- At present, the golf club head is mainly made by pressing and braze welding. Pressing is used to deform the golf club through extruding, which is only suitable for the iron golf club, and the structure formed by pressing is unvaried. Braze welding is used to bond the main body of golf club head and the hitting face with braze welding materials under high temperature, after the main body and the hitting face are manufactured with metals.

However, themain body 1 and the hittingface 2 of the present invention are formed with a engaging bonding face respectively, preferably a concave section and a protruded section which can be engaged with each other, thus themain body 1 and the hittingface 2 can be bond strongly. The engaging structure also plays a role in restriction, which can restrict the stress being pressed on the sticking layer that is vertical to the bonding surface so as to reduce the possibility of falling off.FIGS. 1 a-1 d shows the structure of four kinds of bonding surfaces, however, in addition to those structures, the bonding surfaces can also be of other structures. The structures as shown inFIGS. 1 a-1 d include the concave section and the protruded section that can be engaged with each other (the position of the concave section and the protruded section is changeable): the bonding surfaces of themain body 1 and the hittingface 2 as shown inFIG. 1 a is formed with a protruded section respectively that are relative to each other so as to form an L-shaped head, and the concave and the protruded section of the L-shaped heads are engaged with each other.
