YOU thread or braze copper pipe Copper tubling you solder, braze, flaire, compression ring, mechincal joints
Take either an SOS pad or a wire brush and rough up both the inside of the brass fitting and outside of copper pipe, put the copper pipe into the fitting and solder around it.
tig or mig depending on the wall thicknessCopper to copper is either soft soldered, or silver solderedSilver solder is a bad term as "solder" normally means lead content according to the AWS
What to use to solder a shut off valve
Use a lead-free silver solder. It is the only thing that can handle the pressure and bond with the copper pipe.
Lots or reasons really. Copper does not rust, and its easier to repair if the pipe does happen to fail. Pex may be a more viable option if this is a DIY project due to cost of copper and skill required to solder connections. Depends on the applications such as waste, vent ,water supply. Copper Pipe is no longer used because of cost so many settle for copper tubing or Red Brass pipe 85% copper 15% zinc

It is probably referring to the type of fitting. A fitting that is soldered to a copper pipe. It is called sweating when you use solder and a torch to connect copper pipe together or attach fittings to copper pipe.
When I have to connect copper to lead "D" I usually solder the copper to the lead or wipe a lead joint depending on the diameter To connect copper to cast iron ,.... If there is a hub I caulk the copper directly into the CI with oakum and poured lead (molten) OR one can solder / braze a female adapter fitting and screw the copper into a CI female fitting
Wet on the surface is no problem, it will evaporate with the torch. If there is water in the pipe, it will not solder because the water keeps the copper from getting hot enough. As long as the water is below the point of solder, it will work. Open the nearest valve or have some way for the steam to get out of the pipe.
Yes, you can either solder them or fit mechanical (threaded) fittings.
Easiest way to connect lead to copper /brass is a wiped joint consisting 40 - 60 solder alloy as this gives a longer pasty range
