Food Grade Welding Incorporates Cleaning and Disinfecting in the Process

It’s no secret that food-grade welding is one of the more temperamental welding processes, thanks to its high standards and requirements. But it’s also undeniable that those standards have a purpose and cannot be skirted for the sake of convenience. Northland Fastening Systems (NFS) provides the tools and equipment you need for high-precision sanitary welding, and encourages all welders to take food safety seriously for large and small welding projects alike.

Keeping a Clean Workspace

While careful cleaning isn’t usually what prospective welders’ picture when they’re prepping for a job, when it comes to food-grade welding, cleanliness does matter. The best materials in the world can’t compensate for dirty tools and environments, which means that, as the welder, you need to ensure that your welding process is as contamination free as possible. This doesn’t necessarily mean spraying down your surface after every weld, but it does mean that an effort should be made to prevent unnecessary mess. The good news is that quality sanitary welding is well suited to easy cleaning.

Food Grade Welding

Sanitary welding is all about preventing gaps, crevices, and cracks that can allow moisture and germs to fester. Rough surfaces and faults can be deadly for sanitary welding, which means that thoughtless and haphazard welds won’t cut it. In general, haphazard welding won’t look good on a job, but in food-grade welding any irregular surface can be a breeding ground for germs. In some cases, this may mean sanding or filing edges until they lay flat and even. Once sanitary welding is complete, you should be able to easily disinfect the surface without encountering hard-to-reach areas.

Food-grade welding might be a high-effort process, but the results produce vital equipment for a huge variety of health- and safety-related industries. The high standards they require are also a great lesson for all types of welding. Even if the weld you’re working on isn’t necessarily food grade, preventing sharp edges, cracks, crevices, and faults should always be the goal. It’s also great to get into the habit of keeping your work area clean and your surfaces disinfected. Whether your welds are going to end up in a garage or a hospital, practicing the tenets of sanitary welding will boost the quality of everything you make.

Food-Grade Welding with Sanitary Practices

Ensuring that your fabrications satisfy the requirements of food-grade welding is as much a matter of quality welding as it is a matter of safety. Food-grade welding is, understandably, an incredibly strict area of production. While all welding comes with a level of risk, sanitary welding, when done improperly, has the potential to make a lot of people very ill. At Northland Fastening Systems (NFS), we take safety seriously and can help you find the tools, techniques, and materials you need to create truly safe machinery with food-grade welding.

Food-Grade Welding Designs

No matter how skilled or precise your welding may be, if a planned design is poorly suited for sanitation, there’s a good chance the final product will never be approved for food-grade production. Understanding the type of designs that lend themselves to food-grade welding is the first step to creating safe and consistent fabrications.

A key aspect of sanitary welding design is ensuring that no fastening or part of the machine has the potential to catch or trap food debris. Designs featuring many sharp angles, divots, or nooks and crannies can become a hotbed of bacterial growth that can quickly lead to illness. This is true in every type of food-grade fabrication from single machines intended for school use to wide-scale factory conveyors. In fact, every step of food-grade welding must be checked and double checked to ensure that it lives up to the strict requirements by the U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA).

Welding Materials

And similarly, a perfectly designed machine will never be a sanitary weld without the correct materials. Porous materials or materials that are prone to corrosion can become health hazards when placed in a food-oriented environment. Sanitary welding materials such as stainless steel are well suited to such projects, but in order to ensure that they stay safe, materials must have a smooth surface and zero risk of flaking and coming into contact with food.

A combination of highly skilled welding and high-quality materials can facilitate such fabrications, and NFS can assist with both. If you’re working on food-grade welding projects and are in need of high-quality materials, tools, and support, we’ve got your back. Keep your food safe and your machines sanitary by calling us today at (651) 730-7770 or visiting our website for more information.


Food Grade Welding Has Steep Standards

Precision is the name of the game when it comes to sanitary welding. Every single bond needs to take the potential for contamination into account, and that means smooth, ridgeless surfaces, and clean connections with zero room for error. Northland Fastening Systems (NFS) provides high-quality, precise tools that allow welders to create safe and long-lasting food-grade welding products. With our expertise, we can help support new welders looking into reaching the incredibly steep standards that sanitary welding demands.

