Drawn Arc Stud Welding Highlights from Start to Finish

Drawn arc welding is a complex process made simple with today’s technology. Though welding has been around for centuries, beginning with the oldest forge welding to today’s capacitor discharge welding, it hadn’t begun development into the highly advanced process contemporary welders use until the late 1970s. Thanks to the advancement of welding techniques since then, we are able to utilize both drawn arc and capacitor discharge processes to perform stud welding operations. If you are working on a CD or drawn arc stud welding project, Northland Fastening Systems has everything you need from tools for rent and sale, studs of all shapes and sizes, stud welding accessories, and our own welding services.

 

When it comes to the traditional format of drawn arc stud welding, there are several stages of the procedure to take into consideration. First, the welding operation itself, which follows a simple step-by-step process:

 

  1. The welding gun is set onto the base material at the desired weld point and the operator compresses the main spring partially.
  2. The trigger is then compressed, and the stud is lifted magnetically from the base material to create an arc.
  3. The arc melts the stud tip and the base material while a ceramic ferrule shield concentrates the heat, containing it to one weld point.
  4. The stud is then compressed into the base material, melding the two molten metal components.
  5. The welding gun releases the stud, the ferrule is broken, and the welding process is complete.

 

A drawn arc stud welding process creates a bond that is stronger than the stud itself. As welding processes go, drawn arc welding is one of the most effective, fastest, and strongest operations for stud welding manufacturing. For even more effective, accurate drawn arc stud welding, templating is a highly useful procedure.

 

Templates improve the accuracy of a welding operation that uses a ceramic ferrule to contain the heat during the arc. Steel plates hold the ferrule in place, while spacers allow the gasses from the weld to escape through gaps underneath the template plates. Additional template options may allow tube templates with ventilation holes to hold the ferrule, or brushing templating can be applied.

 

Brushing templates allow for angled alignment of the stud in addition to an exact location. These templates use a tube adapter to sheath the stud and tilt it to the desired angle. The tube adapter is connected on one end to a foot component that can be attached to the welding gun and on the other to the ferrule. Template brushing components made from masonite or ebonite are stationed between the template and the tube adaptor. These components protect your template’s longevity and improve the accuracy of the weld. Virtually all drawn arc welding operations benefit from the use of a template.

Technical Specifications and the Engineering of Stud Welding

As one of the most versatile and widely used fastening systems, stud welding is an invaluable operation for a broad range of manufacturing industries. Because of its wide range of uses, stud welding has to meet a large number of engineering specifications, such as sizing, strength, materials, format, and process specifications. For any stud-welding project specifications, Northland Fastening Systems provides services and offers equipment, studs, accessories, and everything you need to get the job done.

 

Stud welding can be performed with drawn arc welding or CD welding units that vary in sizes, portability, and capability. Though both drawn arc and CD welding are rapid operations that provide a weld connection stronger than the stud and surface material combined, they differ in several ways when it comes to the engineering specifications.

 

Drawn Arc Stud Welding

  1. Materials used:
    1. Low-carbon steel with tensile strength of 60,000 psi minimum, a yield strength of 50,000 psi minimum, and a 20% minimum elongation in 2 inches. When annealed, the tensile strength becomes 50,000 psi, yield becomes 35,000 psi, and elongation becomes 25%.
    2. Stainless steel with tensile strength of 85,000 psi minimum, a yield strength of 40,000 psi minimum, and a 45% minimum elongation in 2 inches.
  2. Stud fastening torques:
    1. For low-carbon steel with studs ranging from 8-32 to 1”-8: between 17.8 and 2831 lbs per inch.
    2. For stainless steel with studs ranging from 8-32 to 1”-8: between 19.8 and 3440 lbs per inch.

 

CD Stud Welding

CD welding studs use a variety of materials from steel to brass. Each stud material provides a successful weld that is dependent on the base material. Some are more suited to a base material than others. For example:

  1. Mild steel:
    1. Excellent when welded to other mild steels, galvanized sheet materials, structural steel, stainless steel, and lead-free brass, rolled copper, and electrolytic copper
    2. Good when welded to medium-carbon steels and die-cast zinc alloys
    3. Cannot be welded to common aluminum alloys
  2. Stainless steel:
    1. Excellent when welded to mild steels, galvanized sheet materials, structural steel, stainless steel, and lead-free brass, rolled copper, and electrolytic copper

Building Water Towers

 

Because water towers have to withstand the weight of thousands of gallons of water and the pressure that weight imposes without contaminating the water with rust and other corrosion, building water tower structures is highly specialized work. Stud welding is a key manufacturing technique for the building of several water tower components including:

 

  • Structural legs that support the tank
  • Interior tubing running from the tank to the ground
  • Structural supports placed strategically on the legs and tank
  • Access ladders, stands, railing, and panels for maintenance workers
  • Any additional sheet metal components unique to each tower ranging from cosmetic to structurally integral

 

Water towers have to be safe, sealed, and weather resistant. They are a vital part of many city plans and communities, providing clean, healthy water to the residents and businesses. The production of tight, durable, long-lasting components of water towers is something our stud welders take very seriously. With our stud welding capabilities, the production of sheet metal parts for many structures, including water towers, is a streamlined operation.

