Eli5: What is the difference between soldering and welding?

Answer 1

Welding is a liquid to liquid bond, soldering and brazing is a liquid to solid bond.

Brazing is done above 840 degrees f, and soldering is done at lower Temps.

So welding involves melting the base material, and then also melting the filler material. There’s also autogenous welding which uses no filler, but it’s still liquid to liquid.

And Brazing and soldering only melts the filler material.