Food Grade Welding

Working with food grade welding means that you’re holding lives in your hand with every weld. Whether the products you’re manufacturing are going into school stoves, biopharmaceutical tools, or surgical instruments, you have to be able to guarantee quality and cleanliness every time. Any error in the weld could lead to a buildup of bacteria or other byproducts that could, in turn, result in injury or illness. In order to prevent this error from happening, your job as a sanitary welder is to stay on top of potential failure points throughout the food-grade welding process.

Installation of Piping in Sanitary Welding

A common application of food grade welding is the installation of piping. Piping represents the perfect sample size of everything you’ll need to master throughout the sanitary-welding process. Preventing burrs, ensuring smooth steel bonds, and implementing regular checks to prevent irregularities are all part of the complete piping package. A steady hand will only do so much. The secret of meeting sanitary-welding standards is checking, double-checking, and even triple-checking your work from piping and beyond.

Checks in Food Grade Welding

Comprehensive checks in welding start at the top of the process and must continue deliberately until the final bond is in place. Verifying weld parameters such as speed, equipment condition, and voltage should be done intentionally before any formal welds are completed. Even with decades of experience, triple-checking for potential faults is too important to overlook when manufacturing sanitary parts or machines.

If you’re looking for high-precision welding tools that you can trust to live up to food-grade welding’s rigid requirements, look no farther than NFS. Our welding equipment is reliable and accessible to welders of all levels. The road to high-quality sanitary welding may be steep, but with the right gear on your side you, can be prepared to start the climb today.

Application of Stainless Steel and Studs for Food-Grade Welding

Over the last 100 years, huge leaps have been made in the global food supply chain and the protection of food safety. The first federal regulations that began our national food safety journey started as early as 1906 with the Federal Meat Inspection Act. Later, the Poultry Products Inspection Act of 1957, the Egg Products Inspection Act of 1970, and several other hallmark legal changes were made to our food supply system. In more recent years, the Federal Food Safety Modernization Act of 2011 began to shift the focus of the Food and Drug Administration (FDA) from reacting to events of foodborne illness to instead working actively to prevent those occurrences. There are many ways our food industry can work to reduce, and eventually eliminate, outbreaks of foodborne illnesses, including in the design and construction of food-grade equipment. Food service equipment from the factory floor to commercial kitchens can all see vast improvements to hygiene when they are built with stainless steel and stud welding operations. Stud welding is one of the most sanitary manufacturing operations when it comes to food safe assemblies. If you’re working with food-grade welding for any type of service equipment, Northland Fastening Systems (NFS) has the supplies and tools you need to get the job done. We provide a comprehensive selection of welding studs, accessories, tools for rent and purchase, and the expertise of our own welding technicians.

Food-Grade Welding

There are many aspects to food-grade manufacturing, including eliminating the risk of harborage by removing nooks and crannies, building in full washdown capabilities for sanitation, utilizing anti-microbial materials, and sealing all connection points.

Building with stud welding and stainless steel goes a long way in establishing food service and industrial food processing equipment as “food quality.” Both stainless steel and the use of studs as fasteners are significant components of food-grade welding under FDA and NSF/ANSI regulations.

FDA and NSF/ANSI Compliant

Both the FDA and NSF/ANSI work to regulate different sections of the food industry to support safety and quality. This ranges from daily practices of manufacturers to the sourcing and distribution of materials.

1. Fasteners: All types of fasteners for food equipment should meet strict FDA and NSF/ANSI specifications. Fasteners must be made from noncorrosive materials that can seal, rather than bolt, framework. Because of this, studs are an ideal fastening system for food-grade equipment. Not only does it seal a surface permanently, it can also be installed with access to only one side of a work surface and result in a clean, low profile connection.

2. Materials: Studs can readily be used to connect frameworks made from stainless steel parts, sheeting, and other components. Stainless steel is fortified against corrosion and can offer a highly sanitary, low-microbe work surface for food preparation.

