In one aspect, the present invention relates to a method of joining wax patterns for fabricating a golf club head. In one embodiment, the method has the step of providing a prefabricated first wax pattern and a prefabricated second wax pattern, embedding a joining portion of the second wax pattern into a recess portion of the first wax pattern, heating a flange formed on the recess portion to make the flange soften, and using a flattening tool to fold the flange over and into a chambered receiving portion on the second wax pattern such that the first wax pattern and second wax pattern are melted into a whole, joined surfaces of the first wax pattern and the second wax pattern are joined tightly with no gaps, and a single wax pattern if formed.
