Silver solder is not as strong as brass (brazing). Brass is not as strong as welding. Committed to brazing since that it how it was originally constructed. The steel tubing is "contaminated" with brass. The photos of the needed repair show this is a top tube to seat post tube connection. Very structural area of the frame and it's a tandem also! Silver solder is more for trim or more detailed work and is not designed for this amount of stress. This repair demands as much strength as possible!