 

Not only does NFS offer sheet metal stud welding services for large structures, we also provide sheet metal stud welding for smaller components that don’t have to hold up to extreme conditions but require the clean look of stud welding.

Arc Welding – What is Arc Welding and How Does it Benefit Your Metal Working Needs

Arc welding is a type of stud welding technique with specific applications we’ll cover in this article.

In today’s post, we’ll show you why arc welding is so effective, which materials it works best for, and provide recommendations for using arc welding based on the job, industry, and more.

Before we dive into the topic of arc welding itself, let’s talk about the benefits of stud welding for metal workers.

The Stud Welding Difference

You’ve heard the concept of welding before.

It’s simple – welding is the process of connecting one metal to another. You can use a variety of techniques like x, y, and z.

Stud welding saves time, money, and materials by creating a more efficient way to connect these metals. With arc welding, the stud joins the piece of metal instantly because it heats the stud and metal at the same time.

You may be wondering why this is important.

Joining the stud and the metal at once creates a tightly knit and more durable bond. This means the structure you build with arc welding will maintain its strength longer.

There’s also less room for error and the need for rework. When you don’t use stud welding, you need more effort and put yourself at risk of having to reweld that part if the bolts don’t connect properly. Also, the “clinching process” of welding isn’t as strong or long-lasting as stud welding because the bond isn’t as strong as heating multiple parts at once.

You can see how this would lead to cost savings, too. It’s a simple equation — less labor time, less need for re-work, and fewer materials needed equals lower cost.

At Northland Fastening systems, we promote stud welding not only because we sell stud welding products, but because the process is simply better and easier. 

Let’s dive into the need to know details of arc welding and how it can apply to your needs.

Arc Welding Explained

In the arc welding process, the electric arc fuses metal together with heat generated by the electricity. This method differs from using gas, which is less efficient.

Arc welding can use both DC and AC electrical currents. This is important because not all welding units accept both currents. Arc welding fuses the stud using an electrode. This electrode conducts the electricity needed to generate the heat.

When arc welding, you can feed the electrode automatically over and over again. Why is this important?

There are certain processes that benefit from this automated technique:

  • Flux Cored Arc Welding (FCAW)
  • Gas Metal Arc Welding (GMAW)
  • Submerged Arc Welding (SAW)

If your machine shop or manufacturer uses these processes, arc welding helps complete them in the most efficient way.

The process also saves time in the following ways:

  • No need to switch parts like filler rods
  • Less chance for heat distortion – in other welding processes, spreading out the heat too much can distort the parts being fused together.
  • Decreases deposition rate – meaning you won’t use as much metal
  • Switching from manual to automatic processes (when this applies)

If you’re a machine shop owner or operator, the technical benefits are clear.

For purchasers working for companies with manufacturing needs, you can talk to your company about switching to this often easier and more efficient process. In many cases arc welding can be a more affordable solution because the process requires less equipment.

Applications

It’s important to know how this process works for different needs and industries.

It’s a process that works well for many applications, but here are some core industries where it works best.

Sheet Metal Fabrication

Sheet metal fabrication is often used for these industries:

  • construction – commercial, residential, and industrial
  • manufacturing equipment
  • kitchen equipment
  • elevators
  • shipbuilding – specifically hydraulic presses

Here’s the main benefit of stud welding for sheet metal fabrication — appearance.

Stud welding fuses metals together without leaving many marks. Think about the benefits of this seamless process. Your equipment, parts, and structures will have the look and feel of a precision part formed from scratch, even though the parts are fused together. This gives an added professional look. Details matter in all structures and having that clean look and feel can make a better impression on people who see them.

Again, the process is also more efficient because of the speed and it creates more durability.

Agriculture Equipment

To explain the process simply, different types of agricultural equipment have many large pieces of metal that are fused together like the chassis, cab frame, fenders, and brackets

The farm industry requires durable and strong parts for its equipment. The stud welding process is used in some of the most important machinery in the world.

