I have a little leak on my ac line so I would like to know if there is any bonding agent that i can use to stop the leak, that would have prevented me from going trough the trouble of pulling so many things to get it weld.

My suggestion is to fix it correctly the first time.

If the line is accessible and not corroded you can try recovering the refrigerant and using aluminum braze to seal the line without removing it from the car. Be very careful though, make sure that it does no attach to a flexible rubber line close to where you are brazing or you will damage the rubber.

Whatever you do, don't use A/C "Sealers" in a Can, they are proven to cause problems.

Where is the leak? If there's some room around it, I'd cut it out, then use an Airsept splice. It is basically a glorified compression fitting, but made specifically for A/C use with seals that resist vibration and have some degree of accommodation for slightly out of round tubings. Aluminum brazing takes practice and given the number of parts in your car that can be heat damaged and fire hazard, I would opt for the splice. Use a tiny tubing cutter to cut out a ring section of damaged pipe.
