Titanium and gold inlay

I would like to know if any of you have had any experience with
titanium bands that have been inlayed with gold or platinum? I have
some 8mm bands that have been prepared in the mill to accomodate a
3mm strip of gold around them. I have seen several of these from
Fredrick Goldman using this metal combination, but am not sure as to
the process. Can any of you help me with this? Thanks!
