How to Solder Aluminum Cans


When you are creating a multimedia art project, you may feel hindered by the lack of adhesives available at an art supply store. This can be particularly frustrating when you are working with non-traditional art materials such as aluminum cans. One solution is to use a soldering iron with special aluminum solder to seal the aluminum cans together. This will allow you to create art out of recyclables without concern that the project will fall apart.

Things You'll Need

  • Aluminum cans
  • Vice
  • Rock
  • Soldering gun
  • Aluminum soldering wire
  • Clamp an empty aluminum can vertically in a vice then clamp the vice onto a tabletop.

  • Place a second aluminum can vertically on top of the first can, lining up the ends so that they are flush with each other. Place a rock on top of the can to hold it in place.

  • Plug in a soldering iron and allow it to heat up for 10 minutes.

  • Hold a piece of aluminum solder against the seam where the two cans meet, then touch the soldering iron onto the exact area where the solder meets the cans. This will cause the solder to melt and to adhere to the can.

  • Repeat this process around the entire perimeter of the seam until the seam is filled with aluminum solder. Allow the solder to cool which will connect the two cans together. Repeat this process to connect as many cans together as you prefer for your project.
