A golf club head formed by a combined "superplastic forming and diffusion bonding" method. The basic procedures are using three titanium sheets and machining shallow cavities into one of the sheets, which later provides the reinforcing function. Applying stop-off to the area where diffusion bonding is not desired and then sealing the three sheets by welding along their peripheries together with two gas supply tubes. The assembly then is placed into a die and a gas supply is attached. After vacuuming and heating up, the assembled part is subjected to subsequent diffusion bonding and superplastic inflation processes which yield a titanium golf club head with an internally strengthened striking face.
