[Prior art]
Conventionally, this type is as follows.
[0003]
In the golf club industry, high-energy welding has gradually been used as a method of welding a golf club head and a face plate from the conventional tungsten inert gas arc welding (TIG). For example, laser beam welding (LBW) or plasma arc welding (PAW) has been used. When a golf club head and a face plate are manufactured using a manufacturing process of high energy welding, the design of the golf club head and the face plate must be changed according to the welding characteristics.
[0004]
As shown in FIGS. 4 and 5, the conventional golf club head face plate welding structure using the manufacturing process of high energy welding mainly concentrates heat and heat in high energy welding (including LBW and PAW). The head main body 10 and the face plate 20 are welded by an appropriate combination of components by utilizing the property of high permeability. An opening 11 is provided on the front surface of the head body 10, a filler flange 12 is formed to extend outward from the periphery of the opening 11, and the face plate 20 is assembled to the opening 11 of the head body 10. A gap of only 1 mm is formed between the two. The filler 13 is formed by melting the filler flange 12 using high energy welding according to the above-described composition of the assembly, and the head body 10 and the face plate 20 can be joined by the filler 13. Has been.
[0005]
In addition, as a conventional golf club head face plate welding structure, the head body is fixed to a mold, and the joint portion of the main body and the combined body is machined using a processing machine to accurately size the joint portion. Finish the assembly, position the joint of the body to be joined to the body, set the laser beam marching trajectory during the first welding, and set it again between the body and the body. There is one in which the joint portion is welded and fixed by a laser welding method (see, for example, Patent Document 1).

[Problems to be solved by the invention]
In the conventional welding structure of the face plate of the golf club head, the head body 10 and the face plate 20 are applied to the manufacturing process of high energy welding, the width of the welding path is relatively small, and the welding depth is relatively small. It has advantages such as deepness and relatively good welding quality. However, since the gap (tolerance) between the head main body 10 and the face plate 20 is too small, the face plate 20 is used for the head assembly when both perform preliminary assembly (spot welding) and high energy welding. Since the surface tends to incline or shift outward from the front surface of the main body 10, such a situation should be corrected immediately after temporary welding, and if it does not improve, There has been a problem that the surface of the plate 20 is permanently shifted, and further, the overall non-defective rate of the finished product of the golf club head is lowered.
