The Walter SURFOX™ 305 is a electrochemical weld cleaning system for stainless steel and aluminum. It quickly and easily removes heat tint from the heat-effected zone of MIG, TIG and spot welds, cleaning the surface and allowing passivation on stainless steel to begin without altering the surface finish

​

What is weld passivation?

​

     Long story short, passivation is the reason why stainless steels remain corrosion resistant for so long. To be in a passive state, a thin layer of chromium oxide has to form on surface of the metal. This is achieved through the process of passivation.

​

     The integrated tank and flow-through system ensures the electrolyte solution is delivered directly to the work piece, minimizing the potential for spillage or cross-contamination.  The dynamic current control also ensures that the electrical current will not cause micropitting on the surface.
