Develops Pro Inox Electrolytic Weld Cleaner and Passivator to achieve clean, corrosion-resistant welds.
A smarter, safer approach to stainless steel weld cleaning.
Scientific Engineering is a leading manufacturer and design company of commercial appliances and laboratory and scientific equipment. Established in 1966 the company manufactures its own range of products which are marketed through a worldwide dealer network. In 1993, a South African catering distribution company approached the Scientific Engineering team with a proposal to develop a range of equipment for the food service industry. The company branded its new range of equipment Anvil, and the name and products have now become synonymous with the industrial food service equipment in South Africa and worldwide.
“The way we manufacture our type of laboratory and scientific equipment is very similar to the way you would manufacture food service equipment. Simply put, the shell or body is made up of sheet metal components that have been either cut to size, pressed or bent, based on the shape of the component and then assembled with the various electrical, gas and other accessories being incorporated,” explained Brett Egerton, Sales Manager of Scientific Engineering.
“Because of the industries we supply most of our product is manufactured in stainless steel. Stainless steel continues to gain popularity in applications across the fabrication industry, mainly thanks to its corrosion resistance, strength, and toughness. Compared to mild steel, however, the material poses some welding challenges, especially for less experienced welders. Stainless steel can be three to five times more expensive than mild steel. Any welding mistake can compound the overall costs for rework.”
“Choosing the right welding process is key. There is a give-and-take with every option, and no single process provides a perfect solution. To determine the best option, fabricators need to consider the upfront cost and characteristics of the filler metal, required productivity, equipment complexity, and operator skill set.”
“In stainless steel fabrication, achieving clean, corrosion-resistant welds is essential, especially in industries like food processing and pharmaceuticals. Traditionally, this meant using harsh pickling pastes or time-intensive mechanical methods.”
“We have been able to import equipment to help us achieve the results that we require but as you know importing is expensive these days. This led us to develop and manufacture our own product. We launched the Pro Inox Electrolytic Weld Cleaner and Passivator to achieve these clean, corrosion-resistant welds a few months ago.”
The Pro Inox Electrolytic Weld Cleaner (EWC) offers an alternative that’s both safer and more efficient. Instead of relying on corrosive chemicals, the EWC uses electrochemical cleaning. A low-voltage current runs through a carbon brush dipped in a special fluid, removing weld discoloration and oxidation in seconds. The process is fast, precise, and leaves the metal with a bright, natural finish.”
“What makes this system stand out is its dual-user design and adjustable power settings. This allows two operators to work simultaneously, improving throughput in busy workshops or production lines. Its consistent performance also means less rework and more predictable results – key benefits when working with demanding clients or tight deadlines.”
Safety
“One of the most significant advantages of the EWC is safety. By eliminating pickling paste, the process removes exposure to toxic fumes and skin contact with hazardous substances. It also reduces the need for waste disposal associated with traditional chemical methods, making it a cleaner choice both environmentally and operationally.
“For businesses focused on productivity, worker safety, and long-term durability of stainless steel components, electrochemical weld cleaning represents a meaningful upgrade. The Pro Inox EWC is part of a shift toward smarter tools that streamline fabrication while aligning with modern health and environmental standards.”
The benefits and process of electrochemical weld cleaning
“Electrochemical weld cleaning is a process of cleaning away surface contamination and oxidisation caused by the welding process. The Pro Inox electrolytic weld cleaning machine cleans steel welds safely with maximum speed and efficiency. It eliminates toxic pickling paste and less efficient weld cleaning methods. Our cleaning fluids are safe and low-risk, containing mild electrolytes. A conductive carbon fibre brush and mild cleaning fluid achieve weld cleaning and passivating, leaving the surface with good corrosion resistance.”
“Always neutralise the metal surface after weld cleaning. Use a 3DI001 neutralising fluid to remove acidic residues and prevent white frosting. The process boosts corrosion resistance. Physically wiping with a cloth is important to remove the residue.”
“The unit has provision for two brush connections. The carbon brushes are consumable items and are easily replaceable. The small footprint makes the unit easily portable.”
“Another big benefit is the price of the local product. You can virtually purchase three of our machines for the price of one imported machine. Plus, servicing and spares are readily available.”
“Besides the corrosion resistance and durability of stainless steel, it is also aesthetically pleasing to the eye with its bright look. All the more reason that companies should strive to achieve welds that match the rest of the product. And it does not have to be because you are producing medical or food service products. All industrial products manufactured should have the same care taken during fabricating and assembly.”
“It’s like the old adage: The first impression is the lasting impression.”
