🔥 Gas Brazing Technique

What's the difference between welding and brazing, and when is it acceptable to braze a part over welding it? In this video we will go over braze techniques, melting points, chemical composition and everything else you need to know to start brazing with your oxy acetylene setup.

i'm watching this for my welding class and his voice and the crackling of the torch is just, so, soothing, to the point where its hard not falling asleep.

As an A/C guy, I also enjoy brazing. This is not quite the same, as my brazing is non-ferrous, but that’s exactly why I’m here. I love your instructional videos! Thanks

I learned to braze almost 50 years ago and it is still a great way to repair broken cast iron..The problems people encounter usually stem from not cleaning properly, too much heat, not enough flux, etc.... Cheers; Mike in Louisiana

Glad you still stress the basics which gas welding teaches. I'm almost sixty and my first welding class in high school was gas welding and I'm thankful I learned, it made learning all other welding process easier. I also still do repairs and some artistic projects with brazing and soldering, I find it calming.

Bob, you made that braze look simple and clean. I think that if I practice about 47 bazillion hours, I might come close. Thanks for your excellent videos!

this guy is a great teacher. one detail for those who are interested - it is not capillary action that joins the surfaces, they join as a result of molecular interaction of the liquid metal with the solid metal, caused by wetting.

I learned more in 14.5 minutes here than I have in the last year trying to learn this through practice. Thank you so much!

2nd best channel to learn anything related to welding brazing soldering. Your students are lucky to have such a great teacher with a wealth of knowledge. Who is

[richmac]

Thanks for doing this video Bob. Haven't brazed in about a thousand years but can remember using it on a lot of things in the past and recall admiring how surprised I was at the strength of the bond. I hope the students attending your class realize how lucky they are to have someone like you teaching them.

Started gas weldng/brazing this weekend. Your video has helped in knowing what I SHOULD be doing and what to expect when it is done correctly.

AHH the great smell of brazing , The oxy acetylene process/ brazing was the first welding process I learned in vo tech. Many people dont realize the incredible strength of brazing I remember brazing broken gear teeth that saved thousands of dollars. To replace the gear was over $2700 dollars and to repair it was about $20.... great job.

Its such a pleasure to watch your videos. Its obvious that you are passionate about your trade and a great teacher. Thanks for doing what you do!

[evilbrat]

So happy to see and hear someone still teaching base welding tech. Gas [oxy-act] along with brazing. Low Fuming Bronze brazing is what I learned first back in '75. Glad I rolled into your channel.

[timscates]

Genuinely love your guy's videos, old and new. Your use and expertise of not only the welding methods and knowledge but also the camera footage you provide makes it so much easier for me to learn how to do these processes myself. Thank you!

[robertberry]

Oxy acetylene, or gas welding and brazing is great! I learned it first along with cutting. Then I learned using propane. It is still my failsafe go to. I will never forget the comments the first time someone watched me literally weld a copper heat exchanger with gas. I use a lot of high tech today but still love old school gas.

Keep your great videos comming! You are doing the trade a great service by being a excellent teacher!

[victoryfirst]

Thank you for showing us all how to make brazing happen. This was taught when I was in school metal shop. Some of the fondest time spent in shop class. Today they do not even have shop classes or even music class so i am told. Nicely done fella too.

[ddistrbd]

I truly dig this tutorial, it shows or teaches so much in such short time, the distance of the tip not being constant was the biggest tip I learned. I also watch your videos more than others because being left handed, I can mimic/ follow your movements easier. overall, everything makes more sense. thank you.

[sethwarner]

Thank you for taking the time to show this craft. I don't know how to braze. I am a woodworker who wants to make my own bandsaw blades. I also want to repair broken bandsaw blades. This requires brazing.

[raulbocanegra]

Thank you for taking the time and effort to make an educative video in which we can learn the science behind “welding”. You show that it’s not just what you learned watching others weld but the fact that there is a science behind all. Thank you.
