I’m too lazy to look it up but there’s an arbitrary point, about 500C I think, that delineates soldering & brazing.
?
Otherwise as said it’s just melting a filler material into the joint.? Where the heat comes from doesn’t matter, I’ve used a torch on electronics (some things really need a lot of heat that most soldering irons just can’t deliver).
And honestly the only difference between ‘brazing’ and ’soldering’…is the temperature.?

Both are the same process: joining metal by melting a metal of a lower melting point to ‘wet’ the metal to be joined with the aid of a flux.

Cleanliness, flux, heat.?

Actually, that old plumber's "3 basic rules" apply just as well to brazing as to soft soldering. You're just using different flux and (a lot) more heat.

You do not want to "solder" a steam boiler! You need to braze it.

I do have to admit I have soldered a steam coil which was not directly fired.

?1. Cleanliness is the key to success - surfaces to be soldered MUST be cleaned to bright, shiny metal.

?2. Flux is your friend - apply it to all surfaces before heating.
?
?3. Solder flows towards the heat source - that was before hot melt glue guns were common.? The basic idea was to apply heat to the area you want the solder to flow towards, not the outer surface.
