    Default what alloy to weld this two metals?

    I have a piece made of aluminum 3003-h14 and an extrusion made of aluminum 6063-T5 that is going to be welded perpendicular to it, which is the correct alloy to do it?

    Also, if I change the piece made of 3003-h14 to a one made of aluminum 50582-h32 and again is to be welded with a 6063-t5 perpendicular to it, will have to change the alloy? or all the aluminums can be welded with the same alloy?

    Thanks

    I would use the 3XXX and 4043 filler, here is a good link to check http://weldreality.com/aluminumalloys.htm

    Default aluminum

    what is the application going to be like?

    4043 is a universal due to low melting temp, but it has low ductility and cant take a lot of cyclic loading.

    You may want to use the 5xxx and 6xxx series together with 5356 filler.

    The application will dictate the filler.
