Discovery channel had a special on that new stadium in Arizona, and they showed that being done on the rails for the field.
Very neat.
I've done something similar with grounding. Copper wire is placed in a mold with a piece of rebar. A 'cupcake' is inserted in the top of the mold and ignited. A copper slug in the 'cupcake' melts and fuses the copper wire to the rebar.
