Patching a hole in my aluminium pot?

Hey!

I have a small crack in my aluminum brewing pot. I need to patch it. What can I use to patch it that'd be safe for cooking and would be able to withstand heat?

Aluminum is very hard to weld a good fix, unless you are an expert at MIG welding, and can do it where food doesn't lodge in the crack between the pan and the patch. If you are good at MIG Al welding, then it might not be tough... just make sure your core metal has no lead in it.

TIG weld it and grind it smooth.

Just replace the thing. Add up the time and expense of repair, and the chance it will have further problems - not worth it.

I haven't either. But it's what I'd try first because it's in my plumbing toolbox.

+10000. What are you going to pay for a new pot like maybe $5.00? I doubt the thing is of any quality if it cracked.

It should stick. You are going to have to get that pot very hot for it to work. But I would not want to eat anything you cooked in that pot after repair. No telling what would be released into the food, even if the repair held at all after the pot was heated for cooking.


Just buy a new frigging pot!

I'd consider a new pot as well because aluminum is hard to weld, and the MIG kit requires special Al wire, and pure argon gas. However, I was assuming from the OP that replacement wasn't an option.

Careful on solders though... Lord knows what may be in it, unless it has some food grade label, or an ingrediant list.

TIG welding is the best way to fix cracked aluminum but the heat treating will never be the same.

Not if it has water or coffee in it. The heat would be conducted away too fast. It's impossible to solder a copper connection if there's any water in the pipe. The solder might work in a plug-like fashion. Silver solder is non-toxic, which is why it's used for drinking water supply.

Now you have. Admittedly, the Alans were glued.
