US Patent 7086964 Weight member for a golf club head

A golf club head includes a golf club head body and a weight member mounted in a recession of the golf club head body. The weight member includes at least one compartment for receiving a filling material. The weight member is mounted in the recession of the golf club head body before a brazing process for bonding the weight member with the golf club head body. During the brazing process, the filling material is melted and fills a gap between the weight member and walls delimiting the recession of the golf club head body to thereby increasing bonding strength between the weight member and the walls delimiting the recession of the golf club head body.
