Electrolytic Pickling
An electrochemical process for removing scale and oxide layers using direct or alternating current in acidic electrolytes. This significantly accelerates the cleaning of the metal surface compared to pure immersion baths.
Electrolytic pickling is a cleaning process for metal surfaces that works with electricity in an acid bath. It removes scale and oxide layers that would interfere with welding. The surface gets clean and you avoid later weld defects or corrosion at the seam. But be careful not to just copy the parameters for voltage, current, and time. They depend on the acid, the electrolyte amount, and the material. If you leave it in too long or apply too much current, the bath will eat away the base material. The connections must sit properly and the part must be fully immersed in the bath, otherwise the cleaning will be uneven.
