The other day iI had my airconditioningair conditioning repaired, and one thing iI saw the technician do is braze the copper pipes together. This got me thinking why dont idon't I see that done in electrical setting.

I understand that soldering is not good because it is brittle and a short circuit can melt those connection out of their joints. But brazing temps are so high that if it does melt something else more important have already melted before it. I mean i dontI don't think there are generic splicing kits (8 AWG or thinner) can handle brazing temps.

Taking it a step further, how about TIG welding? itIt basically melts the copper into a liquid state to join them for sure this makes a good connection, unpractical it may be. Just cover the welded part with heat shrink and voila ! a proper connection

Are there any electrical code (in your countries) that prohibits copper wire welding or brazing? I would see medium sizes wires can benifitbenefit from this (6-10 AWG maybe). Is it banned just because installers and technician cant do it propelyproperly consistently enough to be reliable?

Is brazing and TIG welding wires acceptable connection according to code?
