I can. lol... Yes, it can be done. although sometimes difficult, if cause of leak is due to fitting or pipe not being clean then the answer is no, both need to be clean. if problem is lack of flux or moisture in line then answer is yes.
All the water must be out of the pipe before you try though.

How can you re-solder a joint in a copper pipe without removing it The water has been shut off and the joint is running vertically but when heat is applied more water sweats out?
You cannot sweat copper pipe if it has water in it. You must remove the water first. Even the steam from water will keep you from successfully sweating a joint without leaks. bob...
How do you stick copper to copper?
With fllux, solder and a torch. clean both surfaces with steel wool or sand paper, put a thin film of flux on each piece on the entire area that will be joined. Heat on one side and put the solder on the opposite side. When the copper get hot enough to melt the solder, the flame from the torch will draw the solder to it. That way you know there is solder in the whole joint.
What am I doing wrong when I can't get the solder to stick when soldering a copper pipe?
Not cleaning the pipe or joint enough, not using flux, or not heating the pipe or joint enough. You use the blue tip of the flame on the joint and the capillary action sucks the solder into the joint. You have to clean the pipe with sandpaper or steel wool, the joints with a fitting brush on the inside, and use a proper flux and solder.
What are the six types of bad solder connections?
Six types of bad solder connections include a cold joint with insufficient wetting (Pin) or insufficient wetting (Pad), a disturbed joint, an overheated joint, too much solder, or not enough solder.
What is flux used for when soldering?
Flux is used to keep metals from oxidizing. Solder will not bond well with copper-oxides which are formed when copper is exposed to high temperatures (ie a soldering iron) the flux prevents the oxidation. If you were to solder without flux the solder joint would be weak and possibly completely nonconductive.
What is sweated copper?
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.
What is a poor solder joint called?
A dry joint
Lead pipe connected to copper pipe?
Easiest way to connect lead to copper /brass is a wiped joint consisting 40 - 60 solder alloy as this gives a longer pasty range
What is a bad solder joint?
A soldered joint that was done poorly.
What is the plumbing term MEANS?
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.
You want to replace old lead pipe connected to cast iron sewer pipe with copper How do you connect the copper pipe to the old lead pipe or to the cast iron 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
