These other comments got me laughing. Yes we braze for medical gas lines in america. And hydronic systems lol. The lines need to be brazed in a medical gas system because the melting temperature is higher.
Why use so much heat when you can sweat just fine with a MAPP torch and have far less risk of overheating the copper? You have bluing several inches away from your solder joint, that isn't necessary and is weakening the walls of the pipe.
@@VikingPipefitter But you're also adding huge amounts of heat to your copper, which you do not want to melt, and the colour changing is evidence that the tempering (heat treating) of the copper has been ruined. That's going to fatigue and fail over time, not at the joint but on the pipe itself.

This is brazing not soldering it takes three times as much heat to melt brazing rod as soft solder

He was using type K copper lmao relax
Brazed copper joints are stronger, but yes the copper does anneal. Typically used in industrial and refrigeration applications.@@bloodleader5
Water doesnt smoke...
I didn’t think you Americans brazed? I thought you only soldered.
We do both depends on application