Building Complex Sanitary Conveyor Systems with Food Grade Welding

The global food industry is one of the largest economic systems in the world. Its success relies on intricate webs of distribution lines. With a world population of almost 8 billion people, the demands on the food industry to support access to everything from safe, nutritious foods to international delicacies are immense. When it comes to the industrial equipment used throughout the food industry, reliability and hygiene are some of the most important factors that engineers and fabricators should build into any design. For many kinds of automated food production equipment used in factory settings, stud welding provides strong, clean fastening systems without risk of harborage or corrosion. If you are working with food grade welding studs to build your food production equipment designs, Northland Fastening Systems has the tools and supplies you need. We provide a complete range of welding tools, studs, and accessories, as well as repair services and the advice of our own welding technicians.

Food Production Equipment

There are many different purposes that various types of food production equipment serve. One of the most essential systems in an automated facility is the conveyor belt operations. To prevent the risk of contamination in the complex parts of a conveyor belt, food grade welding with stainless-steel studs is used to build many components on an automated production line.

Conveyor Belt Systems

Conveyor belt systems meet a wide range of automated food production needs. In the process of moving goods from one operation to the next, most facilities need to maintain precise control over the product quality and load. Some aspects of a conveyor system built with sanitary stud welding include:

Laning and sorting:

Products moving downstream from operation to operation need to be accurately sorted into lanes or sections of a conveyor system. This keeps the production line running smoothly and prevents cross contamination, damage, or unnecessary loss of goods.


In many parts of processing in the food industry, products need to be handled in multiples. For the packaging industry in particular, food items often need to be stacked on top of each other while they move seamlessly through a factory. With sanitary automated stackers, production lines can reduce human error and contamination.


Like sorting systems, transfers also need to occur as products are moved on a conveyor system between different stages. Transfers built into an automated conveyor system keep the process running quickly through lateral or multi-level moves.


Most factories today are incorporating intelligent rejection systems to remove damaged or misshapen goods. These reject systems use laser measurements, weight, imaging, and other smart technologies to determine if goods meet the correct specifications and remove flawed products from the production line. With a reject system on a conveyor, automation can continue through that stage of processing.

Food grade welding contributes to the sanitation and quality of many operations that can be incorporated into a conveyor belt system and an automated production line in general. To learn more, contact Northland Fastening Systems today at (651) 730-7770 or request a quote online.


Building Stainless Steel Furniture with Food Grade Welding

One of the reasons why stud welding is such a prolific manufacturing operation is its versatility. Stud welding can be used to form powerful fastening systems for a variety of materials, including composite construction for bridges and other important infrastructure. Composite construction combines concrete and steel into a strong material that can resist enormous amounts of shear force, weight, and tension. Without the shear connectors and deformed bar anchors used in composite construction, we wouldn’t have the roads, bridges, multi-story buildings, and other large-scale structures that are key components of our modern world. The use of stud welding in composite construction is just the tip of the iceberg. Stud fastening systems are utilized across industries for anything from sheet metal construction to sanitary fabrication with food grade welding. No matter what industry you work in, you can find all you need for tools, supplies, and support with Northland Fastening Systems. NFS provides quality stud welding tools for rent or purchase, drawn arc, CD, and short cycle weld studs in a complete range of dimensions, custom stud options, welding accessories, and a repair program.

Food grade Welding

Stainless steel is a primary material used in food grade welding for many reasons, but, as a unique set of metal alloys, it can also be used for many other purposes when it comes to building furniture. Using stainless steel to construct various types of furniture with stud welding has many benefits. From aesthetics to practical purposes, manufacturers, artists, designers, and furniture companies build with stainless steel and stud welding to take advantage of their properties.


For food service equipment, commercial and residential kitchen appliances, and other instances where good sanitation and hygiene are critical, stainless steel is a remarkable material. Because stainless steel has antiseptic properties and is highly cleanable, it pairs well with the smooth, crevice-free results that stud welding can achieve to build sanitary furniture and food grade equipment.


