I do HVAC work and have for about 19 years now so this is my bread and butter. But because of this, I was able to catch on to tig welding rather quickly. Enjoy!
@@alnov91 the technique in the video is not very good. He didn't have his copper hot enough & was trying to melt the rod onto it. That is not effective & looks bad afterwards. This type of brazing takes technique developed over time & exposure to various applications.
Coper ions make the flame green. Green flames are a sign that you have impurities of ionic copper compounds (oxides). Oxides are bad since they prevent a good bond between the base metal and your filler (braze/solder whatever).
Not to mention hes actually attempting to push the metal with the flame to a colder spot. Flux can be applied at that point to get the desired flow. This boy is dry lubing it and it clearly didnt work hence the cut frame.
@@Bishopgoldy it does not say otherwise. Phosphor works as the flux when brazing copper to copper. This range of alloys can have a multitude of (P) content and so, different ranges of fluidity. If it was not self fluxing, it would not adhere to the base metal due to oxidation on the top layer. We can add flux if we expect to heat the base metal for an extended period of time or if it is not clean properly.
For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord. (Romans 6:23) Therefore also now, saith the LORD, turn ye even to me with all your heart, and with fasting, and with weeping, and with mourning: And rend your heart, and not your garments, and turn unto the LORD your God: for he is gracious and merciful, slow to anger, and of great kindness, and repenteth him of the evil. (Joel 2:12-13) I tell you, Nay: but, except ye repent, ye shall all likewise perish. (Luke 13:5)
Soldering is when You join different types of metals together by melting solder, at a much lower temperature. Brazing is when you join two or more metals together with molten filler meta at a much higher temperature.
More heat sir, more heat.

Sheshh protect them hands brotha
1 year of hvac work and i was thinking i dont think thats hot enough then i see the experienced people saying it lol
The light in my shop washes out the heat color... It was hot enough
Why would you use a heat tip?
A 20mm tip would be sufficient to braze, a heat tip is better for un-sweating a weld.
I was thinking the same thing..
I build induction tooling so it is essential to be proficient with 15%, 45, 56 to name the common alloys. There's also brass & copper tig.
Example cupronikel
😊
Is this most efficient technique?
@@alnov91 why not ???

there's an art to THAT! season greetings Sir
crawford out 🙏🏻🔥⚒️🧙🏼♂️
Conhecimento é poder
Conhecimento muda nossa realidade
Sucesso infinito 🇧🇷🤝
Really enjoy a welding video without re**rded music thank you
Saan po nakabili ng tanso n panghinang
Blazing probably the most common weld I do day to day.
I thought he was going to do it right at the beginning😂😂😂😂😂😂
Your receiver metal is not hot enough, get that copper almost red hot and then braze, the green flame is a bad sign
Copper burns green, that’s where the color comes from, but yeah that joint was way to cold to add filler
Coper ions make the flame green. Green flames are a sign that you have impurities of ionic copper compounds (oxides). Oxides are bad since they prevent a good bond between the base metal and your filler (braze/solder whatever).
What is the thickness of this metal?
Is the filler rod a strip of copper?
Gotta get the metal hot first
You gotta keep the heat on just the right amount, if you get it too hot it'll stick
So, I learned to do that when I was 10 years old
Cool!
I brazed a copper windchime and it looks burn to all hell lol
Just weld it
acetylen or map gaz ?
Oxy propane
I learned how to do this at 12😂
What kind of flames
No flux?
copper-phosphorous alloys are self fluxing in copper to copper joints.
Mmmm the lack of flow says otherwise

Doesn't look like brazing to me. Way too cold.
Silver brazing with a rose bud..???
No..!!!!
Tutorial fail brazing
What's the thickness of his hands😅 what's the thickness of the metal what are beast
Начал горелкой закончил резаком
Welding tip what it's,.... Without head or nozzle less
Heat your base metal to cherry hot. What the heck?
Work me sir Cilver road brazing coper

Filler number
Use borax
So what is the difference between brazing and soldering, and why choose one over the other?
Solder when line is not pressurized
From my little experience, soldering is power temperature and not as strong.
Soldering is when You join different types of metals together by melting solder, at a much lower temperature.
Brazing is when you join two or more metals together with molten filler meta at a much higher temperature.
Artisan brazing guys.
Not a critical HVAC don't flood the building kind of thing.
Go easy he does great work.
Heat your base metal dude
Основной металл не прогрет,аты уже присадку суешь,олень
