How to Solder stainless steel
This video tutorial is in the Electronics category which will show you how to solder stainless steel. For this you will need silver bearing solder. Harris #8 StaBrite is good, but it is expensive. Plumber solder works fine, but make sure it has silver in it. Use Harris Stay Clean liquid flux. All the surfaces have to be clean and sanded. In this video a pipe is being soldered to a metal sheet. Apply some liquid flux to the outside of the pipe to be soldered. Make a neutral flame, heat the pipe and apply the solder on the outside of the pipe. Apply some more flux and heat the pipe so that the solder flows on to the sheet.