Stainless steel also has corrosion resistant properties. The chromium content in stainless-steel alloys creates a passive film on the material’s surface. The presence of oxygen allows this film to self-heal when abrasions, cuts, and other damage occur. This means furniture made with stainless steel and stud welding operations can withstand corrosive environments and last longer than other metals.


With its sanitary and anti-rust properties, stainless steel is already a practical material for building furniture of all kinds. Its durability, strength, and flexibility only add to its value as a furniture building material. Compared to many other materials used to build furniture, stainless steel is one of the strongest and most practical.


For design purposes, stainless steel offers a great range of finishes, from the lustrous sheen of a polished, bare surface to the vibrancy and color ranges that annealing, plating, and other finishing treatments can yield.

Food Grade Welding Eliminates Harborage

Not only is stud welding a key operation for the construction industry, including composite construction with shear connectors in bridges, roads, and other infrastructure, it’s also utilized on smaller manufacturing scales for equipment like electrical enclosures, food grade instruments, and commercial kitchen appliances. In the food industry, stud welding serves an important purpose when it comes to manufacturing factory processing systems and equipment. Because stud welding creates clean results and strong welds without marking through on the reverse surface, it can be used to build smooth surfaces with full wash-down capabilities. If you’re working with food grade welding for the production of food industry or commercial food equipment, Northland Fastening Systems has the supplies you need for drawn arc, capacitor discharge (CD), and short cycle welding. We provide tools for rent and purchase, studs in a complete range of dimensions with custom options available, welding accessories, automation support, the advice of our own skilled technicians, and services and repairs for most models.

Food Grade Welding Makes Equipment Easier to Clean

Food grade welding with studs makes equipment easier to clean, helping commercial kitchens and food production facilities maintain sanitation practices and support good hygiene. Food products made on an industrial scale can be one of the main sources of foodborne illness epidemics. To eliminate the risk of food contamination, stud welding reduces the potential of harborage.

What is Harborage?

In the food industry, harborage occurs when particles are trapped in crevices, bends, and other hard-to-clean nooks and crannies in equipment. Not only does this introduce rotting or pathogenic food particles that can damage the integrity of other products; it can also increase the risk of rodents and insects in a facility. Stud welding reduces harborage by removing the crevices potentially left by other types of fastening systems.

Connection Points are Clean

Stud welding connection points are clean, smooth, and fully fused. Food grade stud welding processes also use antiseptic stainless-steel surfaces that resist corrosion or oxidation. With most designs, stud welding engineering can also reduce external angles and corners, eliminate risks of overstressed surfaces, and fully seal connection points from microscopic pitting.

Where Can Harborage Occur?

Harborage can occur in equipment that is not manufactured to the highest food safety standards in several areas, including control panels, equipment legs, cracks, crevices, hardware, moving parts, HVAC equipment, multiple surface types, and any wet areas. To fully remove problems with harborage in these areas, stud welding systems should be installed whenever possible.

Full Wash Down

With a tight connection point and no crevices, zero marks on the opposite side of the weld surface, low-stress surfaces, and corrosion-resistant materials that are compatible with full wash down capabilities, food grade welding can significantly reduce the risk of harborage in industrial processing and commercial kitchens.

The History and Role of the American Welding Society for Fastening Systems

While the origin of forge welding can be traced all the way back to the Bronze Age, the history of welding with electrical current only dates back to the early twentieth century. The first resistance welding technology was used extensively in manufacturing military equipment and vehicles for World War I. To establish the importance of the resistance welding industry even after the war ended, former President Wilson appointed Comfort A. Adams, an electrical engineering professor at Harvard College, as chair of the new Welding Committee of the Emergency Fleet Corp. Since then, the committee combined with the National Welding Council to become today’s American Welding Society (AWS). As a provider of stud welding supplies, including tools for rent or purchase, studs in a complete range of dimensions, and welding accessories, Northland Fastening Systems (NFS) follows the standards that the AWS sets for the industry.

