    • A head body of a golf club head has a hollow portion defined by an outer wall. An opening portion is provided in a part of the head body. A small tungsten alloy piece having a shape fittable to the opening portion so as to cover the opening portion is fixedly attached to the opening portion by welding. The golf club head defines the opening portion in a part of the metal head body and has the small tungsten alloy piece fitted and joined to the opening portion by welding so that the golf club head can be reduced in weight because of provision of the hollow portion. Since the small tungsten alloy piece is joined to the opening portion by welding, difficult plastic forming is not required particularly, and the weight can be adjusted easily and accurately.
    • 高尔夫球杆头的头部具有由外壁限定的中空部分。 开口部分设置在头部本体的一部分中。 通过焊接将具有与开口部可配合以覆盖开口部的形状的小的钨合金件固定地安装在开口部。 高尔夫球杆头在金属头主体的一部分中限定开口部分,并且通过焊接将小的钨合金片装配并接合到开口部分,从而可以通过设置中空部分来减轻高尔夫球杆头的重量 。 由于小的钨合金片通过焊接与开口部接合,因此不需要特别的塑性成形,能够容易而准确地调整重量。
