Can I cut a in-used water supply copper pipe and make a joint through welding with new section of copper pipe.

If I understand your question you are asking if you can solder (not weld) a new section of copper tubing to an old section of copper tubing. The answer is yes, providing the old section can be properly shut off and drained. Just make sure you use a tubing cutter to avoid damaging the old section and use emery cloth or a wire brush to clean all of the oxidation off of the old tubing where you will be soldering.
I assume you know how to solder.

Any water in the pipe would make sweating a new fitting very difficult if not near impossible, since heat plays a very important role.
You really haven't provided alot of crucial information for an accurate answer...however to try and cover all the bases...
For a leak...the best route may be to buy a repair clamp that bolts over the pipe and has a rubber seal that compresses over any holes in the old pipe, if that is what you are doing.
If you are planning on attaching a new fitting to run a new line off the existing line, there are valves that can pierce the side of the copper, depending on its diameter and gauge.
But one must be wary when using a saddle valve, it can crush the copper if the pipe wall is too soft.
Also, these type of products can have a narrow opening for the water to pass through, which could effect anything attached to that fitting.
This is assuming you are not speaking about the main line coming into the structure, before the pressure regulator, but a secondary supply line. I don't know if they make a saddle valve for high pressure lines or not...
For smaller diameter copper pipes, most home improvement stores have them, for larger diameter pipes, you may need to look to a plumbing supply store that is geared towards supplying professional plumbers.

If you use the old bread in the pipes trick, make sure you remove all of the aerators from all the faucets and let water run through them for a bit before reinstalling them. Otherwise you will be cleaning all off those aerators. You can "solder" or "sweat" the copper pipes on if you want to replace a section of piping. As others have said, just make sure the water is turned off before attempting any cutting and make sure the pipes are absolutely dry around the repair area. Any water that gets picked up by the solder will leave you with a leak that you will have to repair once you turn the water back on and see it leaking around the repair area. And that's not fun, pulling it all back apart and starting all over again.

I am going to assume that by "in use" you mean not shut down and properly drained so you can solder. If that is the case you can but only after you shut the water supply off. You can cut the pipe shove some compacted bread up each of the pipes and the proceed to add a "T" or whatever extension you had in mind. After completion, you turn the water on and the bread will dissolve in the water and be gone. In the meantime you were able to solder an area that you other wise couldn't because of the water in the pipe. In case you don't know the water prevents the pipe from reaching the necessary temperatures to melt solder by locking the temperature to the water boiling limit (and no higher).

No. First of all it is never a good idea to cut an "in-use" line. You would need to turn off the water in the line before you make any attempts to install a new section. Second, you don't weld copper, it must be soldered.

Yes, the secret is cleaning and prepping the old pipe. Use copper flux cleaner acid for best results..you may use some emery cloth to get down to the original copper.

sure you can sweat on a new pipe. just make sure all is dry or the joint will not hold

yes of coarse! but this is called sweating. if you have not done this before you should consider compression fittings or tiger grips!
