Integrated structure of golf club head and striking face

Abstract

An integrated structure of golf club head and striking face includes a primary body and a secondary body formed by dividing a belly of a club head between one quarter and one third portion. The primary body has a head body and a striking face. The head body has a first tangent surface on one side with a wedging ridge formed thereon. The secondary body has a second tangent surface on one side engageable with the first tangent surface and a balance weight close to the second tangent surface. The second tangent surface has an annular groove corresponding to the wedging ridge so that the primary body and the secondary body can be welded together. The welding spot is moved outside the striking face. The welding amount is smaller. The gravity center of the club head can be moved rearwards at an optimal position.

1 . An integrated structure of golf club head and striking face comprising a primary body and a secondary body formed by dividing a golf club head between one quarter and one third of a belly portion thereof, wherein:
 the primary body includes a head body and a striking face, the head body having a first tangent surface on one side that has a wedging ridge formed thereon;   the second body includes a second tangent surface engageable with the first tangent surface that has an annular groove corresponding to the wedging ridge and a balance weight close to the second tangent surface, the primary body and the secondary body being coupled together by welding through the wedging ridge and the annular groove.   
   
   
       2 . The integrated structure of golf club head and striking face of  claim 1 , wherein the head body and the striking face are coupled integrally by forging. 
   
   
       3 . The integrated structure of golf club head and striking face of  claim 1 , wherein the head body and the striking face are coupled integrally by casting. 
   
   
       4 . The integrated structure of golf club head and striking face of  claim 1 , wherein the head body has an indented surface and a balance weight located thereon to shift the gravity center of the club head, the indented surface being covered by a sealing cap by bonding.
