Aluminium Welding with rods

Recommended Posts

I’m thinking of having a go at repairing my tub using Ali welding rods but when filling in small holes I’ll need something on the back to stop the molten Ali from dropping through until it cools.

I know from discussing mig welding that you can use a piece of copper to do the same job but will copper also work with Ali and not stick to it or do I need to look for some other metal?

I used this technique to do exactly the same and it worked well. I had never welded ali before.

 

I changed to a teflon liner in the MIG and changed the gas and did it that way. Didnt produce anything pretty but was successful and you are only going to grind back off flat anyway
