  • Aluminum&Steel, Stainless steel

    How can u weld together two different pieces, one made of aluminum, and one made of steel or stainless steel??? Do you use AC or DC??? I'm really interested in that so please any suggestions??

    Aluminum melts at half the tempurature of steel (mild or stainless) so I would be VERY surprised to find they could be fused as one. Moreover, Aluminum likes AC, but Steel likes DC.

    Perhaps a laser welding machine could do it.

      Not to mention that one is ferrous and the other is non ferrous. I'd use a drill and bolts.

        you can solder or braze to connect different metals together. aladen has an aluminum brazing rod thats supposed to do a good job of that. but you cant just TIG them together.
        steel to stainless steel is doable. but not steel and aluminum.
        here is a link to them, they can send you some info on brazing aluminum to other metals.

            Some 20+ years a go I preformed a test procedure for the Government and a university.
            It joined 6061 t6 aluminum to a36 mild steel.

            It took some dozen or more steps alloying each material with fillers until I had two similar enough materials to join.

            It was an all GTAW process preformed in an inert gas chamber.

                  welding aluminum and stainless steel together

                  It is posible to weld the two metals together. you use the same process that the makers of fancy frying pan makers do. its called explosive welding. two diffent types of metal are joined together under a controled explosion. it generates preasures of about one million psi to fuse the materials together. i wouldn't recomend trying this at home...try your neighbor's house instead...lots of info about it on the web..
