  • Enjoyed watching this. In 1970 I commenced work as a refrigeration engineer and stayed in the industry for 14 years. Left and went on to other things. Have not brazed a joint since 1984! It hasn’t changed a bit in all that time. That was in the days before even mobile phones. Electronic instruments and controls were just being seen in the industry for the first time as I was leaving. From speaking to friends still in the industry and now at the end of their careers biggest changes seem to be the types of refrigerants (almost exclusively R12, 22 and 502 in those days), electronic and computerised controls and scroll compressors. Pleased I got out of the industry mind. Sometimes nostalgia kicks in but for the most part pleased with the choices I made. Thank you for the video.

I left the industry at 28 years of age and I was looking at men in their 50’s struggling to do the work. So I got out, studied at University and changed career to law. I am still working full time now and I am 67 entirely from home. Planning to retire next year but from choice, not because I can’t cope with the work. For me it was definitely a good choice to make. So I was coping no problem as a 28 year old but could see that would change as I got older.

  • I like your video, nice production. I just have a few notes. First, there was no mention of any nitrogen. Nitrogen is necessary to prevent the oxidation of the copper during the brazing process. The particles left behind, especially on very sensitive newer equipment can eventually lead to an obstruction like oil pooling in condenser coil or blocked TXV or piston. Second, prepping the copper correctly helps ensure a proper weld (add a bit more info for the beginners). Third, I liked the way you ensured a solid weld around the piping. I did notice that you had you stick bent allowing for about 1" of rod. Example, allow 2-4" of round off your coupling. Use the rule of thumb, if your nail can get caught on the joint, round it off more rod. Lastly, always heat the copper at the fitting not the pie going into fitting, this really helps. Especially with vertical braze joints. Good video, we all are learning each day!

  • The key to brazing in refrigeration is to get the joint hot quickly ( not red hot ) and fill it quickly. If you were to get a service valve, reversing valve, or TXV this hot, it would be ruined.

    • Agreed. There are a few options out there but I'm weary about some of them. The "cool gel" type products tend to work pretty well. I usually try to wrap a wet rag around the sensitive components. But brazing the suction line into an air handler is always a little scary for me because it's so close to everything else. Oxygen Acetylene works great to heat up quickly, but I rather use Acetylene. Just figuring out how to protect the components can get tricky.

  • Nicely made video dude, just a couple things to improve on in my opinion. Cherry red tends to be too hot for a quality joint, as you run the risk of porous braze joints. Preheat your female fitting to a dull red, and start to feed the brazing alloy in using the heat of the copper to melt the alloy. Flux is a must on dissimilar metal joints, and I suggest using 15% silver alloy for copper to copper. 45% for copper to brass etc. plus flux.

  • Good tutorial. I've been in HVACR many years and never used acetylene without oxygen so I can't opinion on whether is better but it appears that the pipe is a little bit hotter than it needs to be. Okay for pipe to pipe connections but maybe too long and too hot for heat sensitive connections like reversing valves, TXV's, service valves etc. even though a heat block paste or damp rag is implemented. I use 15% brazing rod and I find it flows much better than 5% at a lower heat. I did learn that I don't clean my copper as well as I should. Lol...

  • In the industry we use a Oxy/acetylene kit, the only place we use a B tank with turbo torch is on open lineset mostly in commercial refrigeration. Also use a silfos alloy and not some cheap silver. Don't heat the cupling first, always the pipe first so the silfos stick to the pipe then heat the fitting to penetrate. Flux is used when you use different metal and also when reusing old piping.

  • When cleaning the burr the copper line must be tilted down so the burr doesn't get inside the tube. The tiniest amount will become a restriction. When brazing you should purge with nitrogen otherwise the scale produced inside the tube will mix it today's refrigerant oils causing restriction and or attach the compressor winding's..It should also be mentioned to use minimum 5% silver upwards to 15% silver content solder when welding air conditioning and refrigeration copper ..

I saw the stamping on one or two that looked like “Sil-Fos” or similar. Used two maybe but while wrapping for storage, the others were not stamped or marked in any fashion. I am sure analysis would show no silver content. What did Ben Franklin day? Buyer beware? I’m sure I got shorted. So ask, take a photo of response and same after it arrives and set time/date code on photos as depending on size/amount/cost, they let you keep it and re-send new.

  • Good video, but if you cut that joint in half, you will find flakes of contaminants on it from exposure to the air - bad news for orifices. An inert gas in the pipe while brazing will prevent the contamination by shielding it from the air.

  • I'm learning to braze at my new job. They use oxy-acetylene. Is there a benefit to using only acetylene? Also, reading the comments, it seems there is much more to brazing than maybe even the guys at work know. We just build chiller units.

    @kennya5165@kennya51654 жыл бұрын
    • If you are in a shop environment oxy-acetylene is probably better. A turbo torch can efficiently braze up to around 2 inch copper with the right tip. The real advantage is if you are lugging everything to a roof, one tank is lighter than two tanks. If you need to heat quickly, like a reversing valve, oxy-acetylene is the way to go.

  • air-acetylene is common in hvac in the us because it means you only have to haul 1 tank up the ladder to the roof, but it's not great for everything. i used to service small appliances like air conditioners, refrigerators and dehumidifiers where the tubing is very small, the working clearances are very tight and many times the units are made of plastic that you can't easily shield from heat. in those cases a small oxyacetylene setup with small tips and special tips like the uniweld cap'n-hook work much better because you can braze the joint very quickly without setting things on fire or melting them.

    • They are called brazing rods. They come in different percentages and that percentage is the silver content in them. Higher the percentage, higher silver content and strength. Typically the standard is 5-15% for a solid connection from copper to copper. Make a clean cut, sand it down and braze👍 Thanks for watching!

  • One small critique if I may. If you hold the inner flame on the joint it will heat much more efficiently and move the flame in toward the fitting as the filler follows the heat. You don’t need so much on the pipe. Also, that long under the torch seems to weaken the fitting to a degree that it easily collapses at the slightest torque

    @scottkasper6378@scottkasper63784 жыл бұрын
    • The reason the fitting collapses is because heating it cherry red and allowing it to cool annuals the metal and makes it soft. If you heat it and then hit it with a cold rag quickly, it will harden again. This is tricky as a guy in the field probably isn't controlling the temperature that accurately and quenching improperly can create cracks and internal stresses.

    • Im not really an expert, but I agree. The heat draws the solder or braze in. Some of what happened here just layed more filler on yop, improving the look, but didn't likely travel in to where it counts. The idea is to work the torch to evenly heat the assembly and 123 add braze so it runs in. In some ways you only have one shot to really nail it perfect. Will still hold, but you'll have added twice the filler. Most will just be laying on top.
