Are the joints brazed or soldered? What diameter is the tubing? When you say copper are you asking type K, L ,M , DWV , M or TP
If the hole is very small the material you are brazing with should fill it. A small piece sheet metal can be brazed in place to cover larger holes.
arc welding such as SMAW (stick), GMAW (mig). Some cast metals may be brazed for certain applications. The actual properties of the Cast metal will be needed for the type of electrode and/or process.
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
It is used to clean impurities away from the surface to be soldered or brazed. Many times it is included in the flux. The use of acid type of fluxes is actually detrimental to good plumbing , soldering practices because if the flux is not properly cleaned the joint will eat away from the corrosive action of the acid

Nope, it can be brazed, soldered, threaded
Yes
Welded, brazed or soldered.
You need a gunsmith. It might be possilbe or it might not be
Depends on how it is connected flare, compression or brazed or soldered or screwed IPS or FIPS
It depends on the manufacturer. Most futons I have seen are steel, and can be cut with a torch, brazed, and welded.
If it's a metal frame, then tubes are cut, mitered and stuck in a jig, then welded/brazed together. Headtube, bottom bracket shell are faced, reamed. BB shell threaded. For carbon fiber, the prepreg cloth is cut into shape, put into a mold, pressurized, heated and cured.
The actual magazine tube that connects to the receiver is brazed in there, so it removing it isn't an optimum solution.

No. This must be welded, bolted, screwed, brazed or otherwise fastened so that high temperatures and vibration will not cause it to fail.
