Case No. 92117284 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a Gaul I seven-in-one method, in particular to a combination structure of the weight block of the head and the melting point of the material of the junction body and a solder, The weight block is welded to the golf club head in the cup head and the chamber: the weight block is inserted into the head body [prior art] The conventional golf club head has a better rebound coefficient [C0R] The material is proud of ^ / talk about the effect of clay, usually choose ^ λα ^ ^ 4 α is 5 Haierfu club head body,

As shown in the figure, the weight block 2 ^ is second to the head body 1. The weight block 2 is embedded in the / head body 1 by a tight fit. Valley to ii. Then, the surfaces of the head body 1 and the weight block 2 are surface-treated to complete the finished head body i. However, for the j weight block 2 series, a material with a high specific gravity is selected. This kind of material has the characteristics of being hard, relatively south, and easily broken. In the process of manufacturing the weight block 2, it is difficult to accurately cast and mold to match the club head. The outline of the volume u of the body 丨, because ^ when the weight 2 is pressed into the head body 1 after being pushed in, it is easy to cause the weighting .........

In addition, after the surface treatment, a gap is generated between the head body 1 = to 1 and the contour of the weight block 2, and the fitting shape 7 needs to be filled. h J The surface of the weight is tightly duplicated. Since the weight 2 that fills the gap between the chamber 11 and the weight 2 is disengaged from the two polymers, it is easy to cause the weight of the balance after a long-term impact. Z is released from the head body 1. As shown in Fig. 2, the weight block of another conventional golf club head, the block 4 [-as shown by the dashed line] is first accommodated in the chamber of the head body 3 ^ Capacity = Π Ϊ connection method The weight block 4 is welded into the head body 3 to 1. Although the head body 3 and the weight block 4 can be used to improve the bonding strength between the two, however, because the high temperature = ff head body 3 and the weight block 4 both generate melting, the molten pool disturbance during welding; Welding speed, current, heat input and other changes make the depth of the bead different, so the surface between the head body 3 and the weight block 4 after surface treatment, leaving two irregular knowledge of 32, resulting in golf clubs The quality of the head is not easy to touch and beautiful. Furthermore, if the head body 3 is made of titanium or titanium alloy, the weldability between titanium and dissimilar metals is not good, which often causes welding thermal cracking. Published, Titanium Fresh Welding Technology, p. '^ 4, Section 3.2, 2 Welding and joining of titanium and other metals: Titanium and dissimilar metals. In terms of this, it has been said that the appearance is similar, but titanium The sake, titanium and titanium will embrittle the weld. Titanium and dissimilar metals are fused and welded. They cannot belong to the same category in the periodic table of the element [Zirconium, Niobium, Nitalum Tantalum, Hafniuin]. In view of this, the present invention improves the above-mentioned disadvantages. It uses a material with a melting point having a melting point higher than the melting point of a club head body and a solder.

Ptc The convex part and a club head body are filled when they are melted; ^ Disengaged 'enables the present invention to have a combined structure and a square head body and a piece of solder contained in the container. The chamber interior wall and the solder fusion weight block are welded and combined in V. Description of the Invention (3) ^ When one of the head bodies is contained in the container, the " Height weight block can be combined in the container to produce fusion. [Summary of the invention] The main purpose of the present invention is to provide a B structure and a bonding method, which utilizes the melting point of a talented body and a solder. When the body is in the second container, only the rod can be melted to combine the weight block with The smelting in the container makes the present invention have the effect of gaining high quality control. A secondary object of the present invention is to provide a combined structure and a combination method in which a channel is formed between a pair of valley chambers, and the channel γ can prevent the weight block from improving the quality of the golf club head. According to the golf club head method of the present invention, the materials of the weights have melting points, respectively. The head body is provided with a container chamber ^ When welding, only the weight of the rod and the weight block can be prevented from being melted in the container chamber. [Embodiment] In order to make the above and other aspects of the present invention easier to understand, hereinafter, it is preferred that the present invention only melts the head body and solder, that is, the weight of the weight block in a golf club head can be avoided. The material melting point of the weight block is higher than when the weight block is welded to the inner wall of the head body of the club head and the solder, so as to prevent the weight block from producing a beautiful club head and improving the process variety. One of the weights of the golf club head is a solder on the head body. The weight block is higher than one bar.

Description of the invention (6) The inner wall of the chamber 51 of the head body 5 and the unmelted state, and the weight block 6 of the head still maintains the head body 5 as shown by the dotted line]. a then forms a local fusion [as shown in Figure 6 please refer to Figures 7 and 8, when the material 7 is cooled and solidified, it is welded and welded in the part 5 of the head body 5 of Xitian ^ Rong. 5 and the counterweight broadcaster, the master and the master, the groove 迢 a between the solder 7 and the head body 546 is formed to form a -clamping section b. At this time, the inner wall is partially consolidated to form the same material, so the head is made of the same material; the body 5 and the solder 7 are not thinned when they are welded. 7 The capacity block Λ is used for fixing the weight block 6 to the head body 5 After re-selecting fi t 矣 rffr Bu Guang and Wu Wucheng, the solder 7 is opened on the head body 5 and equipped with 矣 δδ 卢 Φ 'Into a convex body [as shown by the dotted line]. Finally, the surface is further treated, and the convex body is flattened, so that the head body 5 forms a flat surface. Because the weight block 6 and its protrusions are "not melted" when the solder 7 is melted, after the head body 5 is processed by the surface treatment process, there is no mutual fusion between the rod body 5 and the weight block 6, And still, the weight block 6 forms a clear outline on the surface of the head body 5, as shown in Fig. 8. In addition, the latching portion b is formed between the head body 5 and the weight block 6. The tightly-contacted and seamless joint surface is not only for the weight block 6 to be tightly combined in the chamber 5 1 of the head body 5, but also to increase the clamping strength between the head body 5 and the weight block 6.
