How to Braze

Too much heat young fella

When the braze is running down the pipe, it’s way too hot, lol

That heat on the copper took way too long, surprise he didn’t put a hole in it

This guys a rookie forsure

He will get better eventually, but he has a long ways to go.

You guys really should be wearing safety glasses.

How about a neutral flame?

Decent pair of shaded safety glasses will dim the light/help you see the color change in the copper…you’ll get a better idea of when the heat is just about where it needs to be to start adding phos/silvaloy. I know it was mentioned, but I wish they also showed how nitrogen purging keeps the inside of the tubing cleaner.

Well I hope you have real world medical when that kid losses an eye .

Where's his PPE oh I see it on the table..

Please teach braze titanium.

Probably shouldn’t point the tip right at the lines that look to be very close.

is the for real?

You got to be kidding

That was entertaining. LOL

You had no eye protection. You used the wrong type fittings for brazing since you used deep seating fittings designed for plumbing solder, there was too much heat which makes the copper dead soft and 50% weaker, you cooled the part with water that makes the braze ubber brittle. As another person said so eloquently: you have got to be kidding. LOL

To much flame... No good

He's taking too long to solder one joint

I learned to braze way back in my freshman year in high school. I'm 58 now and own my own residential appliance repair business. I'm not sure what "your" qualifications are, but I have to point out a number of mistakes. Way too high of gas pressure. If it sounds like a jet engine and you're not using a rose bud or a cutting torch, it's way to high. You are also keeping the heat on way way too long. All that darkening we see on the outside is also on the inside. You need to concentrate your heat to a point and work more quickly. Looking at your piece after you're done and especially after cooling it (for no reason), it looks terrible. You should be embarrassed being a representative of Johnstone. Sorry, but I'm just being honest and it irritates me when people like you appear to be professionals and our younger techs don't know any better.

Very bad technique 😂
