A golf club head is formed from two separate pieces. One of such pieces constitutes the face plate while the other piece constitutes the sole plate and the top crown of the club head. The pieces are welded together to form a hollow shell. The sole plate and the top crown are connected together with a hinge. These hinged pieces are joined in a closed position in a nest die and spot welded together. The face plate is then seam welded to the sole plate and the top crown in an argon chamber to form an integral unit.
