Figuring out how to weld, clean, and finish stainless steel can seem intimidating at first, but don’t get discouraged. Stainless Steel: MIG (Metal Inert Gas) welding. If you weld stainless once every six months or so, pickling paste is the best way to go. The electrochemical weld cleaning process doesn’t take a lot of time. Electrochemical cleaners are suitable for small shops that do stainless regularly but in low volume. There are two types of electrochemical cleaning that are used in welding. When a hairline finish must be restored, use an elastic flap disk to remove the weld. The most common among them are electrochemical cleaning, chemical pickling, mechanical grinding, and brushing. The welded metal piece is submerged in a mild electrolytic cleaning fluid. Q. To get a bright reflective finish, you will have to work up from 320 grit through finer grades until you are up to about 1500 grit. Use the application brush that comes with the paste or purchase an acid-resistant brush to apply it. This process is quite effective for cleaning steel after fabrication but welders don’t like it for a couple of reasons. It is dangerous, but no more so than welding or using a cutting torch. To get a true mirror finish, you will need to go through each of these steps. It’s attractive but not flashy. Another use of phosphoric acid is to give the tangy, sharp flavor to cola drinks. This can diminish the aesthetic look of their finished project and make it look amateurish. Electrochemical cleaning is easy to perform anywhere because the equipment is quite portable and easy to move around. Corrosion is a natural, oxidation process. When removing the paste, be as gentle as possible. An electric circuit is formed by passing current (AC/DC)) through the electrolytic solution. There is no reason to go to the expense of using stainless steel if you are going to let that happen. There are several methods to remove heat tint. A reflective finish is bright and shiny, but not actually a mirror. You need a polishing or buffing compound and a polishing wheel to get a full mirror finish. Another way to get a very high level of shine, similar to a mirror finish, is to use electropolishing equipment. It’s less critical to grind the bead down in internal corners. If you aren’t going to do a lot of inside corner grinding, you can use a flexible shaft on a rotary tool with the appropriate grinder wheel to get into nooks and crannies. The satin finish requires more work to get an even, bright tone that isn’t too reflective. We love them because of how they look and feel on our wrists. The top end of stainless-steel finishes is the bright mirror finish. Satin and matte finishes don’t have any direction to the marks. A sheet of stainless steel needs to be tack welded. If you choose to use acid baths, you need to provide a dedicated setup and follow safety precautions. Depending on the project, you may want to smooth out the bead or remove it entirely. This will remove the bead without removing too much of the metal underneath it. However, stainless steel can discolor after welding and lose both its good looks and its corrosion resistance. No. Apart from post-welding cleaning, the process is also quite effective for removing rust, cross-contamination and other kinds of impurities from metal surfaces. Second, only a certified operator is allowed to use chemical pickling paste. You should be aware of the necessary safety precautions if you are going to use it, though. Stainless steel has a reputation for being difficult to work with. However, it is still far from being completely rust-resistant. Both follow the same underlying principle of moving electricity through the weld to remove discoloration. It looks good and resists corrosion, but it won’t show fingerprints or smudges. This covers the surface with an iron-free chromium oxide layer and gives it the shine that stainless steel is famous for. For cosmetic purposes, it’s most important to get it flush on the top side where the joint can be seen and felt. The first involves a manual application of electrolytic liquids to the workpiece using a carbon brush. These cleaners won’t over- or under-clean the surface. Acid baths are best for high-volume environments, small parts, and low-profit margins. The process of electrolytic cleaning is extremely simple. 4 finish is the most common finish for architectural work. A few years ago I got really into welding as a side hustle. Hello, I'm Ben and I love learning about Welding. A wet cloth or sponge is the best way to remove the paste, followed by a gentle spray of water. If you’re set up for sandblasting auto bodies or other painted work, blast away. First, chemical pickling paste contains a variety of toxic acids, including hydrofluoric, nitric, and sulfur acids. When it gets scratched, the freshly exposed metal will react with the air to seal the scratch. Muller Media LLC is compensated for referring traffic and business to these companies. This finish looks clean with minimal upkeep. To create a matte finish without any grain to the metal, use a 320-grit grinder and work out all of the tool marks from the previous grinding. It involves using a chemical pickling paste for cleaning after a welding job. No. Unlike grinding, this cleaning method will successfully remove all dirt and discoloration from the welds. It worked but was too slow- transformer was only 60W output, more power and/or a commercial acid (citric or phosphoric) should correct that. I've had a quick play with lemon juice and a 12V halogen downlighter. It takes a while to reach this finish, so keep at it. It is faster, safer and preferred by welders, compared to the other two methods. See ASTM ASTM A380 [link is to the practice at TechStreet] . 