The solder will not melt, mush less flow, before the gold to be
joined. I can literally put the flame on the solder (which beads
up) until the gold beneath it melts, but the solder doesn't.
Dale, Assuming you do not have faulty solder, what you describe is
totally logical, based on my own experience: If you direct the flame
on the solder, it will heat up, bead up and not flow. And often, by
the time the metal beneath reaches the flow temperature, the flux
has been burned off, preventing the solder from flowing at all. So
you add more heat thinking this is the problem. Eventually the gold
melts and you have a nice little mess to deal with. Been there, Done
Here’s the scoop on solder. For solder to flow, you need only a two
Clean, fluxed metal
Heat to attract the flowing solder
The key is that solder flows onto metal that is hotter than it is.
The gold beneath has to be heated, not the solder. When it reaches
the flow point of the solder, the solder will flow onto it.
Try heating the work, not the solder.
