I'm about to install an intake air temperature system that came w/ an aluminum bung

I do not have a DC Tig welder for aluminum, but saw on youtube that you can braze aluminum and it's decently strong.

Would brazing the bung into my charge pipe hold for 12 psi of boost?

Thanks

Gas torch welding aluminum is very difficult I would get someone to weld it up for you or buy a spool gun machine they work well.

Torch brazing and torch welding are different. Brazing is easier and will be plenty strong.

What is this wizardry aluminum brazing you speak of? post a vid of process pls

Maybe the guy doesn't know what he's talking about? idk, I just want to get this aluminum bung in the charge pipe without having to find someone to weld it in lol I only have a cheap Harbor Freight welder, I don't think they make a spool gun for it

That isn't brazing
brazing is with brass
that is a glorified solder joint that you could easily break with a pair of pliers or a quick hit with a small hammer
just take it to a shop with a.c. tig welder and if you've already cut and fit the bung they will charge like 30 bucks

Yep thats what I thought. Good luck if you use that process, I never had any luck with it, it aint new by any means. Spool gun or Tig gets my vote

What a joke! Neither welding nor brazing! Welding fuses the parent metal with filler, brazing uses brass rod. NO exceptions!

You can DC tig weld Aluminum with helium, its just doesn't have any cleaning action.

Actually brazing is used for all types metals not just brass and you can braze aluminum. Brazing doesn't melt the base metal so it's a somewhat weak joint but should be able to hold 10-20 pounds of pressure if done correctly. I used the braze metal roll cages together for my RC cars/trucks and they would take a beating and never came apart. The trick is to find the filler that will in basically hold to the base metal being used.

The term "brazing" has to do with the filler metal, a brass alloy. If that is not the filler metal, it ain't brazing...

Maybe in the past not anymore. It's one of those universal terms now.
You can buy brazing rod in Aluminum Copper Brass and many others.

Brazing - The American Welding Society (AWS ), defines brazing as a group of joining processes that produce coalescence of materials by heating them to the brazing temperature and by using a filler metal (solder) having a liquidus above 840°F (450°C), and below the solidus of the base metals.

I have used that stuff. it's pretty strong. Give it a shot.

I didn't end up using this method to install the bung, but out of curiosity I did try this method to patch a hole in an aluminum intake pipe and it worked very well. It was very strong

Yeah I used it to piece a chunk of a pulley wheel for a drill press back together. Worked f'n great.

Gotta love newer tech! How long has this been around? If you say more than 30 years I'm gonna feel REALLY OLD! lol

nah i saw it at a tradeshow only a few years back. yeah it's good **** if you gotta fix something thats made from mystery cast Thaitanium or Chinesium.
