Method of sustaining metallic golf club head sole plate profile by confined brazing or welding

In the method of sustaining a metallic golf club head sole profile, the head having a bottom wall defining an opening with a peripheral and undercut ledge extending about said opening to support a sole plate received into said opening and on the ledge surface, the head defining a hollow shell, the steps that include

• (a) providing a dam on and integral with the head bottom wall and of the same metal as said wall extending about said opening and to project outwardly to substantially greater extent than the sole plate when the sole plate is supported on said ledge surface,
• (b) joining the sole plate to the head by producing a metallic melt in a peripheral space extending at and about the sole plate periphery with the melt in contact with the ledge surface and to a melt thickness at least as thick as the sole plate, and employing the dam to confine the melt at the side of the dam proximate the sole plate, and
• (c) thereafter removing the dam by abrading same to the common level of outer surfaces defined by the sole plate and head wall.
