i have to weld a 90 elbow onto a turbo housing. I will be using a dynasty 200dx with 3/32 red. Any tips for settings or suggestions for welding cast aluminum?

 

wire brush it good with a ss wire brush.
pre-heating will help.
use green (pure tungsten) if you have it rather than red.

here's one i did a while back:

 

DO NOT, use a green (pure) tungsten with your dynasty!!! Good way to hurt the machine.

Green tungstens suck anyways, use a ceriated or zirconiated, zirconiated makes for the best welds especially with inverter machines.

Grind the area you going toweld, make sure its fresh and clean, and have at her.

that excatly the direction i need to go. is that just a but weld using the same ID as the turbo? I do have 1/16 ceriated as well but i think that might be to small

 

1/16 is too small, use 3/32 and either 1/16 or 3/32 5356 filler. I recommend zirconiated for the dynastys especially. I do this modification to turbos fairly regularily with my dynastys (2oodx and 300dx). Runa bout 140-150 amps, balance at 70, freq at 200. After you prep the joint use some acetone on it and your filler. Should come out nice!

Thanks for the help everyone ill look into getting some ziconiated

What do you think about vbands for this aplication? I never used them before?

 

Just curious, how would a green tungsten hurt an inverter machine?

 

wouldnt hurt the machine but go ahead and try it....you wont have much tungsten left.

When I use inverters I typically only run ceriated or lanthanated for AC and DC applications. Zirconiated works great on transformer machines though.

 

Why not just run a 90deg coupler?

It's not as cool dude...duh.


Why does everyone love green tungsten so much? I don't even know anyone in real life who uses it on a transformer. I used red 3/32 for damn near everything when I was tig welding. From mating the business end of two razor blades to fixing cast AL transmission casings.

Eh anyway, Dave got you all set to go.

If there are casting flaws that pop and get all nasty you can run a couple of passes with no filler to boil them to the top and then grind(or file) them off. Shouldnt be that bad on a turbo housing though.

more expensive and not as durable

I agree.....green sucks, and is essentially old outdated technology.

 

i use 3/32" 2% with everything on my invertec with out issues. but i may get some ceriated and see how it works with aluminum or some zirconiated if it works as well as u say it does dave.

Ceriated and Lanthanated are what the miller rep suggested to me on the miller inverters at least.
