る。Recently, in order to stabilize the direction of the ball and obtain a longer flight distance when the ball is hit with a golf club, for example, in an iron head, a face member which is a part of the face of the head is made of aluminum. , Aluminum alloy, titanium, formed of a material having a relatively small specific gravity such as a titanium alloy, the head body member other than the face member, stainless steel, soft iron, copper, copper alloy,
Tungsten, brass or the like, which is formed of a material having a higher specific gravity than the face plate and integrated, or a weight member made of a material having a higher specific gravity than the material forming the head on a back member corresponding to the back surface of the face member of the head The attached ones are seen. In some wood heads, a sole member constituting the bottom surface of the head is formed of a material having a higher specific gravity than the other members, and both are joined and fixed.

いた。[0004] It is known that, by adopting the above configuration, the head can increase the moment of inertia around the center of gravity of the head and can adjust the position of the center of gravity to be deep. Therefore, the material forming the head body member and the face member, the material forming the sole member and the head body member, or the weight member attached to the head are made of different metal materials.

したものが公知である。In order to form a head by joining and fixing the members made of different kinds of metal materials to each other, each member is fixed with a connecting member such as a screw, and a concave and convex portion for fitting is formed in each member. , Press-fit into the uneven portion, fit together by caulking or the like, and integrate them, or bonding using an adhesive,
Or what is integrated by what is called fusion welding, such as arc welding, is known.

が損なわれるという欠点があった。The following problems have been encountered in the case where the members made of the dissimilar metal materials are joined and fixed to be integrated. That is, when the above members are joined using various joining members that are separate members, for example, in order to attach the face member to the head body member, the face member is inserted into the insertion recess in the face portion of the head body member. When both are fixed using a coupling member such as a screw, not only the number of parts and the number of steps are increased, but also the aesthetic appearance is impaired because the screw appears on the face surface of the completed head.

If the two are fitted by press-fitting or a caulked portion is formed on the periphery of the member, and the two are fitted and joined and fixed by caulking, the two are not necessarily in close contact with each other. There is a possibility that a gap may be formed between the two members due to a shock at the time or the face member may be peeled off.

外観が好ましくなかった。When members made of these dissimilar metal materials are joined by fusion welding, the members to be joined are melted and joined, so that the members to be joined are made of different materials. If it is, it is difficult to melt weld, it is difficult to obtain sufficient welding strength,
The appearance was unfavorable because the weld bead that appeared on the surface remained even after finishing polishing.

Should be formed. For example, when the face member 4 is made of an amorphous alloy material and the head body member 2 is made of pure titanium or a titanium alloy material, the wettability between the amorphous alloy material and the brazing member 7 is relatively good. Since there is room for improvement in wettability with the pure titanium or titanium alloy material that is the main body member 2, first, a metal material that has good adhesion to pure titanium or the titanium alloy material and has good wettability with the brazing member is used. By forming the metal surface treatment layer 7 on the surface of the head main body member 2 by using the above, the wettability between the metal surface treatment layer 6 and the brazing member 7 is good.
Inevitably, the face member 4 and the head body member 2 can be more securely and firmly joined.
