Breaking Down the Process of Quality CD Stud Welding

Northland Fastening Systems provides high-quality stud welding services, stud welding tools for sale and rent, and every stud welding accessory you need to get the job done. From food-grade welding to structure-strength sheet metal welding using both drawn arc and capacitor discharge (CD) welding, NFS has the right equipment for the job.


Because stud welding is such an efficient, effective, and powerful tool in a wide range of industries, it’s one of the most critical operations in many fabrication projects. Both drawn arc stud welding and CD stud welding have a foundational use in different types of welding projects, but more and more technicians are utilizing state-of-the-art CD welding units for rapid welding purposes.


CD stud welding is, for all intents and purposes, a form of arc welding. In comparison to drawn arc stud welding, however, it’s much faster, performing a pre-calibrated weld in milliseconds that leaves little-to-no mark on the opposite side of the weld surface.


CD Stud Welding Step by Step

With the right tools, performing CD stud welding is a straightforward process for welders of all skill levels. Most CD welding units offer pre-programmed settings for a weld cycle, or simplistic ways of calibrating a preset voltage depending on the stud materials and size as well as the material of the weld surface. The process goes as follows:


  1. The stud welding unit is calibrated to suit the situation.
  2. A stud is loaded onto the gun tip.
  3. The stud welding gun is positioned at the desired weld point.
  4. The welding operation is triggered, sending energy stored in the capacitors to be discharged onto the stud in a semi-automatic arc.
  5. The heat of this energy essentially vaporizes the tip of the stud and creates an ionization path.
  6. The path opens up a full flow of current arcing across the stud and melting the metal of the stud tip.
  7. Pressure from the welder then forces the molten tip of the stud onto the weld surface.
  8. This pressure and the cooling metal forms a strong bond between the stud and the weld surface.


CD stud welding doesn’t use a ferrule like its cousin, drawn arc stud welding. This means the weld is performed much more quickly, but the nature of the weld limits the size of the stud. CD welding is suited to stud diameters from 14 gauge up to 3/8”, there are no limitations on stud length. Materials that can be welded using CD stud units include stainless steel, mild steel, brass, and aluminum. Although CD stud welding is not the best choice for heavy-duty purposes, it has a prevalent use in smaller scale, rapid, efficient production. Its weld connection is stronger than the stud material itself, and it can be more easily automated than other types of welding.

Understanding the Process and Benefits of Short Cycle Stud Welding

The various types of stud welding can be utilized in a broad range of manufacturing applications, and they cover quite a comprehensive amount of parts and components. From electrical enclosures and small-scale food industry equipment to construction equipment and sheet metal manufacturing, stud welding has an essential production use. When you partner with Northland Fastening Systems, you have access to our complete stud welding services as well as the tools, equipment, and accessories we provide. For both drawn arc stud welding and CD stud welding, you can trust NFS to meet all your needs with quality service and products.


When it comes to differentiating and understanding the types of stud welding we provide services and equipment for, there are a few points to take into consideration:


  1. Drawn arc stud welding utilizes a different welding process than CD stud welding. Learn more about the differences from this NFS blog post.
  2. CD stud welding is often more suited for welding thinner materials without leaving a mark on the reverse side of the weld spot.
  3. Drawn arc stud welding is more suited to welding heavier materials with wider weld spots allowing structural strength.
  4. CD welding is faster and requires less energy than drawn arc stud welding.
  5. Drawn arc welding is stronger than CD stud welding, and it can be used in large-scale construction applications.


NFS offers studs and other accessories for all types of stud welding including a variant of drawn arc stud welding called short cycle welding. Short cycle welding is a kind of drawn arc stud welding that can be performed faster than the standard process and is somewhat of a compromise between drawn arc and CD stud welding.


Here’s how it works:


Unlike typical drawn arc stud welding, short cycle welding does not use a ceramic ferrule to contain the molten metal at the weld point. Short cycle welding is performed by creating a pilot arc that melts the end of the stud and then connects the stud to the base material using pressure between the base and stud alone. This weld occurs in 10-100 milliseconds and can use CD studs depending on the welding circumstances. Basic necessities for the application of short cycle welding include:


  1. Three-phase and 480-volt power supply
  2. Threaded CD studs like those offered in the NFS store
  3. A base material thicker than 1.7 mm at minimum


The benefits of short cycle stud welding are many when used in the correct application. Short cycle welding is faster, uses lower-cost equipment, provides a higher tolerance weld point on irregular or coated base materials, and is often more convenient than typical drawn arc or CD stud welding. Short cycle stud welding is also more easily automated than other stud welding operations.

Why Food-Grade Welding is Widespread Throughout the Common Commercial Kitchen

From restaurants to hospitals to food trucks and beyond, every commercial kitchen utilizes a wide range of stainless-steel products. Because stainless steel is highly resistant to corrosion, acid damage, and other concentrated substances that often show up in kitchens, it’s the most logical choice of material for many components in commercial settings. The production of these stainless-steel kitchen products is most efficiently completed with stud welding processes. At Northland Fastening Systems, food-grade welding capabilities are just a click away with our stud welding services, tool rentals, and available equipment and accessories.


