    摘要: The present invention provides a golf club head comprising: a face section made of a low specific gravity metal not higher than 5; and a back face section made of a clad material in which the low specific gravity metal and a high specific gravity metal not lower than 7 are metallurgically bonded to each other in advance, wherein the low specific gravity metal of the face section and the low specific gravity metal of the clad material are integrally joined to each other by welding so as to form a club head. In this case, the methods of welding of TIG, plasma arc and laser beams are used in which a U-shaped and/or V-shaped groove is formed. In this golf club head, it is possible to improve the mechanical strength of the joint portion, and it is also possible to produce the golf club head in a short period of time. Since the depth of the center of gravity is large and the center of gravity is lowered so that the moment of inertia can be enhanced, it is possible to provide a golf club head which can be easily swung by a golfer to get distance and a producing method therefor.
