Description of the Invention: [Technical Field] The present invention relates to a golf club head and a welding method thereof, and more particularly to a golf club head using electric resistance welding and a welding method therefor. [Prior Art] Referring to Figs. 1A to 1C, there are shown schematic views of a welding method of a conventional golf club head. Referring to Fig. 1A, first, a metal body u is provided. The metal body 11 has an opening 1U having a ring groove 112. Referring to FIG. 1B, a striking panel 12 is provided. The striking panel 12 is shaped to fit the opening 111 and is disposed on the ring groove 12. Referring to FIG. 1C, finally, using a fusion welding technique (such as plasma welding or laser welding), in this embodiment, a laser light m emitted by a laser device 丨3 is used, along the metal body and The trajectory formed by the striking panel 12 is welded, so that a long welding time is required to cause a low welding speed. Therefore, the welding method of the conventional golf club head is inefficient. Furthermore, the metal body 11 and the striking panel 12 have a tolerance when combined, resulting in a large gap, or a deformation caused by a heat-affected zone in the soldering process, which easily causes a problem of poor quality of the Xue joint. Further, in the conventional method of welding a golf club head, there is also a method of welding a golf club head by means of arc welding. However, the arc welding method must also save the metal body and the outer trajectory welding of the striking panel, so that a longer welding time is required to cause a lower welding speed, and therefore, the production efficiency is poor. Furthermore, the arc welding technique causes pores and micro-grain at the weld to affect the joint strength of the golf head. i 11046-Amendment.doc 1307286 Whether it is laser welding or arc welding, a convex weld bead is formed between the metal body and the striking panel after the welding is completed, which requires time and labor for bead grinding After the operation, the production cost is increased. Therefore, it is necessary to provide an innovative and progressive golf club and its recording method to solve the above problems. SUMMARY OF THE INVENTION It is an object of the present invention to provide a golf club head. The golf head includes a metal body and a metal plate. The metal body has an opening having a first weld surface.

Therefore, the zinc bonding method of the golf ball of the present invention can greatly increase the speed of the material and greatly improve the production efficiency. In the welding method of the golf head of the present invention, the metal body and the metal plate phase (four) are fused by the resistor connection method to improve the defect that the soldering technique can cause pores and microcracks in the solder joint. . Furthermore, the welding method of the hairball head of Aiwuer, which has a low heat input, is low in the workpiece (four) and has no raised weld bead.

The metal plate 32 has a second inclined surface 321 opposite to the first inclined surface 312. The golf club head 3 of the second embodiment is different from the golf club head 2 of the first embodiment of FIG. 2A in that the opening 311 is provided with the first slope 312 (the first embodiment is opened) The first weld face 212 of the hole 211 is a right angle). In this embodiment, the second slope 321 has at least one second bump 322'. The second bump 322 is an annular flange as shown in Fig. 3C.

The golf head 4 includes a metal plate (four) and a 111046' Amendment.doc • 10.1307286 plate 42. The golf club head 4 of the third embodiment differs from the golf club head 3 of the first embodiment of FIG. 3 described above only in that the first slope 411 and the second slope 421 do not have any bumps. I will not go into details here. Referring to Figures 5A through 5B, there are shown schematic views of a method of welding a golf club head of the present invention. Here, only the golf club head 2 of the first embodiment of FIG. 2 is taken as an example. The welding method is also applicable to the golf club head 3 of the second embodiment of FIG. 3 a and FIG. The golf club head 4 of the third embodiment. Referring to FIG. 2A and FIG. 5A, first, the second soldering surface 221 is oppositely disposed on the first mating surface 212, and the metal body 21 and the metal plate 22 are pre-assembled and fixed. Referring to FIG. 5B, a first electrode 51 and a second electrode 52 respectively contact one of the back surface 214 of the metal body 21 and the top surface 223 of the metal plate 22. Then, a current is conducted to the first electrode 51 and the second electrode 52, and the first soldering surface 212 of the gold eyebrow body 21 and the second soldering surface of the metal plate 22 are joined by resistance fusion. The shapes of the first electrode 51 and the second electrode 52 are specifically designed to match the shape of the back surface 214 of the metal body 21 and the shape of the top surface 223 of the metal plate, so as to control the resistance when the resistor is freshly connected. The metal body takes the force of the metal plate 22 and the electric current. When the current is turned on, the interface between the metal body 21 and the metal plate 22 generates Joule heat due to the interface resistance. The metal body 21 and the metal plate 22 are fused, and the metal body 21 and the metal plate (4) are pressed by the pair of electrodes. The welding method of the golf ball head of the present invention is performed by a resistance welding method, and only needs - The second welding action can be completed, so it is necessary to pick up a new one. 111046-Amendment.doc 11 J307286 The time to the ball head (including the electrode field, energization, fresh connection and electrode removal time) is extremely short. The invention of the golf ball head fresh connection method can obviously improve the conventional welding technology (such as electro-convex welding or laser glazing) must be welded along the fresh road, causing the welding phase to be too long, so it can be greatly The welding speed is increased, and the production efficiency is greatly improved. In addition, the zinc bonding method of the golf ball head of the present invention can improve the conventional arc welding technology by melting and combining the metal body and the metal plate by a resistance fresh connection method. It will cause defects in the welds with pores and microcracks. In addition, the welding of the golf head of the present invention is low, and the amount of deformation of the work is low, and the weld bead of the coffee is so flat, so the state is flat. The cost of subsequent shaping and processing can be reduced. It should be noted that the above embodiment is only described by way of example of the electric resistance welding method of the golf ball head, but the electric resistance welding method is not limited to the welding of the golf head, and can also be applied. In the joining of any two metal components, the shapes of the first electrode and the second electrode used respectively match the shape of the back surface of the first metal component and the shape of the t-plane of the second metal component.
