Problems solved by technology

[0004] However, in the golf club described in the above-mentioned International Publication No. WO01 / 056666 pamphlet, there are problems such as uneven distribution of flow lines in the head surface, and variations in the strength and toughness of the head surface depending on the position.
In addition, this brings about the problem that it is difficult to obtain a good hitting feeling when hitting a ball with a conventional golf club.

Abstract

A golf club and munufactureing method thereof. The inventive golf club includes a golf head including a face portion with a ball hitting surface and a neck portion connecting the face portion to a shaft. Grain flows are formed in the golf head, and density of grain flows inside the golf head is made comparable to density of grain flows at a surface layer portion.

Description

technical field [0001] The present invention relates to a golf club and its manufacturing method, in particular to a golf club with integrally formed club head face and hosel neck and its manufacturing method. Background technique [0002] A head portion of a golf club includes a head face having a ball-striking face, and a hosel connecting the head face and a shaft. In the past, as a golf club head made by forging, the head surface and the hosel were integrally formed, but there was a problem that the hosel was easily deformed when the ball was hit, so it had to be thickened. hosel, it is difficult to reduce the mass distribution to the hosel. In addition, the head surface and the hosel are formed in separate processes, and then joined to each other. Therefore, there is a problem in that the strength of the joint portion between the head surface and the hosel is lowered. [0003] For such a problem, for example, a golf club described in International Publication No. WO01...
