I've never used it or tried it, but google says you can use Silicon Bronze MIG wire. I've always just soldered stuff together but hey, I'm interested to see how it works. 2# spools of the stuff are only $30 so that might have to be a project for another day.

You must have an old Torch or it is the small one, MAPP may require changing jets.

I find that very hard to believe. If by some chance regular solder won't hold then silver solder would work for sure. Any form of mig welding is just ridiculous. If you don't trust either regular solder or silver solder then you might try tig welding with silicon bronze rod but it's still the wrong process...

If you are doing a sleeve connection any acceptable solder will be stronger than the parent pipe. if it is a butt joint good luck.
If vibration is an issue a decoupling section of suitable hose is the key.

According to the net, silver solder is over 70,000psi strength and melts at 1,145 °F.

Silver solder is a generic term like big mac.
Silver solder should be called silver bearing solder.
The exact metallurgical composition determines all of the characteristics of the sample such as melting temp , wetting characteristics and the correct metals to use it on.
It is very much like welding rod most will make a weldment but best results come from using the correct rod for the job.

You can't doo every job with a hammer & duck tape.

Sometimes it's best to farm it out.

Clearly this is such a case.

Most HVAC guys are using the silicon bronze with a turbo torch . On Heat Pump systems . At least around here .
