The difference between thegolf head 4 of the third embodiment and thegolf head 3 of the second embodiment ofFIG. 3A merely lies in that thesecond bevel 421 does not have any bumps, which thus will not be described herein in detail. - Referring to
FIGS. 5A to 5B , they are schematic views of a method of welding a golf head according to the present invention. Only thegolf head 2 of the first embodiment ofFIG. 2A is set as an example for illustration herein. The welding method is also suitable for thegolf head 3 of the second embodiment ofFIG. 3A and thegolf head 4 of the third embodiment ofFIG. 4A . Referring toFIGS. 2A and 5A , firstly, thesecond welding surface 221 is disposed opposite to thefirst welding surface 212, such that themetal body 21 is pre-combined and fixed with themetal plate 22. Referring toFIG. 5B , then, afirst electrode 51 and asecond electrode 52 are used to contact aback surface 214 of themetal body 21 and atop surface 223 of themetal plate 22 respectively. Next, a current is conducted to thefirst electrode 51 and thesecond electrode 52, so as to weld thefirst welding surface 212 of themetal body 21 and thesecond welding surface 221 of themetal plate 22 by a resistance welding method. - The shapes of the
first electrode 51 and thesecond electrode 52 are particularly designed in order to match the shapes of theback surface 214 of themetal body 21 and thetop surface 223 of themetal plate 22 respectively, so as to control the pressure, voltage, and current applied on themetal body 21 and themetal plate 22 during the resistance welding process. Once the current is conducted, a contact interface between themetal body 21 and themetal plate 22 generates joule heats due to the interface resistance. The generated joule heats are used to melt thefirst welding surface 212 of themetal body 21 and thesecond welding surface 221 of themetal plate 22, and then, themetal body 21 and themetal plate 22 are welded and jointed by using the pair of electrodes to apply a pressure thereon. - The method of welding the golf head according to the present invention is achieved through the resistance welding method, only one welding action is required, and thus, the time required to weld one golf head (including the time required for the electrode to apply a pressure, the time for conducting a current, the time for welding, and for removing the electrodes) is extremely short. Therefore, the method of welding the golf head according to the present invention can truly relieve the problem of the conventional fusion welding technique (e.g., plasma welding or laser welding) that it must weld along the weld and thus causing an overlong welding time, and thus, the welding speed is greatly enhanced, and the production efficiency is greatly increased.
- In addition, in the method of welding the golf head according to the present invention, the resistance welding method is used to make the metal body and the metal plate be mutually melted and combined with each other, so as to eliminate the disadvantage of the conventional arc welding technique that porosity and thermal cracks are generated at welding positions. Furthermore, the method of welding the golf head according to the present invention requires a low heat input, the deformation of work pieces is also relatively low, and there are no protruded weld, so that the golf head achieves a high flatness, and thus, the cost of the subsequent shaping and processing is reduced.
- It should be noted that, in the above embodiments, the resistance welding method applied to the golf head is taken as an example for illustration, and actually, it is not limited to being applied for welding the golf head, but also can be applied for welding any two metal elements. Herein, the shapes of the first and second electrodes also match those of a back surface of the first metal element and a top surface of the second metal element respectively. Next, the first electrode and the second electrode are used to contact the back surface of the first metal element and the top surface of the second metal element respectively. Then, a current is conducted to the first electrode and the second electrode, and the metal elements are welded by the resistance welding method, so as to achieve the above efficacy in a similar way.
- While the embodiments of the present invention have been illustrated and described, various modifications and improvements can be made by those skilled in the art. The embodiments of the present invention are therefore described in an illustrative but not restrictive sense. It is intended that the present invention may not be limited to the particular forms as illustrated, and that all modifications that maintain the spirit and scope of the present invention are within the scope as defined in the appended claims.
