During the process of welding, the metal often gets tinted and discoloured. To get the shiny look back to your welded metal, you must remove the layer of discolouration. There are many ways to polish stainless steel after welding, but the most common is electrochemical cleaning. It is a fast and safe method that doesn’t pose any potential risk to the welder, unlike some other techniques. The welded metal is submerged into an electrolytic cleaning fluid, and an electric circuit passed through the liquid. This clears the impurities and removes the discolouration caused by welding.
