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.

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.

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?

All welding is shielded from oxygen in one way or another. Most use a heavier than oxygen cover gas such as Argon or Carbon Dioxide to cover the weld pool.

Even welding processes that don't use a cover gas still need a layer of slag or flux to shield the weld pool from the atmosphere while it cools.....

Nah you don't need an aquarium but you need to know a little magic to be able to cast the right spell.

No, the gas covers the weld metal and also cools it so you just move your electrode and gas goes out automatically. It comes through the pistol grip on mig or tig. Co2 is about the cheapest gas.

In Patlal's alternate dimension we could put a gigantic aquarium on the moon to do our underwater welding very cheaply.
