I could use some help with some of the terminology used in HVAC. I read some of these posts, and everybody has their own way of saying something.
For example, making a connection with silver solder
One definition of silver solder, is using a brazing alloy with 45% or higher silver. Melting range is around 1200* to 1400*.
Another definition of silver solder, is using a soft solder such as stay-brite, which has a silver content, but melts at 400-500*.
Which is the correct term?
I'd say its a general term for regular old 15 percent silver solder. Oops i mean brazing rod.....
Haha I think most people just say silver solder but are referring to " brazing" then again i have been known to say i had to " de-thaw the coil" and other hillbilly stuff all the time.
Personally, I always classified solder as soft material. IE: stay-brite, using propane or mapp to heat.
But that's just me.

Mechanical code states;
Solder has a melting point below 800degrees.
Braze has a melting point between 800 degrees, and the plastic melting point of the material being joined.
Welding is done at the melting point of the material.
If I'm using silver Braze, I say silver Braze. Braze is Braze, solder is solder, and silver bearing solder is silver solder.
