ABSTRACT:
A golf club head comprises a main body and a striking plate. The main body is provided with an opening formed with a first stepped portion and a second stepped portion. The first stepped portion and the second stepped portion define a groove therebetween. The first stepped portion supports the striking plate with a reduced contact surface area so as to increase the effective elastically deforming area of the striking plate. Further, when the striking plate is combined with the main body by welding, the groove of the main body can obstruct an overflow of melting metal from a welding seam between the main body and the striking plate. Thereby the groove of the main body enhances welding quality and thereby overcomes the problems of club head noises and disturbance caused by flux beads and an inadequate coefficient of restitution caused by insufficient deforming area of the striking plate.
