HVAC Silver Soldering vs Brazing vs Brazing While Flowing Nitrogen!
Вставка
- Опубліковано 18 жов 2024
- In this HVAC Training Video, I Show Low Temperature Silver Soldering, High Temperature Brazing, and Brazing While Flowing Nitrogen. I Show What the Inside of the Tubing Looks Like and Discuss the Problems with Cupric Oxide and Flux! Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.

Another great video illustrating what takes place where you can’t see it.
Thank you for taking the time to do a job right.
You are my go to refrigeration Guru.
God bless such a great teacher, well explained. Your videos will give way more confidence and better teaching to the new generations coming into the trade!
Press fittings vs flowing nitrogen.. hmm Great detailed video, Thanks!
Really appreciate ur videos, they're so helpful.
I'm speechless, ty.
Much love, Craig!
Saturday school we here
Nice video. See some others on you tube pushing that stay bright. Uh-oh. Let Craig’s will be done
Very good i always said silver bearing solider better as I was brazing now we need a video brazing with nitrogen to the last fitting service valve need heat prof hoses thank you may Jesus Christ Bless you and family.
It would be more interesting and scientific to have a lab analyze the oil after contamination with varying amounts of flux then analyze the effects of the contamination on winding coatings. In a lot of cases it’s not worth it to be 100% perfect. You start getting diminishing returns as you approach perfection. This video is great for Internet arguments, but only partially scientific.
Excellent video. It's confusing to wait for the braze to "dry". You are waiting for it to freeze.
VRF system good
I love the detail to the copper fitting cleaning but let’s be honest in a real world scenario where pipes are often vertical and oily, doing this much cleaning is asking for extra trash in the system. Whether it be copper shaving or dust from the wire wheel this much cleaning is going to put stuff into the system.. But of course In a perfect world we would “clean it all out” before brazing.
Much needed video 👍
Much more copper oxide is formed if you’re raising the pipe in a vertical position . Heat creates a natural flu effect that causes the air inside the pipe to rise. This brings much more oxygen latent air flowing across the glowing hot copper producing a thicker layer of copper oxide inside the pipe.
Very good for presentation for students in class .
Nice information knowledge but brazing with nitrogen copper pipe any mistake hazard
Forgive me father, for I have sinned….
Really you think he's telling you to ask forgiveness on social media. Do you even read the holy book?? He says don't pay in the public but go to your secret place and cry out alone so this foolishness this isn't the place this a edifying video about craftsmanship. Peace be upon you go and learn don't repeat the and mistakes
❤
They do make acid free flux.
How do you flow nitrogen while brazing in a compressor or an expansion valve?
👌👌👌
What is your opinion of phosphor copper brazing rods
You bring it down to 200 on each install? I do residential installs
If youre pushing nitro through it wont all that junk just get clogged in the txv?
Anyone know the proper way to braze when replacing a compressor? I don't see any way to flow nitrogen.
