How do you finish stainless steel after welding?

The best way to clean stainless steel after welding is through a process called electropolishing.

This process involves the oxidation of an acidic electrolyte on a metal surface with the help of electricity.

 

Can stainless steel pipe be polished?
Stainless steel pipe doesn't look all shiny and new right off the welding line. In fact,

it looks burnt and kind of charred. Polishing it will give it that mirror finish (or satin silver

finish) that makes it such an attractive accessory.
