Anyone has any experience with aluminum spot welding
I have 21700 batteries with an aluminum cover (positive pole / plus).
They have to be welded.
Now the question is can I weld the wire with securing wire (normal metal) or with an aluminum wire.
And if so which devices work and has someone already done it and can give me tips.
(In any case, soldering is not possible because aluminum does not accept solder, I still tested it, but I tested it again.
