55B007 - Surfox Angled Flow-Through Weld Cleaning Brush

Precision Electrochemical Cleaning for Complex Geometries

The Walter 55B007 Flow-Through Brush - Angle is a specialized accessory engineered for the SURFOX electrochemical weld cleaning systems. Designed to address the challenges of cleaning and passivating stainless steel welds in difficult-to-access areas, this brush features a unique angled geometry that fits perfectly into fillet welds, inside corners, and tight structural intersections. Unlike standard cleaning pads which may bridge over tight corners, the bristles of the 55B007 penetrate deep into the weld toe, ensuring complete removal of heat tint, discoloration, and surface contaminants.

Technically, the brush utilizes a flow-through mechanism that integrates directly with the SURFOX wand system. This design allows the electrolyte cleaning solution to be pumped continuously through the brush body and out to the bristle tips. This constant supply of fresh electrolyte serves two critical functions: it maintains the necessary chemical concentration for effective electrochemical reaction (cleaning and passivation), and it helps dissipate heat generated during the process, prolonging the life of the brush and protecting the base material. The bristles themselves are constructed from high-performance conductive materials capable of withstanding the acidic nature of the electrolyte and the electrical currents used in the cleaning process.

For industrial MRO and fabrication environments, the 55B007 represents a significant efficiency upgrade. It eliminates the downtime associated with manually dipping brushes or pads into solution, allowing for a continuous workflow. It is particularly effective for TIG and MIG welds on stainless steel grades 304 and 316, restoring the chromium oxide passive layer instantly upon cleaning. This component is an essential addition to any SURFOX setup, expanding the machine's versatility beyond flat surfaces and outside corners.
