Abstract: Disclosed is a golf club head including a faceplate portion and a main body constituting a remaining part of the golf club head. A plurality of linear protrusions formed parallel to one another on the rear surface (opposing to the front striking surface) of the faceplate portion. The linear protrusions have different lengths and are arranged in an elliptical pattern or a diamond pattern covering the vertical projection of the center-of-gravity of the golf club head on the rear surface of the faceplate portion.

Abstract: A golf club head includes a face portion disposed on a front face of a golf club head for hitting a golf ball and a sole portion formed on a lower portion of the golf club head. The sole portion includes a recessed deformation portion. The deformation portion includes a deformation-starting section, a deformation-ending section, and a maximum deformation section between the deformation-starting section and the deformation-ending section. A thickness of the deformation-starting section and a thickness of the deformation-ending section decrease toward the maximum deformation section so that the maximum deformation section has the smallest thickness allowing elastic deformation, thereby increasing elastic deforming capability of the sole portion.

Abstract: A putter head includes a body and a light insert. The body includes a face portion, two mass portions, and a connecting portion. The face portion is located on a front side of the body, the mass portions are located on two sides of the body, and the connecting portion is formed between the mass portions for connecting the mass portions, with a compartment being defined between the mass portion and the connecting portion. The light insert is securely mounted in the compartment of the body. The light insert includes at least one aiming mark on a top face thereof. Further, the club head has a center of gravity positioned within the light insert.

Abstract: A welding method for a golf club head includes preparing a first club head part made of Fe—Mn—Al alloy, preparing a second club head part made of an alloy having a melting point higher than that of the Fe—Mn—Al alloy, and bonding the first club head part and the second club head part together by high energy welding having an energy density substantially greater than 106 W/mm2, thereby causing momentary synchronous melting and secure welding bonding of the first club head part and the second club head part.
