The SURFOX™ 304 from Walter Surface Technologies is a system for removing heat tint from stainless steel welds (GMAW, GTAW, and spot welding) without altering the surface of the parent material. The system removes surface contaminants and promotes the formation of a uniform and durable chromium oxide layer to protect stainless steel against corrosion.
According to the manufacturer, dual inverter board technology makes this unit the most efficient weld cleaning system on the market and ensures that there is no micropitting on the surface. Two different modes can be used: AC mode for cleaning or marking and DC mode for polishing or etching.
The system conforms to the ASTM A967 standard for chemical passivation of stainless steel, and the cleaning electrolytes are NSF-registered and safe for use in food plants. The system serves as a fast, safe alternative to pickling pastes or abrasives, the company states.
