Driving panel welding method for golf pole head

Abstract

The present invention is the welded structure and method for the stroking panel of golf club head. The welding process includes the following steps: setting friction welding slant in the stroking panel and setting one corresponding friction welding slant inside the opening of the golf club head; combining these two friction welding slants; applying one force onto the stroking panel to make the stroking panel embedded closely into the opening; completing friction welding in the contact surfaces of the stroking panel and the golf club head body with one rotating unit; and completing the surface processing of the welded part to finish the golf club head.

Description

technical field [0001] The present invention relates to a welding method of a golf club head striking face plate, in particular to a method of setting a friction welding slope on a striking face plate and correspondingly setting another friction welding slope on a club head body so as to increase the reliability of friction welding. Background technique [0002] Nowadays, the design of golf club heads tends to form composite materials, especially the club head body and striking panel are usually made of different metal materials, for example, the club head body is made of 17-4PH stainless steel and the strike is made of 6 aluminum-4 vanadium titanium alloy. The panel, so that the golf club head can have both a high structural strength club head body and a high elastic deformation ability hitting panel. [0003] Although the design of the above-mentioned composite material can improve the hitting performance of the golf club head, it is relatively difficult to form a good joi...

Problems solved by technology

[0005] Although the friction welding method of the golf club head can simplify the manufacturing process and improve the bonding quality compared with the above-mentioned other bonding methods, the friction welding method still has the following problems: since the hitting panel 20 must rotate relative to the club head body 10, the hitting Panel 20 can only form a perfect circular shape, which cannot be used in conjunction with a non-circular strike panel 20; in addition, this strike panel 20 can only form a small hitting area, that is, its sweet spot (sweet spot) range is relatively large. Furthermore, if the contact area of ​​the friction abutment surface of the hitting panel 20 and the club head body 10 is too large or its surface has an oxide layer, it often results in the inability to effectively increase the friction temperature, so that when the friction welding is combined by An intermetallic layer (or hardened layer) is produced between the two

In particular, when the welding compatibility of the metal material of the hitting face plate 20 and the club head body 10 is insufficient, the characteristics of the intermetallic layer will not be conducive to improving the bonding strength, and will easily cause structural fragmentation or reduce elastic deformation capacity.

Based on the above-mentioned shortcomings, the size of the strike panel 20 is often unable to expand and is limited