6 are used for food manufacturing and restaurant equipment. The water rinsing the paste away can splash and cause acid burns. This layer separates the iron base underneath from interacting with moisture in the environment. Use paper or other protective coverings to protect stainless steel surfaces during and after fabrication. One issue is whether the heat tint discolouration in the heat-affected zone of stainless steel welds should be removed. Each has advantages and disadvantages. Welcome to weldingboss.com & drop a line when you get a chance! Citric acid can also be used to passivate stainless. You will need to wear eye protection and have gloves that will protect against the paste. In resistance welding, lower current can be used because resistivity is higher. Good electropolishing apparatus will clean and passivate a metal surface at the same time and you don’t need to carry out any repetitive tasks. The tool i use is a dremmel grinder,and i make my own sanding disks out When you clean the stainless steel surface after welding, you should also ensure that the surface layer is repaired. You are better off not grinding the stainless than using a contaminated grinder. After welding stabilized pieces, requirements of solution and stabilization heat treatments can be followed, but not always, because sometimes this procedure can be impossible or doubtful. The second method involves using special electrolytic baths where metal parts are immersed in electrolytic fluids. What is heat tint? Final Finishing Stainless Steel Welding Heat Marks, Cold-rolled, annealed, pickled, passivated, Cold-rolled, annealed, pickled, passivated, rolled through polished rollers, Smooth, dull, corrosion-resistant. These cleaners are sold at most home supply or hardware stores, and contain tiny abrasives that lightly scratch the surface of the stainless steel which removes the contaminants from the surface and leaves the metal shiny. I am a teacher living in the Pacific Northwest and an amateur welder. These cleaners are great for sculptors or making custom auto accessories. They are also useful for home welders who weld lots of stainless and are willing to invest in the equipment. One unique finish you can apply if you have sandblasting equipment is a bead-blasted finish. You should also bring a lunch – this finish takes a long time to achieve with a grinder. When stainless steel is commercially finished, these grades are specified in the product requirements. Electricity is moved through the metal which reacts with the electrolytic liquid and creates a uniform, clean surface. Most metals, including stainless steel, have an oxide layer at the surface. It is later removed and the surface is neutralized with a neutralizing agent. The operator’s whole body must be fully covered so that there is no chance of contact with the acids. If you use the same grinder wheels for stainless steel that you use for regular steels, you risk contaminating the stainless. Stainless steel is beautiful in any home, but care and attention are needed to keep it shining like new. Before addressing the heat tint, you may want to grind down the weld bead. Works on parts that can’t be dropped in a bath to soak or be cleaned electrochemically. No. Understanding a few simple tricks can help you minimize the frustration and save your work without having to start from scratch. One particularly unfortunate aspect of stainless steel is it's likely to display fingerprints. This is important for foodservice applications, but you can skip it if you are only concerned about appearance and not sanitation. Make sure you wear adequate protective equipment and neutralize the acid after the piece comes out of the acid. Pickling paste has a thick, gel-like texture. You must remove the discolored layer to finish the steel. The most significant difference in a brushed finish and a satin or matte finish is the direction of the brush marks. If you don’t have much use for a sandblasting setup but want to spend money on stainless steel finishing, you should probably look at electrochemical equipment instead. Straightening steel after welding can be a frustrating job. For hard to reach spots, check out a specialty grinder such as a fillet weld grinder, a horizontal-shaft grinder, or a die grinder. No. Pickling paste is the other good choice for weekend welders. They are expensive but safe and effective. It’s also useful for projects that will be polished to a high shine because you need to do lots of grinding anyway. 8 are similar finishes. link to Can You Use the Same Gas for Both MIG and TIG Welding? Welding is considered by many a technique and artform for enthusiasts and professionals alike. To avoid inhaling them, make sure the area is well ventilated. It also masks the after-effects of welding and hides surface damage, if any. The best way to clean stainless steel after welding is through a process called electropolishing. High temperatures. A clear face mask is also recommended. Begin with cool settings and gradually add heat if you need better penetration or a stronger weld. All these terms are talking about the same thing, a change in the color of the top layer of stainless steel. Most welders choose to work with stainless steel due to its better durability, maintainability, appearance, and higher resistance to corrosion. ), Works for large parts or built-in equipment, If you grind the bead off, you have already made a good start on this, May not result in a good passive finish to seal out corrosion, Hard to use with very small or intricate parts, Easier to get into tight corners than grinding, Many shops already have the equipment, especially auto body shops, Equipment is expensive if you don’t already have it, Like grinding, doesn’t always produce the passive finish that repels corrosion. This is especially important if you are going to be spraying the paste on or washing it off. Cleaning Stainless Steel After Welding By Dick Kostelnicek Home Metal Shop Club – August 2013 . You don’t need a respirator unless there is no way to vent the work area. 10. This makes electropolishing very safe, and it can be used by both DIY hobbyists and professionals. 