Anyone know about welding aluminum??
    #25102217 -

Long story short I bought a atv for my kids birthday and turns out the crank case is broken around the oil drain. He had it jb welded up. I'm a pretty good mechanic and all buy I've never welded aluminium, I've brazed before and wonder if that would hold... I'm not trying to split the cases and would appreciate any input.

Thanks.

Thats going to be tricky. I dont think alu is weldable by normal standards.

Cant you use some type of filler? Or maybe cast some molten alu into the crack?

I'll get some pictures when I can. It's more of a gap then a crack. I'm pretty upset about the whole thing.

I have a Hobart 220 mig welder. I wonder if I can get some aluminum wire for it?

without any pictures i would say mig welding aluminum is going to be tough as shit. dont want to blow any holes in it.

is the quad fairly new?
if it is, you can try calling a dealership and see if they have a bulliten out or a proper manufacture fix.

So the quad is a 1998 kawasaki bayou 300 2x4. It's overall condition is minty so something like this was never even considered.



Hard to see



Edit: here's a picture of the quad. Guess I just got bit on this one.

To weld aluminum with a MIG welder, you need a spool gun.

I've done aluminum on both TIG and MIG w/ spool gun. I thought TIG was much easier, but the spool gun I was using was kind of janky.

I'm starting to think buying a new crank case half is my best bet.

Maybe find a used one on eBay?

Or take it to a welding shop.

Is it definitely aluminum not magnesium?

Not sure about mig but both can be tig welded.
Magnesium can catch fire and run away from you tho.

Also if welding in place any trace of oil on the inside will contaminate your weld pool.
It's also a lot of heat you would be putting into it you might fry your seals anyway.

I would be taking it apart and getting it tig welded.

You want to have the right alloy of wire, just any aluminum wire will not work equally well. It should work fine with a tig but you are probably better off taking it to a place where they have done that kind of work before. Ask how many similar jobs they have done and maybe you can see some of their work in the shop

Update: I tried using aluminum wire and 100% argon in my mig welder, I practiced on a spare engine case... and it worked but is Not easy or for the inexperienced.

I tried alumi-weld rods but couldn't get the metal hot enough.

Long story short, a professional shop charged me 20$ to weld in a plug I drilled and tapped. Bam  new oil drain with No leaks!!!!


The shop owner said they have a older tig setup no one uses and I could buy it for 150$ if I wanted it.

I don't know shit about welding BUT my gut tells me you are going to need another metal to melt around the two pieces of aluminum.

They used al wire no doubt in their tig. The two pieces both melt where the arc is and the wire or rod fills in any gap and strengthens the area. Same with steel smaw welding and so on. Mig or tig are just more precise

Nah.You just need to be able to melt aluminum in an oxygen free environment.

In oil? In water? In nitrogen filled room while wearing a suit with an oxygen tank?