High-Quality Stud Welding Equipment

NFS is a comprehensive supplier of high-quality stud welding equipment, and our selection of tools, studs, and accessories, along with our services, meet international standards for operations. In addition to our own standards for quality, original equipment manufacturers (OEMs) and all our other customers follow AWS regulations, and many hold specific AWS certifications.

Since its establishment in 1919, the AWS has been pivotal in advancing and expanding national fastening systems and welding industries in many ways.

A Brief History

After the Welding Committee of the Emergency Fleet Corp and the National Welding Council combined to create the AWS in 1919, the society brought together industry leaders. In its first year of operations, the AWS increased to 217 members and introduced the Journal of the American Welding Society. Although this journal only published one issue, it preceded today’s Welding Journal. The AWS also moved into its new headquarters at the Engineering Societies Building in New York City.

In 1922, the AWS held its first annual meeting, and by then, had established sections in eight major cities. For the next 49 years, the AWS headquartered in New York City, but in 1971, moved to Miami, FL, and then in 2012, moved again to its current location in Doral, FL.

Role of the AWS

In addition to the monthly publication of the Welding Journal, the AWS also offers multiple certification programs, including endorsement certificates, testing facilities accreditation, and fabricator certifications. Certifications include specific programs for welding inspectors, educators, radiographic interpreters, engineers, welders, sales representatives, robotic arc welding, and supervisors.

The AWS also has a membership program and publishes specifications and codes for the industry. Membership is available for individuals, welders, corporations, and students. Currently, the AWS has 250 international sections and student chapters.

As a member of the welding industry, NFS values the history and current global role of the AWS. To learn more about our stud welding equipment, products, and services, contact us by calling (507) 387-7200 or online.

Understanding the Sanitary Properties of Effective Food-Grade Welding

Using stud-welding operations for fabrication in many industries provides several benefits to manufacturers. Not only is stud welding a quick fastening process that results in a powerful connection point, it also provides clean results without marking the other side of the weld surface or creating rough finishes. Stud welding is useful to many manufacturers working in large-scale construction, heavy-duty composite building, thin pin installation, and even food equipment production. For food equipment, in particular, capacitor discharge (CD) stud welding supports sanitation regulations and hygiene standards for the food production, packaging, and processing industries. If you’re using studs for food-grade welding operations, Northland Fastening Systems (NFS) has the supplies you need. We provide a broad range of tools for rent or purchase, studs in a complete range of dimensions with custom options available, and a full selection of stud welding accessories. Our team of expert welding technicians can also provide advice and information, and our tool repair services eliminate excess production downtime.


Via the Food Safety Modernization Act (FSMA), the Food and Drug Administration (FDA) established many guidelines and requirements for every player in the food industry, from farms to food equipment manufacturers. Rules for food-grade welding were also outlined in this act. These rules set specific requirements for finished surfaces, connection points, materials, and all other aspects of manufactured food equipment.


Some basic requirements the FSMA sets for stud-welded food service equipment include:


  1. Sharps and burrs should be eliminated to prevent microscopic cavities that can house bacteria. When stud welds are performed correctly, there is no risk of micro burrs or sharps around the connection point. Too hot or too cold welds can, respectively, leave molten splatter and burrs, or create a slight ledge underneath the stud.
  2. Materials that are too dissimilar should not be used. While multiple kinds of materials can be welded together in other applications of stud welding, food-grade products should typically be limited to stainless steel or other treated metals that will hold up to corrosion.
  3. Internal corners and angles should be radiused. The FDA requires fabricators to manufacture designs that only use internal angles and corners so that exterior angles are softened and easy to fully sanitize. Sharper angles create crevices for bacteria and other cross-contamination to hide and be difficult to reach even when equipment is fully washed down.
  4. Surfaces should be manufactured without overstressing. When welding is not performed correctly, material surfaces can be overstressed, leading to corrosion, cracking, reduction of protective surfaces, and many other problems that compromise food safety. Accurately applied welds will protect food safety and prevent cross-contamination in the long term.


In addition to these requirements, stud welding also makes it possible for manufacturers to support the rule that frameworks should always be sealed and never bolted.
