as shown in FIG. And the height of the peripheral wall 2 of the lower body 3 is slightly lowered to set the position of the welding member 7 with the projecting piece 9 on the lower side so that the ball can be hit higher. A hollow golf club head can be manufactured. This means that the hollow golf club head is provided with a core material (a member that receives the impact force of the ball) at an angle corresponding to the launch angle of the ball, and the core material (projecting piece 9) is used to secure the ball. You will be able to launch higher.

Further, it has been confirmed that the direction of the ball is improved by the protruding pieces 9.

Therefore, by setting the angle of the welding member 7 with the projecting piece 9 with respect to the horizontal plane of the head arbitrarily, it is possible to arbitrarily set the launch angle of the ball and realize an accurate directionality. Become.

As described above, the present invention provides a method for manufacturing a golf club head which can be efficiently manufactured.
