Brazing Video

*sigh* Seems you forgot that pic... (not that I needed it)

Thanks for the video. If you still have the raw footage, you can send it my way and I can clean it up for you (might not be as sharp as Mr Pink's, but that depends on your camera). I do video editing/web encoding for a living. :D
 
Do you heat and apply silver brazing alloy to the other side of the joint? It looks like your only melting it onto the tubing?

The braze flows into the joint. I didnt take a picture of the back side of this joint but you would see that it has been sealed as well. The reason it looks kind of "puddled" up is I used too much braze.

If you look at the back side of your joint and see that braze has not flown in there, one; you are not heating the joint evenly or enough, and two; you need to rebraze it from the back side. it takes some pratice, I still do some sh!t brazes now and then.

Also, make sure your flux liquefies and flows into the joint before you apply the braze, this will ensure a total bond.

stay safe kiddies.

simple, yet effective! I like it. The way you made it sound, I thought the vid would be 10 minutes long, but 20 seconds is all it takes!

Thanks!"thumbsup"
 
I never could braze as good with the tubing laying on the table, as the metal it is laying on takes heat away from that joint...Also, looks like you could have "fishmouthed" the tubing better in that first and 2nd pic. Looks like to much of a gap on the inside "thumbsup"
 
what diameter solder are you using? i got some thick stuff that i cant hardly melt now. 3/32 i think it is.maybe 1/8. close to it.

just using mapp gas with the stock head. not to adjustable.:-(
 
I haven't seen anything but 3/32 or 1/16. but it should say it on the canister in came in.
Well is it harris or something else. can you post a pic of what you have?

I've never had a problem with my unadjustable heating torch.
The only other time I use anything else is with thicker material that takes forever to heat up with just a normal set up. Then I use the mapp/oxy mix for higher heat out put.

I also try to suspend my pieces above my metal table so the aluminum doesn't take some of the heat.
 
can't find the raw footage but I plan on making another soon hopefully I'll get a better out come or visually be able to see it better.


sorry about the pic other things came up and I just forgot about it.:roll:
 
Ok guys, I merged your 2 brazing video threads together and made it a sticky. You can keep adding to this thread with more tips/tricks. "thumbsup"

Mrpink.

i dont have the adjustable tip. it is low flame. should be the problem i thnk.lol
 
This seems very much like 'sweating copper' without the risk of leaks.

Thanks for all the great info. I was really getting tired of burning my tube with my mig.
