  • Tig welding pop cans

    What kind of aluminum are pop cans are made of? Do they require any prep work or can you just start welding them? Please make your suggestions. Feel fre to post pics of any you've done. Oh yeah I was thinking of welding the bottoms together.

      Check out the thread Passenger started and look at the photos of the pop cans and razor blades.

      I would suggest you PM him for some guidance...

        One word of caution on welding pop or beer cans. They both have an epoxy resin type coating on the insides and outside. The inside to protect the contents from picking up metallic taste. And the outside to protect the screen printing ink with the logo's etc.
        So you might want not to breath the fumes coming off them.

        You want to do some thing hard do like Ron Covell and TIG weld two pieces of aluminum kitchen foil. Now that really blows peoples minds, Of course there is a trick and it is two heat sink strips holding the two sections together with about an inch above the bars of metal. Torch along the top of the bars, burning off the section above.
        Lowest amps and move fast no filler rod required. He shows it in his TIG welding video they sell on this site.

          The bottom ring has a coating too, to aid in movement in the factory.

          Thats what I do for a living. 6,000,000 cans in 24 hrs. 24hrs a day 7 days a week. there is a fair amount of aluminum in the chime(bottom) of the can.

            If you take a red scotch brite pad, you can get the coating off the outside, and if you have good enough amperage control, you can weld along the side of it. It isnt the best weld, but it does impress people.

            It might be in the thread that was already posted, but someone welded a scrap piece of AL to the side of a can...THAT impressed the **** out of me.
            Precision is only as important as the project...if you're building a rocket ship...1/64" would matter. If you're building a sledgehammer...an 1/8" probably wont.

                      I agree he didn't really say anything pertaining to the original post nor any posts made after that.

                      Welding the bottoms of pop cans together takes an experienced TIG welder with lots of aluminum experience. I've been welding for 35 years now and don't know if I could do such a thing as most of the materials I weld on are 1/16 and thicker. If I were to try though I'd probably use an .040 Ceriated tungsten and .030 filler wire. I'm not sure my 340 A/BP will go down that low in amps to try it and I don't have access to an inverter machine. In fact I've yet to weld with an inverter.

                        Welding the bottoms of cans is faily easy. If you can weld to the sides.... thats impressive.

                        Just use the same practices that you would use on any critical weldment. Theres no tricks to welding the bottoms.

                          Are you using an inverter or transformer welder? I have an old transformer welder from the early 70's and I don't think my amperage will go that low. I may order some .040 tungstens and give it a try. I know a member here who can weld gum wrappers (back in the day when they had thin aluminum foil on them).

                            No one's ever offered me a red cent for welding pop cans together, so I don't do it.

                            Course, if there's a market for this, I'll have to look into it.

                              Hey Sundown

                              How about you weld up a bunch and I'll give you a cent or maybe two for each. Then I can set them around my shop and tell all the boys, see, I can weld pop cans and you can at least make something. Since I haven't had any success after about half way around, I think it is out of my league.
