ABSTRACT:
A golf club head includes two metal parts which are connected each other by welding their opposite surfaces. A method of making the golf club head constitutes: making the two metal parts, wherein at least one of them is provided with a small protrusion along the surface to be welded; and laser welding the opposite surfaces by applying a laser beam to at least the protrusion so that the molten material of the protrusion penetrates into a gap between the opposite surfaces to connect the two metal parts.
