Description

  The present invention relates to a method of welding a head body and a face of a golf club head and a golf club head manufactured by the method.

  There is a conventional golf club head as shown in FIG. The golf club head is a flat body for striking a ball with a head body 10 having an opening 12 whose opening edge extends in the same plane and is in contact with the opening edge of the opening 12. The face 11 is welded to the head body 10 so as to completely shield the opening 12.

  More specifically, an annular protrusion 13 is formed at the opening edge of the head body 10, and an annular groove 14 is formed near the periphery of the face 11 as a striking face, so that the annular protrusion 13 is formed. The welding layer 15 is formed on the welding surface between the recording head main body 10 and the face 11 to bond them.

  The method of welding the head main body 10 and the face 11 of this golf club head is to install solder on the opening edge of the head main body 10 and then to form an annular shape between the annular protrusion 13 of the head main body 10 and the face 11. A so-called soldering is performed in which the concave groove 14 is fitted, the solder is sandwiched between the head main body 10 and the face 11, and the head main body 10 and the face 11 are heated to melt the solder. Is. In this method, since the solder is sandwiched between the annular protrusion 13 and the annular groove 14, when performing the soldering, the melted solder has a gap between the protrusion 13 and the groove 14. It protrudes from the head body 10 and the outer surface of the face 11. Therefore, it is necessary to grind the solder material adhering to the outer surface of the head body 10 or the face 11.

  FIG. 2 shows another golf club head. In the method of welding the head body 20 and the face 21 of this golf club head, first, a concave groove 22 is formed in the peripheral edge of the face 21, and the head body 20 and the face 21 are combined. After that, the portion of the head body 20 in contact with the face 21 is heated and melted, and the melted portion flows into a concave groove 22 formed in the face 20. In this method, the external appearance of the head main body 20 is deformed by the heating and melting, and it is necessary to correct the deformation by processing. In addition, since the head body 20 and the face 21 must be combined before heating the part of the head body 20 in contact with the face 21, the heated part of the head body 20 is the face 21. Therefore, there is a drawback that the head body 20 and the face 21 are uncertainly welded.

  FIG. 3 shows a golf club head manufactured by another welding method. In the method of welding the head body 30 and the face 31 of this golf club head, a solder material is installed in a concave groove 32 formed in the opening edge of the head body 30, and then the face 31 is attached to the head body 30. The solder is melted by heating after fitting the face 31 into the concave groove 32 while making contact with the opening edge. However, since the solder material is a powder, the volume of the solder material that has become liquid by heating becomes small and cannot fill the gap between the head body 30 and the face 31. There is a disadvantage that welding with the face 31 is unstable.

In view of the above, a main object of the present invention is to provide a method for welding a head body and a face of a golf club head that requires less processing and grinding and that can stably weld the head body and the face. There is.
