Soldering uses a lower melting point filler metal than brazing does.
Soldering brazing and welding are similar but differ in small ways.
Welding differs from soldering in that in welding the base metals are actually melted and fused together creating a very strong bond.
It takes you from tools supplies needed charts of metals cleaning flux safety to soldering with a demonstration exercise that you can do.
