Welding/two types of aluminum


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?



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

Also here is an older publication by Lincoln Electric on aluminum welding

Hope this helps.
