How To Silver Solder (Braze) a Copper Pipe (A/C Line Repair) | GOT2LEARN

[@GenerationXT]

Years ago I switched to a double tip head for brazing tubing and never went back. It makes quick work of the job, helping to eliminate potential issues associated with having the flame on the joint too long, especially at compressor joints. The head is not very big and works nicely brazing in tight spots.

[@blacknigga119]

yes I use a double tipped head as well and it works so much better

[@fitter5426]

Not to bad my man. I’m typically pretty critical about people on UA-cam pointing out bad info people give on these type of informative videos because I’m a sprinkler fitter/pipefitter by trade. But this video pretty much covers it start to finish. Only thing you left out is that you can braze with a b-tank. You just need the bigger tip. We call them turbo torches. That’s what we use. But all in all man that was pretty damn good. Hats off.

surprised to see so many fitters applauding this video. Good info but the technique was pretty poor. The heat should be used to draw the filler around the joint as well as into it. The heat and dab moves are for welding not brazing... COME AT ME!

If you really need light equipment to solder you can use a map pro gas with two turbo torch, I used in 1/2 OD copper tube with %5 of silver, works good but the heat spread a lot and if you have some sensitive devices (sight glass, shut off valve or some pieces with seals) can be a problem, if this is your case practice with a wet raft before doing the final soldering.

We always adjust our torch so no black smoke comes out of it right at the beginning aswell and always close acetylene first so the oxygen can blow out the rest and you dont get black smoke.

For example while installing a new condenser on a split air conditioner. Can you explain this setup in a reply? Thanks.

Yes, they basically just you nitrogen to purge the lines while the braze, the pipe doesn't crust up as much inside and it prevent any regulators down the line from getting blocked

Nice video dude...I like the way you explain! Got a question for you...when the copper pipe is cherry red
and ready to melt the rod...are you saying to keep the flame torch on the copper pipe & not the rod
at that point..and to use the rod to melt around the copper pipe? I ask this as my brazing is a little
rusty and sometimes I'm not getting a smooth braze & not a good finish!
Also should the flame from the torch always be slightly above the solder rod when brazing
once the joint is ready to melt...such as a green flame?

[@Got2Learn]

I never heat the rod itself, the heat from the joint must melt it just like when soldering. I just heat the joint close to cherry red and follow the flame with the rod. Once that's done, I cap it ever so slightly to give it that extra strength :)

[@andyo9279]

@@Got2Learn Thanks for responding bro & your feedback but when you say you once it's cherry red and you follow the flame...what do you mean by that? I don't get you dude? Reason I'm saying that is the flame is already being heated over & covering the pipe! So how do you follow the flame?
Also what do you mean by you cap it ever so slightly regarding the joint?
Btw...I'm from London UK....Peace out y'all.. HVAC krew!

[@Got2Learn]

You need to make sure you are heating the pipe and applying the rod at the same time, so to do that, you need to heat offset of where you are applying your rod, for example: You heat at 12 o clock and you apply rod at 9 o clock while turning in a clockwise motion, the rod needs to follow the flame not the opposite, hope this is clear. This also makes sure that you aren't heating the actual rod, a mistake that a lot of people make!

The sulfur in the natural gas is whats bad for the copper lines. It will deteriorate it over time. Copper can be used for propane but I would only do that outside of the house for the high pressure side off the tank to the regulator like most company's do. Pretty sure they use type k copper.

one thing i never understood is how the rod starts melting so fast simply by scratching it on the surface,i mean dont it take time before the tip of the rod reaches its melting temp since the length of the rod acts like a heat sink ? or do the composition makes it retain heat much faster?

[@Got2Learn]

The surface becomes so hot it just has no choice to melt ;)

[@ARCSTREAMS]

@@Got2Learn seems like there is tremendous and fast heat transfer to the tip to be able to work so fast specially when its silver and cooper composition which by themselves need upwards of 1000degC to melt

@@Got2Learn on copper soldering or brazing would you say a neutral flame is better then carburising?

[@Got2Learn]

[@kenmore01]

I thought brazing was because you were using brass to weld with. I found that easier than welding but harder than soldering...but strong and could adhere to other things than the others. Live and learn!

[@Nate-pc9ox]

Braising is also used when connecting dissimilar metals, like brass to copper, stainless steel to copper etc. so you are not wrong. In HVAC/R we work with a bunch or brass, stainless steel and copper and have had to learn how to control the heat in such a way it doesn’t destroy those pieces or the components inside.

[@earthstewardude]

I have a small crack in the liquid line at the bend just above the compressor. tight spot, wondering if I should use 15% or higher and also a jewelers torch so I can avoid over heating / damaging the compressor? Did this happen because the 3 compressor anchor bolts were tightened down too much causing too much vibration on the liquid line.

[@urjnlegend]

It happened because who knows. The bolts are supposed to be tight, so the compressor won't vibrate so bad and so it stays put.
You want to use the normal brazing rod, only use a different type of rod, if you need the rod to braze different things (i.e. copper to steel, aluminium to copper, diff applications)
Idk what a Jewelers torch is, but as long as it gets hot enough to melt the brazing rod, that's what you need, as explained in the video. For simplicity sake, use a turbo torch or oxy acetylene torch.
Also, it sounds like you have no idea what you're doing, I hope you know what type of refrigerant is in the system, because if it's propane or something flammable, you're toast. The label isn't always correct. There might be some back pressure from the remaining refrigerant in the compressor, even after the refrigerant has been recovered, making it near impossible to braze.
Whenever you put the new line, give yourself wiggle room, so it doesn't crack again.
Hope it goes well, don't do it u less you know what you're doing, because you're going to have a bad time

[@earthstewardude]
