What is a TIG Brush used for?
TIG Brush® is designed to rapidly remove the discoloured oxides that high welding temperatures cause, without altering the look and finish of the metal. Engineering Utilities specialises in supplying equipment and consumables for metal preparation, finishing and cleaning.
Why do you need to passivate stainless steel after welding?
Without passivation, contaminants in the environment (such as chlorides) can react with free iron on the surface of the metal and start the corrosion process, which will extend into the component via the weld. Passivation is carried out to slow down or eliminate this process in two ways.
How do you clean stainless steel after TIG welding?
The best way to clean stainless steel after welding is through a process called electropolishing. This process involves the oxidation of an acidic electrolyte on a metal surface with the help of electricity.
How do you clean a TIG welder?
The electrolytic weld cleaning process is simple, fast, and effective. Using a conductive weld cleaning brush, a mild electrolytic cleaning fluid is applied to the welded joint or surface of the metal. Electric current is used to accelerate the cleaning and passivation process.
Why do you brush a weld?
Wire brushes are a staple for weld cleaning. They’re versatile and effective tools for removing surface contamination, such as rust or heat discoloration, without removing base material.
What is electrochemical cleaning?
Electrochemical cleaning cleans metal after mechanical processing (including welding). The metal workpiece is immersed in an electrochemical bath typically filled with an acidic electrolytic solution.
What happens if you don’t passivate stainless steel?
Passivation cannot make problems associ- ated with lack of a suitable welding purge go away, i.e. severe weld discoloration or sugared welds. Cutting, grinding and mechanical polishing also alters the stainless steel surface and can affect the passive surface.
How do you remove discoloration from stainless steel after welding?
Several methods are commonly used to remove discoloration on stainless steel after welding.
- Electrochemical cleaning.
- Chemical pickling.
- mechanical grinding & wire brushing (are just a few of them)
How do you remove blue from stainless steel?
The good news about this new color on your stainless steel is that it is easy to get rid of. If you are looking for an inexpensive way to clean the surface, then look no further than regular white vinegar. Dilute some vinegar in water and use a nonabrasive cloth or sponge to rub down the surface that has been affected.
How do you remove oxidation from welding?
Why do you have to brush welds?
The process cleans up rust, heat discoloration (including burns), and cross-contamination while also passivating the steel to prevent future corrosion.
Which metals can be passivated?
Chromate conversion is a common way of passivating not only aluminium, but also zinc, cadmium, copper, silver, magnesium, and tin alloys. Anodizing is an electrolytic process that forms a thicker oxide layer. The anodic coating consists of hydrated aluminium oxide and is considered resistant to corrosion and abrasion.
Does passivation remove weld discoloration?
Weld Discoloration Removal Passivation of these areas is key to restoring the corrosion resistance, and this can be done with or without the prior removal of the discoloration, oftentimes using CitriSurf 2210.
What causes rainbow on stainless steel?
Turns out those vibrant swirls are widely known as “heat tints.” By design, stainless steel contains a touch of chromium (a very sturdy metal that helps protect your pans from corrosion and rusting), When chromium and air mingle, a protective layer appears on your pan—a protective layer that happens to be very thin.
How do you clean TIG welding steel?
Use an angle grinder with a 60- or 80-grit flap disc and grind off the mill scale until you get down to bright, shiny metal. You don’t need to clean off the entire bar, though – just clean the joints where you’re going to weld. Then use a rag and wipe the metal down with acetone to remove any remaining grease or oils.
How do you use a TIG brush?
HEAR HOW THE TIG BRUSH WORKS FOR YOU… We’ve transformed the weld cleaning process into 3 simple steps that work for you. Dip the brush into one of the cleaning fluids available in our range. Make contact with the weld, move slowly across in a circular motion (Re-dip if brush dries) and rinse the area with water.
Why choose Tig brush Weld passivation?

What type of cleaning fluid is used in the TIG brush?
Weld cleaning fluids are used during the TIG Brush electrochemical weld cleaning process. The fluid is designed to be safe at room temperature, but aggressively remove the heat-tint found on stainless steel welds after TIG and MIG welding.
Why use a TIG brush to clean stainless steel?
