adhesion strength needed on a lugged frame?

Whats more important tensile strength or adhesion strength? JB Cold Weld has a tensile strength of 3900 PSI and an adhesion strength of 1800 PSI, is that strong enough to be used instead of brazing on a lugged steel road frame? thanks.

How you going to get it to flow into the joint ?

P.S., I think that brazing is more a chemical bond than an adhesive bond but then . . . what do I know about it? Not much.

No. Please do not try this. It would be extremely unsafe...if it even got out of the driveway.

Brass and silver have about 50-60ksi.

It's probably strong enough but not with the wild cut up lugs they make for typical road applications. A lot of bikes are/have been glued together. Old corbon frames, bamboo bikes. But you need a well socketed connection.