8 is the finish you’d want in a mirror for shaving or applying makeup – it’s perfect. This site is owned and operated by Muller Media LLC. When this type of abrasive flap disk is used on a variable-speed angle grinder at a maximum of 8,000 RPM, the grinding te… You connect the electropolishing equipment, drop the steel in the tank, and walk away. Dirt on the surface of your stainless steel takes away its appealing shine. This is a process similar to electrochemical cleaning but configured slightly differently. Just go over the whole surface until everything looks the same. Each one has advantages and disadvantages. This finish can be a nice contrast to highly polished finishes. However, there is one downside to owning a stainless steel watch: it will look dull over time and wouldn’t look as perfect as how it once was. Shops that do lots of stainless work have large tubs of acid for soaking off heat tint. 5 is the minimum needed for food equipment, while No. This finish leaves everything looking consistently dull. This is why it is important to clean and polish your welding projects before and after the welding job. Before you apply pickling paste, be aware of the necessary safety precautions. There are several ways to remove this layer, including chemical baths, pickling pastes, electrochemical finishing, and manual grinding. You might also want to perform some more grinding and polishing to reduce the weld bead and to match the finish of the welded area to the rest of the surface. The chromium in the steel reacts with oxygen to form a thin layer of chromium oxide on the surface of the steel. Least expensive option for removing heat tint. That’s easier than running a grinder all day. How much safer? Plan a project, buy some stainless, and get to work – you’ll be surprised how easy it is to create stunning projects. Physical grinding is useful for occasional stainless projects, tight budgets, and pieces that won’t be exposed to the elements much, like indoor railings and counters. Here is a list of reasons you might want to remove the weld bead: Start by grinding the bead with an angle grinder using a flap wheel with 40, 60, or 80 grit. Methods to Remove Heat Tint From Stainless Steel, Acid Baths to Remove Stainless Steel Welding Heat Ting, Electrochemical Cleaners for Removing Heat Ting After Welding Stainless Steel. It won’t break the bank like a specialty grinder, and you’ll find lots of other uses for the rotary tool. The electrochemical cleaning process carries out surface passivation at the same time as cleaning which means you will effectively finish both processes at the same time. This process involves the oxidation of an acidic electrolyte on a metal surface with the help of electricity. A low cost yet highly productive method of welding, which can be used on all common metals and alloys. Welding equipment research suggests that the electrochemical process provides the best corrosion resistance compared to other cleaning methods due to its passivation effect. The best way to clean stainless steel after welding is through a process called electropolishing. Acid baths are a good solution for shops that crank out lots of stainless steel regularly and don’t spend a lot on cleaning. Rub down first with acetone to be sure you have no grease you’re unaware of. This practice is widely used by the automotive industry to blacken stainless steel parts, such as windscreen wipers, and it is used by manufacturers of stainless steel solar collection panels and trivets for domestic gas stoves. No. The resulting surface has a bright, beautiful finish – if you need a mirror finish, electrochemical cleaning is a good start, Electrochemical cleaning machines are expensive – new TIG welder expensive, Doesn’t work well for high-volume environments, May not work for large parts that can’t go in a bath, You already have the equipment. The grinder physically removes the top layer of metal that is heat tinted. Also known as Gas Metal Arc Welding (GMAW). Grinding is easy since you already have a grinder, but it takes a long time. Brushing is used to prepare the surface and remove particles after cleaning. I start using wet dry sand paper 150 gr.then 220 then 320,400,600,800 until I get to 1000 gr.,after i am done i use the polishing compounds. This helps preserve the surface, strength, and shape of steel structures. It can be all too easy to make some severe welding mistakes if the designer or welder aren’t aware of the specific requirements of the specific food application the steel wire basket or tray is going to be used for. The usual polishing methods (Autosolv etc) will give great results. There are several different levels of finish that require different abrasives and techniques. How to straighten steel after welding? Soaking the weld joint in a bath of nitric or hydrofluoric acid will remove the heat tint with ease. Whatever you use, work slowly along the weld bead until it has been ground flush with the metal on either side. These chemicals are quite dangerous for the human body and they can cause serious, long-term damage to the skin and internal organs if they are consumed or breathed in. Each of them offers various benefits for welders. If you aren’t dedicated to fabricating stuff from