The efficiency and practicality of stud welding stainless steel for food-grade welding products is the primary reason why the demand for such a wide range of these kitchen components is so prevalent. Many other materials will rust, allow mold growth, start to degrade, and otherwise pose unhealthy working conditions and food production sanitation.


With the rapid welding process and strong connection points stud welding gives manufacturers of food-grade products, it’s not uncommon to see a variety of kitchen components in a commercial setting including:


  1. Stove units made with stud welded stainless-steel sheeting that holds up to the flames, grease, and other stresses in a commercial kitchen.
  2. Stainless-steel cased ovens that hold up to constant heat throughout the day and long-term use of that daily capacity.
  3. Shelving units that must support up to 2,000 lbs. regularly while exposed to temperatures ranging from walk-in freezers to heat from adjacent stoves and ovens, in addition to grease and moisture exposure.
  4. Tables and counters that hold up against continual exposure to acidic foods and liquids, knives, abrasive cleaning fluids, pounding, heavy weights, grease, heat, and cold.
  5. Heavy-duty kitchen ventilation systems and stove hoods that filter out highly acidic smoke, heavy-duty grease, and moisture constantly throughout the working day while often withstanding high heat from stovetops.
  6. Sinks and plumbing systems that take on grease, food, hair, dirt, and more in the day-to-day business of a commercial kitchen.
  7. Coolers and refrigerators that are subjected to constant opening and closing, food spills, moisture collection, freezing water, and abrasive cleaning.
  8. Commercial dishwasher units that are continually exposed to water at high sanitary temperatures, grease, acidic foods, and harsh chemical soaps.


In addition to these common systems, there are many more components of a standard commercial kitchen made with stud welded stainless steel, including some more specialized products involved in food production (such as the beer and wine making processes) that are designed to hold up to severe daily conditions.


With the use of quality stainless steel and well-made stud welding studs like those offered at Northland Fastening Systems, you can create your own commercial kitchen components that hold up to harsh environments. Contact us at (651) 730-7770 to learn more about food-grade welding and the equipment and services we provide.

Using the Right Welding Studs for the Right Project

Stud welding is a highly effective process for forming strong connection points quickly and with a clean finish. However effective stud welding is, it’s not as effective as it could be if you’re using the wrong welding studs. There are several types of welding processes that require different studs, and understanding which studs are best for the weld gun, welding unit, and material you want to weld is key to successful production. Northland Fastening Systems provides a wide range of welding studs suitable for any project you need to complete.


From drawn arc stud welding to capacitor discharge stud welding, NFS offers welding services in addition to tools (available for rental and purchase), and of course, welding studs. No matter what format you need to fit your studs in, you can find what you’re looking for with NFS.


Common Welding Studs


Some of the most common welding studs that NFS offers that are suitable for a range of stud welding projects include:


  1. Flanged CD Studs: Made from stainless steel, aluminum, brass, or low carbon steel, flanged studs range in stud and flange diameter, thread, and length. Flanged studs can be annealed for durability and strength and plated in copper for heightened electrical conductivity.
  2. Non-Flanged CD Studs: Similar to flanged, non-flanged CD welding studs can be made from the same materials with the same annealing or plating processes. The difference lies in the size of the top of the stud. For a clean weld in applications where a flange would interfere with the materials being connected (often stud welding production with sheet metal), non-flanged studs are highly effective.
  3. Threaded Arc Studs: Both fully or partially threaded arc welding studs are made from mild steel or stainless steel and can be of varying thread size, length, and stud diameter. These studs can be used in applications where a peg stud has to protrude from the weld point (partial thread) or fully welded into a material (full thread).
  4. Anchor Arc Studs: Varying in stud length and diameter, anchor arc welding studs are made from low carbon steel or stainless steel. They are useful in forming peg studs of various lengths protruding from the weld point that offers a reliable, strong weight capacity.
  5. Bar Anchor Studs: Made from low carbon steel and available in a range of diameters and lengths, bar anchor studs are key in load-bearing production and provide a highly durable connection point.
  6. CD Welding Pins: Thin CD welding pins are made from mild steel and often have a copper plating to support conductivity. They create a nail-like point for lightweight support and connection useful in many building interior installation projects like, for example, installing insulation.


In addition to our range of welding studs, we offer quality goods and services in a pinch. Contact Northland Fastening Systems at (651) 730-7770 to learn more about our stud welding services and equipment.

Importance of Shear Connectors in Construction Welding

As engineering advances, new materials are introduced, new equipment is developed, and the world’s capabilities for building and structural construction are changing rapidly. New and improved methods for building taller, stronger, and better buildings are tested and implemented every year. One construction technology that continues to prove effective in both cost and performance is the use of shear connectors as reinforcement for several building components. Northland Fastening Systems provides stud construction welding services, equipment, and tools for many types of construction projects, including shear connectors in varying sizes and forms.


While some shear connectors are not installed with stud welding techniques, there are types of shear connectors that are highly-effective when joined to a connection point using a stud welder.


