Walter Surface Technologies Improves Weld Cleaning with Non-Toxic Alternatives

Walter Surface Technologies announces the arrival of new components to the SURFOX weld electro-cleaning system. This latest innovation from the company underscores Walter’s commitment to “Making Green Work.” The new Surfox system is just one more solution that helps create a clea Getting Back With Ur Gitl ner, healthier, and safer industrial work environment.

Traditional weld cleaning methods are highly toxic, wasteful and inefficien. While welding stainless steel often leaves heat discoloration (blueing) on the finished surface, metal fabricators are facing an increased demand for stainless steel that has a clean, fully passivated surface – for a wide range of industries such as food and beverage, pharmaceutical, architectural and transportation. To satisfy customer demand, metal workers must remove these discolorations. But the traditional cleaning methods that use pickling paste or grinding machines have high environmental impact and labor costs. Grinding is not only time-consuming and labor intensive, but mechanical heat discoloration removal fails to provide a clean, aesthetic finish. Cleaning heat discoloration with pickling paste is the most common chemical method, but the pastes can be difficult to apply evenly, so the worker risks using more than necessary or insufficient amount of paste in some areas. More importantly, though, pickling pastes are dangerous. Not only are they known carcinogens, but these extremely acidic compounds cause severe chemical burns when in contact with skin; workers must be covered from head to toe in acid-resistant overalls, gloves, and ventilation masks. Finally, the heavy metals in the pastes must be separated from the cleaning residue prior to waste disposal, adding another step to the overall production process.

Surfox: the Walter alternative

Walter’s Surfox system cleans stainless steel without toxic pickling pastes, saves time for workers, and is easy to use. In a typical application, the worker fills the cleaning unit with an electrolyte cleaning solution. When switched on, the unit pumps the solution through an application pad, which simultaneously cleans and passivates the part. After the electro-cleaning process, the worker applies a neutralizing fluid to remove acid deposits. The improved Surfox system features a new application pad, which is four times more conductive than the previous one, and can clean surfaces at rates of three to six feet per minute. The controlled dispersion of the cleaning fluid also prevents waste. The result is a flawless finish on stainless steel – with Surfox, even a mirror-like finish on chrome is possible.

The Surfox system’s new components are:

· Surfox H – the standard electrolyte cleaning solution for regular use cleans up to 3 to 6 feet per minute.

· Surfox T – the electrolyte cleaning solution for heavy-duty jobs has a higher pH than Surfox H and cleans up to 3 to 6 feet per minute.

· New application pads for all cleaning units have increased conductivity. With this practical cleaning method, results are visible almost immediately.

· Passivation tester provides numeric values of state of passive layer

· Stainless steel grade ID tester allows customers to instantly identify the grade of stainless steel

· Marking kits electrochemical process to permanently mark stainless steel surfaces (for barcodes, serial numbers, lot and batch numbers, text, company logos, etc.)

Metal fabricators who use the Surfox system save time and money, improve working conditions, and reduce their environmental impact. In fact, 70% of new customers abandon traditional methods in favor of Surfox.

Surfox system is NSF certified for use in the food industry and ASTM-A967 / ASTM-A380 certified for chemical passivation on stainless steel.