stainless, grinding and pickling paste are good options. There are a number of pastes which can be applied with a brush if the area to be treated is small. I'm Pierre Young. Unlike grinding, this cleaning method will successfully remove all dirt and discoloration from the welds. Using a sandblaster or other abrasive spray cleaner will remove heat tint as effectively as physical grinding. (See “Caution” below.) Electropolishing not only clears the surface from stains, but it also helps the metal become properly passivated. Heat absorbency is another characteristic of this material. The paste is applied to the affected areas using a brush or spray and left on the surface for some time to interact with the metal. Stainless steel can be welded with shielded metal arc welding (MIG), gas tungsten arc welding (TIG) and stick welding, and each of these processes will yield a slightly different result. Electrochemical weld cleaning is particularly effective for cleaning welds created with stainless steel. The fiber in the compound is derived from the hemp plant, which provides excellent abrasion while also being environmentally friendly. YESWELDER Large Viewing Screen 3.94"X3.66" True...

Use a stainless steel polish to remove stuck-on stains such as food, tar and surface scratches from the surface of stainless steel. Welding corrodes this chromium oxide layer and discolors the steel. Mechanical welding consumes a lot of time and rarely achieves 100% clean results with necessary aesthetic value. It won’t take long for your weld joint to look like a mess on an otherwise bright surface. Stainless steel is an alloy of iron, carbon, and chromium. Another way to remove heat tint is to grab your angle grinder or belt sander and get to work. Aggressive Conditions Cause Rust on Stainless Steel. One type of abrasive disk that does this is made from a compound developed specifically for grinding stainless steel. Just keep grinding until the heat tint is no more. Electroplating uses electricity to add a layer of bright metal on top of cheap base metal. Recent innovations in abrasives technology can reduce process steps to deliver the desired finish, including that sought-after surface shine. The passivated layer is self-healing, too. In some applications, one or both steps may be necessary. It is simple, inexpensive, and doesn’t take lots of work. But hold on. They don’t require much labor. I use a scotchpad on my 5" grinder but it creates semi-circle swirls which are hard to make uniform. Let the metal cool after welding – hot steel can cause faster reactions with the paste that release toxic fumes. When electricity passes through this mixture, it creates a chemical reaction that removes welding contamination or rust from the surface. Each has advantages and disadvantages. To remove the bead, grab an angle grinder, and get to work. 7 and No. The cleaning process uses phosphoric acid, which is much safer than acid baths or pickling paste. The chromium content may be increased and other alloying elements added or adjusted to meet specific end- use or manufacturing requirements. This process helps clear impurities from the weld, removing discoloration and creating a desired level of passivation. For projects involving stainless steel, this stage isn’t optional. Start-to-finish time with electropolishing isn’t faster than hand grinding and polishing; however, the labor requirements are much lower. Unlike most kinds of steel, stainless won’t rust or corrode when exposed to the elements. When welding stainless steel, always use low heat. It’s best to do this first because you want the process of cleaning the heat tint to clean the top layer that will remain. Is Pickling Paste A Good Way To Remove Weld Heat Marks From Stainless Steel? To retain the highest level of corrosion resistance, you must remove the heat tint layer and get back down to bright silvery steel. If you leave the heat tint alone, it will corrode faster than the rest of the metal. It only contains a mild phosphoric acid that you would also find in common soft drinks. While these colors may look pretty, they reduce the composition and oxidation properties of stainless steel. 5 and No. Disadvantages of electrochemical cleaning: Can I Remove Welding Heat Marks With Blast Cleaning? It’s important to know what these common finishes are and why they are important. To keep your stainless-steel project looking good for years to come, you need to do some finishing after you weld. To reshape steel that has suffered distortion during the welding process, welders use one of the following methods. Once the bead is in its final state, you can start working on the heat tint. These look nice, but if you want your stainless steel to look like stainless again, a polishing step is required. This process focuses on producing a consistent, smooth surface across all the stainless steel instead of removing heat tint. Mostly brushed dairy pipe. A less common form of rusting occurs after the stainless steel has been exposed to very high temperatures in the 750–1550°F range. The difference is in reflection quality. Keep grinding until you have a smooth surface, then start in on the heat tint. Stainless Steel For Welding Repair. If you continue to use this site we will assume that you are happy with it. You can perform manual electrochemical weld cleaning with the brush on site, off site and anywhere in between. Pickling paste is a material made from hydrofluoric and nitric acids, along with thickening agents. When stainless steel is heated to welding temperatures, it turns lots of pretty colors - gold, red, purple, blue - depending on the temperatures. Shops that do lots of stainless work have large tubs of acid for soaking off heat tint.
