  • 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

      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.

        Thanks for your answers, it will be a fan wheel, which will have 12 blades and rotating up to 2400 rpm.

        Thanks
