Will this work? My tranny bellhousing has a hole in it. I went to home depot and bought burnzomatic aluminum welding/brazing rods and a torch. How well will it hold up?

A small piece of aluminum will be welded in over the hole.

I would only tig weld it. But then again its just the bell housing.

Yeah, all it really needs to do is seal it up from the tranny oil...

 

you cant weld Al with oxy. due to the melting temp of alum-oxide on the surface being a lot higher than Al.

ive heard all these rods you bought just dont work.

 

it's not going to work. the torch won't get the aluminum casing hot enough. now it's a different story if you have a oxy hydrogen setup and weld tips and some better rods. just pay someone to tig it up.

yes you can. I've seen it done. Do a couple google searches and you will see all kind of links about people doing it. Most of them are sculpture or bike repair links.

I wouldn't recommend it though in this case though. Just take the case to a welder and have him tig it.

 

It CAN be done, but if your asking this question you probably have zero experience with welding aluminium.

Tip 1... It's a f*cking Bitch to learn to do it properly, and you'll probably make it worse

Tip 2... Pay a machine shop 50 bucks or whatever and have it done right with a TIG, or MIG(little sloppy but works just fine)

Hopefully you'll take this advice

Yeah I should have stated that. THanks man. I think it's more likely that he would end up blowing a big *** hole in his bellhousing that successfully welding the hole shut. Just wanted to point out that it can be done.

 

Couldn't you just tape off the bellhousing on the inside and then fill the hole with JB weld? I dont know how big the hole is but it might work. Then maybe come back and pull the tape off the inside, scuff, clean and go over the edge of the hole. Doesn't even have to be JB but there are other aluminum filled epoxies that would do the same thing. Since it just has to hold oil I thought maybe this would be an easy fix as long as you prep it right. The welders out there might will laugh at the idea but I bet it would work.

 

of course it can be done. how do you think they welded aircraft parts when there weren't any electric machines?

 

Its on the inside of the bell housing and you can see the speedo gear when you look in the hole. So you cant jb weld it. It has to be covered in a way that wont interfer with that gear. Jb weld was my first idea for him thought.

are you sure thats welding and not a brazing process, such as the "aluma-weld" rods....because those are a brazing of sorts.

 

It was welded up by a buddy's shop teacher...

Fixed

Yes I'm sure everytime I'm welding thick AL in the shop and my dads friend is in there he keeps trying to convince me to weld it with the torch. I tell him he is old and crazy and I :heart: my tig. . You can also braze AL but it requires a silver alloy rod or something like that. There is a company local to me that makes all the brazing rods for that(ones that actually work lol)

OP: Pics of the fix???

 

you can also use an aluminum brazing rod.

id like to hear how he welds with a torch since the oxide has a much higher melting point.

ask him next time youre there would you?

Back in the day they used to make planes out of wood.