Stud Welded Shear Connectors


  • Shear Connectors: NFS provides a type of shear connector that’s the most commonly used across the world in building construction. Offered in varying sizes, these shear connectors are used in concrete-to-beam connections and reinforce that joining with a resistance to shear load stresses. The shear connector is welded to a steel beam and fixed through a concrete slab with additional steel plates supporting the flexibility and strength of the slab.
  • Headed Studs: The headed anchor weld studs we offer in several sizes are a perfect example of a variation of the common type of shear connector. These studs have a wide base that provides a larger weld point to steel beams or girders and can be used in most concrete-to-beam construction projects.


Construction Welding Applications of Shear Connectors


Shear connectors are a critical way of creating strong connection points that hold up to shear loading. They are used in many applications including, but not limited to:


  1. Connecting upright steel beams to a concrete foundation
  2. Connecting load bearing beams to a concrete flooring in multi-story buildings
  3. Connecting composite slabs to steel beams in overpasses and other small to large scale bridges
  4. Reinforcing roads and sidewalks and preventing excessive freezing damage
  5. Connecting steel decking to concrete or composite ship floors
  6. Connecting metal roofing to interior ceiling materials


There are hundreds of applications of shear connectors in building and structural construction. This is because they are a vital piece of engineering that provides a powerful connection point between two materials that are difficult to connect otherwise. If you’re embarking on a construction project that requires the use of shear connectors, Northland Fastening Systems has the equipment and accessories you need.

Building Bridges Safer and Stronger with Construction Stud Welding

Stud welding is a unique welding operation because it has such a broad range of applications varying in several ways including the size, strength, and function of the weld and stud and the materials used. However, stud welding is often considered the lightweight player in terms of welding processes. While it’s true that stud welding is highly effective in many small-scale applications, it’s equally effective in a wide spectrum of large-scale production.


Within each manufacturing industry, there are various applications of stud welding, big and small. When it comes to structure and building construction, stud welding has more uses than any other type of welding. With Northland Fastening Systems, you can find the services and tools you need for any construction stud welding project, no matter the scale.


Construction stud welding can be performed with capacitor discharge or drawn arc stud welding techniques, and it’s frequently used for a number of construction projects. Some common large-scale applications of stud welding in the construction industry include parking structures, high-rise buildings, stadiums, water towers, and bridges.


Bridges in particular require a specific approach to construction when it comes to the application of stud welding.


Stud Welds in a Bridge


Stud welding is used on many types of bridges. The primary functional role of stud weld points in the vast majority of bridges is to hold and and/or strengthen shear connectors to the concrete base:


  1. Connection Points: Stud welding is used to form powerful connections. This process permits contraction and expansion movement with temperature changes and wind affecting the bridge without compromising structural integrity.
  2. Plate Connection Points: Certain bridge components are made up of steel plating and other similar sections put together to form the full bridge structure. These sections are often connected using a stud welding process of tying them to concrete. Specifically, stud welding is often used to connect steel girders to concrete slabs combined with powerful meshes, forming a durable, flexible connection.
  3. Anti-Skid Studs. These studs create the rumbling effect that drivers hear entering and exiting a bridge.


Without the added strength and necessary allowance for motion in the face of weather and wind that stud welding provides, bridges would not be as safe and effective as they are today.

Threaded Stud Welding 101 – How to Use Our Threaded Stud Welds

Although we don’t provide threaded stud welding services, we want to help you use our products in the most efficient way possible.

We use our blog to educate people on the benefits of stud welding and its different applications because we understand how important it is to help you get the most out of our products.

Today, we’re going to discuss the basics of threaded stud welding.

After reading our tips, check out our inventory to find the perfect weld stud for your project.

Threaded Stud Welding 101

Stud welding is the process of joining metal parts together.

The difference between stud welding and traditional welding—stud welding happens instantly through a heated charge.

This process is faster, more efficient, and less costly over time.

There are different types of weld studs that are used for different purposes.

Some weld studs have threads —patterns in the metal—and some don’t. Different thread sizes are needed for different applications. If you have a question about which thread is right for your project, just ask us and we’ll find the perfect fit.

Let’s break down some of the differences between thread types and their use.

Full Thread Studs

Full thread studs have a thread running across the entirety of the stud from the top to the bottom.

Full thread studs can be used to weld on both flat surfaces and angled ones.

They have a wide variety of applications, including sheet metal fabrication and use in the automobile industry. If you need the full weld stud base for strength and the fillet weld will not get in the way of another part, a full threaded stud would be your best option.

Partial Thread Studs

Partial thread studs have a thread running along part of the stud instead of from top to bottom. They also have the ability to be used for welding on flat surface and angles, but they have slightly different applications.

If you’re concerned about the fillet weld getting in the way of a mating part or bushing, partial threads are the way to go. The weld end is smaller in diameter and the fillet weld generally stays within the thread diameter so it will not interfere with a mating part.  Their application is more versatile and can be better at holding certain types of objects in place. The non-threaded portion of the stud provides more shear strength, which means it’s better at holding the load of a resisting object.

Is Threaded Stud Welding Right for Your Job?

Again, we don’t provide threaded stud welding services, but we can help you find the right stud for your job.
