The process utilizes a mild acid electrolyte solution and DC current that when applied to a weld or heat affected zone (HAZ) very rapidly removes discoloration. On large construction projects utilizing austenitic, super-austenitic or nickel alloys, weld discoloration has historically been removed by mechanical polishing, blasting or a harsh chemical application, all of which alter the appearance when compared to untreated surrounding surfaces. UltraClean's process simply removes the color without significantly changing the appearance of the material where treated. As the name of the company indicates, UltraClean's highly trained crews perform in situ (in place) electropolishing for customers in the Petrochemical and Bio-pharmaceutical industries where most work performed takes place in a confined space using state of the art safety and worker comfort practices.
Electrochemical cleaning (ECC)tm of welds is a Proprietary Process unique to UltraClean Electropolish Inc. Developed specifically for removing weld discoloration directly on a weld, sheet or plate material opposite of where a weld has been made.
