Pickiling & Passivation
Stainless steels rely on a very thin surface passive film for their corrosion resistance.
It is vital to maintain and preserve the integrity of the passive film. When a Stainless is welded this passive film is damaged and the affected areas require repair by pickling & passivation which is achieved via a dip system. Once this process is complete a constant and sufficient availability of oxygen at the surface of the stainless steel must be achieved for best results.