It’s best to use the stud welding process in an industry we all rely on so much.

Lawn and Garden Equipment

Similar to agriculture equipment, although not as large in scale, you want your lawn and garden equipment like lawn mowers to have tightly fused and strong frames.

Other outdoor equipment like barbecues benefit from the seamless look of having arc welded parts

Hospitals, Schools, and Other Facilities with Industrial Needs

We won’t dive into the details of the large number of different pieces of equipment needed to run these facilities.

The point here is to focus on the importance of having a quick and reliable solution in industries where efficiency has a big impact.

Anytime you are working on a large project, time and money are of the utmost importance. Loss of materials, time spent on rework, the need for more labor, and less efficient processes can have a huge impact on your bottom line.

If you are building a new facility or revamping your current one, consider a stud welding solution to meet your needs quickly and in a cost-effective way.

A Step by Step Understanding of Drawn Arc Stud Welding and Its Benefits

When it comes to manufacturing products that demand high-quality fast welding operations, stud welding is the best option for a wide range of sizes and materials. While CD stud welding is great  for connecting thin components quickly and with little marking on the weld-opposite part side, drawn arc stud welding is a key process for many different types of weld-based manufacturing. Northland Fastening Systems specializes in providing stud welding services for a variety of industries and stud welding supplies and tools for CD stud welding and drawn arc stud welding alike.

 

From construction equipment manufacturing to structural steel fabrication and more, Northland Fastening Systems provides the comprehensive stud welding services and supplies our customers need to build high-quality, long-lasting products using both CD and drawn arc operations.

 

At Northland Fastening Systems, we use drawn arc stud welding to perform rapid, precise welds for durable connections on studs ranging from .125” in diameter to 1.25” diameter. While thickness, length, and thread variants may be different from project to project, the drawn arc stud welding process remains consistent between jobs.

 

Drawn arc stud welding involves a number of steps and apparatus, structured as the following:

drawn-arc-stud-welding

While drawn arc stud welding is a relatively simple process on paper, it would not be possible to perform this operation without advanced welding equipment and studs made from high-quality materials. Not only does Northland Fastening Systems provide specialty stud welding services using state-of-the-art welders, control units, and studs, we also provide rental and sale of the very same HBS, Tru-Weld, and Midwest Fasteners quality equipment we use ourselves.

Today, even within the welding field, capabilities and equipment have expanded in leaps and bounds with advanced services in automated welding, capacitor discharge (CD) welding, and much more. At Northland Fastening Systems, we specialize in stud welding operations including providing state-of-the-art equipment and high-quality steel weld studs for drawn arc stud welding and CD stud welding.

 

When it comes to stud welding of any kind, it’s impossible to form a strong connection without the best quality steel weld studs. Northland Fastening Systems supplies the best quality steel weld studs made from only the highest quality materials for all your stud welding needs. Our products range from flanged and non-flanged CD studs to virtually all specifications of drawn arc studs.

 

We’re committed to providing as wide a variety as possible for studs and offer special sizing on request because of the highly exacting sizing specifications and performance demands all of our customers’ projects require.

 

Each project may demand very precise applications and types of welding studs – making it a complicated and nuanced process to apply stud welding to any product – but this demand is for good reason. Each welding procedure itself is different, but all are effective and innovative in their own way. For example, there are many differences between CD stud welding and drawn arc stud welding, but both are effective and beneficial when applied to the right project.

 

Drawn Arc Stud Welding

 

The stud is welded onto a work plate using an arcing current and a ceramic ferrule flux, forcing the stud to join with the plate.

 

Drawn arc stud welding is utilized to weld studs with larger diameters than CD stud welding. For studs up to 1¼” in diameter, drawn arc stud welding is an efficient way to fasten studs to heavier bases resulting in a stronger, more durable connection than CD stud welding. Drawn arc welding also benefits from its use of ceramic arc shields that maintain the weld and a direct current allowing for the use of 220 to 440 volt power sources during the welding process.

 

CD Stud Welding

 

The stud is welded onto the work plate with downforce and a capacitor discharge heating the plate to molten metal. The weld bond is formed after the metal cools.

 

CD stud welding is a highly efficient way to perform rapid welding operations for thin studs and sheet metal materials. It can be used for studs up to ⅜ diameter for up to 20 welds per minute, making it the fastest stud welding procedure. Additionally, CD stud welding leaves a cleaner weld with no marking on the opposite side of the work plate and it can be used to weld different metals. CD stud welding only requires 110 volt power sources.

See the Difference Steel Weld Studs Make for Yourself
