Conventionally, there is a golf club head having a part where the metallic members are welded together, in which a face, a crown, a sole, and a hosel are welded by TIG welding, MIG welding, laser welding or electron beam welding (refer to 15 JP-A-5-15620) .
However, when the metallic members were welded together by TIG welding or MIG welding, there was a problem that the weight control for the golf club head was difficult because a welding rod was employed and there was a sink in the weld 20 zone.
Moreover, when the metallic members were welded together by laser welding or electron beam welding, there was a problem that the cost required for machining the metallic members was increased, because it was necessary to machine in advance the 25 metallic members precisely so as not to cause a gap between
1
the metal materials at the time of welding, although the weight control for the golf club head was easy because it was unnecessary to employ the welding rod and there was no sink in the weld zone. Especially when the metallic members with different 5 thickness were welded by laser welding or electron beam welding, the above-mentioned machining was difficult, and the cost required for machining the metallic members was very high.
SUMMARY OF THE INVENTION 10 The invention provides a golf club head having a part where the metallic members with different thickness are welded by plasma welding, laser welding or electron beam welding, in which it is unnecessary to machine in advance the metallic members precisely so as not to cause a gap between the metallic 15 members at the time of welding, and its manufacturing method.
According to an aspect of the present invention, a golf club head includes a first metallic member, a second metallic member having different thickness from the first metallic member, and a part where the first and second metallic members are welded 20 by plasma welding, laser welding or electron beam welding. A gap between the first and second metallic members is filled up with another metal material besides the first and second metallic members.

DETAILED DESCRIPTION OF THE INVENTION As the plasma welding of the invention, the well-known plasma welding may be employed in which the members to be welded are dissolved and resolidified due to high temperature energy 5 caused by plasma arc. As the laser welding, the well-known laser welding may be employed in which a gas laser such as CO laser or C02 laser, or a solid laser such as YAG laser is used. Also, as the electron beam welding, the well-known electron beam welding may be employed in which the electron beam of 10 appropriate output is used.
In the invention, the method of performing the plasma welding, laser welding or electron beam welding while filling up a gap between the metallic members with another metal material is not limited, but maybe implemented as the method of performing 15 the plasma welding, laser welding or electron beam welding, using a wire rod of another metal material, while filling up a gap between the metallic members with metal forming the wire rod. In this case, the wire rod of another metal material may suitably have a diameter from 0 .5 to 3.5mm, particularly from 20 1.0 to 2.5mm. Also, when the plasma welding is employed, it is preferred that another metal material is added between the joined members to provide a weld overlay at the juncture, because the weldability and the welding strength are increased even if the dimensional precision between the welded members is bad. 25 In the invention, a difference in thickness between the
4
metallic members to be welded is appropriately from 0 .1 to 1. 5mm, particularly from 0.2 to 0.6mm.
In the invention, the metallic members with different thickness may be selected from among titanium, titanium alloy, 5 aluminum and stainless steel. Also, another metal material for filling up a gap between the metallic members with different thickness may be selected from among titanium, titanium alloy, aluminum and stainless steel. Another metal material for filling up a gap between the metallic members with different thickness 10 is essentially the metal material separate from the metallic members with different thickness, and may or may not the same metal as one or both of the metallic members with different thickness.
Specifically, another metal material is preferably a 15 dissimilar metal that is equivalent at 60% or more of metal composition, particularly at 80% or more to one or both of the metallic members with different thickness . Also, anothermetal material may be suitably the metal material similar to the metallic members with different thickness, or its alloy, with 20 a difference in the melting point being from 0 to 200°C, particularly from 0 to 150°C.
The metallic members with different thickness and another metal material may be selected from among the metals having the following compositions (1) to (8) , but are not limited to 25 them. Among others, the combinations of (1) and (4) , (2) and
5
(4), (3) and (4), and (8) and (8) are particularly preferable.
