Question
Is it feasible to weld 6061 to 5154 aluminum.  6061 is a heat treatable alloy whereas 5154 is not.  Is this practical or is this fought with potential problems?

Thanks

Al

Answer
5054 is not an alloy I have heard of.
5052 is a very common alloy for cold formed sheet metal projects.

5052 is easily welded to 6061 using 5356 filler.


Alcotec is an aluminum filler metals manufacturer with excellent technical info pages
