ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a method for producing a golf club head, more particularly to a method for quickly producing a golf club head.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional method for producing a golf club head is shown to comprise the steps of preparing
11
, welding
12
and finishing
13
. In step
11
, a plurality of face plates
21
are prepared. The face plates
21
complement with one another to form a golf club head
2
, as best illustrated in FIG.
2
. In step
12
, the face plates
21
are welded manually and are joined by means of a solder stick to form the golf club head
2
. Finally, the golf club head
2
is finished by grinding an external surface thereof.
Such a conventional method suffers from the following disadvantages:
1. Because the face plates
21
are joined manually, the manufacturing speed of the golf club head
2
is relatively slow.
2. Since the material of the solder stick is usually the same as that of the golf club head
2
, the solder material that can be employed to weld a golf club head of a specific material is limited.
3. Since the solder and the golf club head are made of the same material of the same color, the appearance of the golf club head is monotonous.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a method for producing a golf club head that can overcome the disadvantages that are commonly associated with the aforementioned conventional method.
According to the present invention, the method for producing a golf club head comprises: preparing a plurality of face plates that complement with one another to form the golf club head; joining edges of the face plates to form a shape of the golf club head and providing grooves which extend between the adjoining edges of the face plates and which open at an outer surface of the golf club head; and welding the adjoining edges by placing the joined face plates in a mold and by introducing a solder into the mold for casting in the grooves.
