Sandcloth the end being soldered. Squish the end with pliers so it is tight. Put flux on the end and solder. Easier to buy a copper cap and solder that on!
No, it will not affect them
It melts solder. Solder was originally a mix of lead and tin that was used to join copper to copper (pipes and wiring) It is in the shape of a pistol, but does not shoot anything.
Lead is toxic to humans (causes brain damage) thus when using a solder to join copper water pipes it is best not to use a solder containing lead as this will get into the water passing through the pipes and slowly poison the user of this water.
It is called Brazing rods or lead free solder
That cant be done because as long as there is water in them the temperature of the pipe wont go up enough to allow the solder to flow. you have to remove the water.
Solder. It is an alloy of lead and tin, with a (relatively) low melting point. It only works with Copper or lead pipes.
The term "sweating" in Plumbing refers to the process of joining and sealing copper pipes and fittings by heating the copper and applying solder after the pipes/joint fitting have been properly cleaned and flux applied.

SWT: This stands for "sweat", which is another term for "solder" (typically used to join copper pipes).
Sweating copper is a method of joining two pieces of copper, generally copper pipes. The surfaces to be joined are first cleaned, then heated generally with a gas torch, then a flux is applied (flux is a material to prevent oxidation of the copper when heated) then a film of solder is run onto the cleaned surfaces whilst hot. This solder is "wiped" off leaving a fine film of solder on the copper. This is generally referred to as priming. The two surfaces can now be soldered together to make a water tight joint. Sometime bronze is used instead of solder but the operation is similar.
PEX pipe crimp rings will work. Need proper tool to crimp new rings.
compresion fittings usually work well if u have any problems use some sealing tape If you are going to have the pipes in wall use solder, any copper exposed you can use compression.
