55B005 - Walter SURFOX Flow-Through Cleaning Brush

Optimized Electrochemical Cleaning Performance

The Walter 55B005 Flow-Through Brush is a specialized accessory engineered for the SURFOX series of electrochemical weld cleaning systems. This component is integral to the high-efficiency passivation processes required in industrial stainless steel fabrication. Unlike static pads or standard dip-brushes, the 55B005 features a flow-through architecture that interfaces directly with the SURFOX wand system. This design allows the electrolyte cleaning solution to be pumped continuously through the core of the brush, saturating the bristles and ensuring that fresh fluid is always present at the arc zone. This continuous flow is critical for maintaining the electrical conductivity necessary for rapid oxide removal and for cooling the workpiece to prevent micro-pitting or burning.

Constructed from high-grade conductive fibers, the brush is designed to withstand the aggressive chemical environment and high temperatures generated during the electrochemical process. The fibers are sufficiently rigid to provide mechanical agitation—helping to dislodge stubborn surface contaminants—yet flexible enough to contour to complex geometries such as fillet welds, inside corners, and pipe intersections. This adaptability ensures that the entire heat-affected zone (HAZ) is treated uniformly, restoring the chromium oxide passive layer effectively. The 55B005 is particularly advantageous for applications involving TIG welds where aesthetic finish and corrosion resistance are paramount. By utilizing this brush, operators can achieve a consistent, high-quality finish that meets ASTM A967 and ASTM A380 standards for passivation, without the safety hazards associated with hydrofluoric acid pickling pastes.

Integration with the SURFOX system allows for precise control over the amount of fluid dispensed, reducing waste and minimizing cleanup. The brush's durability ensures a long service life even under continuous industrial use, making it a cost-effective solution for high-volume fabrication environments. Whether used on the SURFOX Mini, 205, or 305 units, the 55B005 remains the standard for precision weld cleaning.
