Abstract

A golf club head comprises a main body, and an assembling member. The main body has an assembling opening in which forms an inner welding circumference, a supporting edge, and a tapering portion. The assembling member has an outer welding circumference and a supported edge. In welding operation, the inner welding circumference of the main body connects with the outer welding circumference of the assembling member by welding while the supporting edge of the main body supporting the supported edge of the assembling member. Furthermore, the tapering portion provides with a relief space for releasing inert gas between the inner and outer welding circumference during welding operation so that improves the welding quality therebetween.

Description

1251500 V. Description of the Invention (1) [Technical Field of the Invention] The invention is constructed by a degree and a simultaneous construction. - [Previously used in the application of the Naner No. 5 1 8244 patent, ί, the striking trough has an integrated trough seat with a feeding saddle stomach shoulder, the edge I is deformed. The fusion joint is as above The method of using argon gas is as follows: ^:]. However, in addition to the retention between the plates of the panel, the welding will not be completely related to the welding joint structure of a golf club head, especially regarding the assembly of one of the heads of the club head, using a bottom edge of the building to increase the strength of the building. The diameter of the joint promotes the smooth release of the welding of the gas in the weld bead. The welding joint structure of the welder is referred to in the Republic of China. The invention includes the following steps: manufacturing a striking panel and a The head of the head has an outer edge, the head body is provided with a seat, the inner edge and a shoulder; the outer edge of the striker and the inner edge of the head are inclined outwardly, and the seat is The peripheral edge of the opening is embedded in the groove of the head body in the striking panel. 'The feeding protrusion of the head body is pressed by at least one pressing block. 'The welding is used to make the head body and the striking panel meet each other. The surface is ground for treatment.俨=When the main body and the striking panel are welded, regardless of the second, ^IG], laser welding, plasma welding or other welding, it is necessary to protect the welding position with an inert gas such as hydrogen (ie, welding north, right) When the shoulder of the seat of the head body is tightly abutted by two degrees, the seat and the striking face == gas. If the inert gas cannot be soldered at the right time, the "gas-entraining" defect is generated, which in turn causes the weld bead to greatly reduce the welding strength of the head body and the striking panel.

Furthermore, the back of the housing is tightly abutted, which is also relative to the margin of the panel. W filial piech inward elastic deformation Another common golf club head welding announcement No. 549 U2 "Golf: Raise 7, Qing Mai Zhao, Republic of China - the r which contains the complement: face: ί open, the opening There is no shoulder inside, but 'the circumference of the body forms a feeding flange, and the feeding flange is provided with a plastic mouth. The edge of the upper surface of the striking panel is fixed with several rods. C. The striking panel is embedded The inner edge of the opening and the striking panel are disposed at the opening, the hook of the material, and the flange of the material flange to support the front of the body and the striking panel before the welding process is completed. The outer edge of the outer edge is lacking (the scent is soaked at the right time, so that it can also avoid the occurrence of the body in the weld bead. However, the above-mentioned welded joint structure has the disadvantage that the support port causes the structure of the striking panel and the head body to be complicated. Chemical, no: i, fast pre-assembly. After welding, it also takes time to perform more than j2 =, kneading step: 丄 to remove the slab and the shackle. = 述 述 述 述 确 确 确 确It is necessary to further improve the above-described joint structure. In view of the above, the present invention improves the above-mentioned disadvantages, wherein one of the assembly ports is welded by a circumferential weld surface to the circumferential weld surface of a ball head group, and the support bottom edge is supported by a support bottom edge. The head of the ball, the outer edge of the shell, and the bottom edge of 70 pieces, C:\Logo-* Continents\PK9694.ptd page 7 1251500, invention description (3) and by a gas The invention relates to the invention, wherein the ball joint of the one-in-one ball head group is combined to release the inert gas, and the gas of the head element of the present invention is reliable. The diameter is k, a buffer space, in order to facilitate the release during welding, the present invention can relatively improve the welding quality, support reliability, and increase the elastic deformation margin. Although the purpose of providing a golf club head One assembly joint of the joint head body is provided with an inner circumferential welding surface and a one-week welding surface for welding and bonding a ball joint component. The diameter portion is provided with an appropriate number of support blocks to support the ball; To make the invention have The welding joint structure for improving the support strength and combining the reliable golf club head comprises a ball joint component. The club head body is provided with an assembly port, and has an inner peripheral joint surface, a support bottom edge and a reduced diameter portion. The word = one of the outer peripheral edge of one of the groups is provided, and the invention is provided with one body, wherein one of the head bodies is combined with one of the striking panels, and the outer peripheral welding is flexed inwardly. The utility model has the advantages of the margin of the margin. The invention is rebuilt, wherein the diameter of the component is the same as the degree of the combination of the components. According to the body of the present invention and the welding joint of the golf club head according to the assembly body The inner joint is welded to the welding surface by an inner circumferential welding surface, and a supporting bottom edge is used to provide a cushioning space by using a reduced diameter portion. The lifting joint quality is used to support the strength of the golf club head. The inner circumferential welding surface welds the knot surface and provides the hit by a reduced diameter portion, so that the invention has increased elastic deformation
