A metal golf club head is formed by welding together a first one-piece component (20) and a substantially bowl-shaped second one-piece component (10). The first one-piece component (20) has a front striking plate portion (21), a top crown portion (22) which extends rearwardly from the front striking plate portion (21), and a hose-like neck portion (23). The second one-piece component (10) has a bottom sole portion (11) and a rear surrounding wall portion (12) which extends upwardly from the bottom sole portion (11). The bottom sole portion (11) and the rear surrounding wall portion (12) define a front opening to be covered by the front striking plate portion (21) and a front edge (15) to confine the front opening. The rear surrounding wall portion (12) has a top open end (16) to be covered by the top crown portion (22). The front striking plate portion (21) is welded to the front edge (15) of the bottom sole portion (11) and the rear surrounding wall portion (12). The top crown portion (22) is welded to the top open end (16) of the rear surrounding wall portion (12). The rear of the crown portion can be chamfered off and the crown can be securely held against ribs (13). The weld (100) is strong as a result. |
