How New Technology and Better Stud Welding Products Make Industry More Sustainable

Since the beginning of the 20th century, stud welding began to be used more prevalently throughout industries beyond its original applications in shipbuilding. The several wars that the United States and much of the rest of the world faced also played a large role in the expanded use of strong, fast connecting systems like stud welding in manufacturing. Today, stud welding is used in most industries, from automotive to food grade equipment. However, many changes in the way people build are causing stud welding to develop once more to keep up with sustainability and energy-efficient designs. Over the last 10 years, engineers and fabricators have worked to improve the functioning lifespan, weight, and other properties of welded studs. If you are a manufacturer working with drawn arc, capacitor discharge (CD), or short cycle stud welding operations, you can find the high-quality supplies you need at Northland Fastening Systems (NFS). We provide a complete range of stud welding products, including tools for rent or purchase, studs, welding accessories, and our own welding technicians expert advice.

Stud Welding Products

Modern stud welding products already offer some of the most efficient systems for installing quick, powerful connection points and fastening technology. However, fabricators and manufacturing companies are still working to increase the range of those capabilities.

Setting Standards

Two major industries are setting sustainability and cost-saving guidelines for the rest of those who use stud welding on a large or heavy-duty scale. Power plants and shipbuilders have both researched and found ways to improve their use of studs with less waste and for longer use.

Power plants:

Most power plants use studs installed in operating furnaces to act as heat transfers into boiler tubes. These studs are typically made of 430 stainless steel with a refractory coating, and they have to be fully replaced about once a year. The replacement of these studs requires a large factory shutdown, which is both expensive and time-consuming. Some newer kinds of studs made from an iron and aluminum alloy have shown to last three to four times longer than 430 stainless steel studs. This new stud technology runs colder than older studs, transfers heat better, and forms anticorrosive aluminum oxide when exposed to furnace temperatures of 1,600-1,800ºF.

Shipbuilders:

Shipbuilders, especially those manufacturing naval vessels, have also found a way to eliminate cost and improve sustainable designs. A study released in 2012 showed that newer studs welding equipment with lower energy consumption during idle (between welds) could reduce shipbuilding costs on large vessels by $0.128 to $0.154 per stud. For shipyards that build destroyers and other navy warships, that could mean a reduction in cost of $589,000 to $708,000 in energy alone.

Newer technology across industries using stud welding products will only continue to prove how much more efficient and sustainable they can be. To learn more about the newest stud welding machines and the other products we offer, contact NFS at (651) 730-7770 or request a quote online.

International Standards for Stud Welding Supplies and Operations

Industrial standards for manufacturing operations, equipment, facilities, worker safety, materials used, and all other aspects of large-scale production work have developed over time since the turn of the 19th century. Today, industrial standards are highly regulated with hundreds of different certifications, licenses, and requirements that manufacturers and processors can meet to exhibit the quality of their products and the reliability of their practices. In the stud welding industry, many resources help companies receive certifications and follow the best standards available internationally. As a comprehensive supplier of stud welding supplies, Northland Fastening Systems (NFS) follows international standards, including the ISO 9001:2015 certification for quality management systems.

ISO 9001:2015

ISO 9001:2015 standards require an industrial facility to demonstrate its ability to consistently offer services and products that meet its customers’ needs and improve customer satisfaction while adhering to applicable regulations and requirements. This is a generic ISO standard, but there are thousands of other ISO certifications, including ones that apply to the welding industry and stud welding supplies.

For stud welding, including drawn arc, capacitor discharge (CD), and short cycle operations, one international standard that gets into specifics is ISO 13918:2017.

ISO 13918:2017

This ISO standard applies to the use of studs and ceramic ferrules in drawn arc welding. It can be used to cover standards for other metalworking industries, but it’s most useful for arc stud welding processes. ISO 13918 covers requirements for using stud types and ferrules, including dimensions, mechanical properties, and materials used.

Details apply to fully-threaded, partially-threaded, and virtually-threaded studs as well as threaded studs with flanges, studs with internal threads, and threaded studs with reduced shafts. Regulations also cover shear connectors and insulation pins.

Ceramic Ferrules

In addition, these standards cover the use of ceramic ferrules that contain molten metal at the connection point. Because ferrules need to be removed easily after the weld is performed, they need to follow strict rules for size, materials, and fabrication process.

ISO standards like 9001 and 13918 provide important guidelines for everyone in the stud welding industry. By following internationally accepted industry standards, companies are able to provide better services and products to their customers; operators can perform safer, long-lasting welds; and parts manufacturers can fabricate tools, studs, and welding accessories in universal formats.

Accessories for the Stud Welding Process

Stud welding is a complex process in many ways, but simple in others. The operation of a stud weld itself is a strong but straightforward connection point that fuses the metal of the stud into the metal of the base material. However, the actual process takes a deep understanding of arc generation, materials, dimensions, and the tools involved. In order to perform an accurate weld, you need the background knowledge and the right tools for the job. At Northland Fastening Systems, we provide the tools, studs, and accessories necessary for drawn arc, capacitor discharge (CD), and short cycle processes. When it comes to the accessories important to any stud welding process, our team of expert technicians can help you find exactly what you need.

Since 1987, we’ve supported and worked to continually improve the stud welding industry. One aspect of stud welding that is often overlooked is the use of accessories in the CD and drawn arc process. These accessories are completely necessary for an effective end result, but they can be taken for granted sometimes.

What to Consider before Buying Stud-Welding Equipment

With any kind of manufacturing tools, you need to do your research to determine what specifications, sizing, materials, and other details you’ll need depending on the job. Even with a simple tool type like a screwdriver, there is a large range of variations. When it comes to more complex manufacturing tools or whole systems like with stud-welding equipment, there are even more technical aspects to consider before purchasing even the studs you will use. Northland Fastening Systems (NFS) provides a complete range of stud-welding supplies from tools for rent or purchase to studs of any dimension, including customs options. In addition to a comprehensive supply of stud-welding equipment, our staff of knowledgeable technicians will guide you in selecting exactly the right tools, studs, and accessories you need.

While we at NFS make all our welding supplies as affordable as possible, we don’t want you to waste your time and/or money purchasing a tool or stud that won’t work for your job. To save yourself the headache of returns or wasted money, consider the following issues before buying stud-welding equipment:

Materials: Different stud-welding processes work best with different materials. If you’re working with thin stud-welding pins for stainless steel, food-grade welding, the best tools to choose will be for CD stud-welding operations. On the other hand, composite construction with bar anchors requires more heavy-duty tools for drawn arc welding. The surface material and the stud materials are both significant factors that will guide your stud-welding equipment choices.

Dimensions: Like the materials, the dimensions of the studs you’ll be working with will guide your selection of all stud-welding equipment.  CD stud-welding operations are suited to smaller studs like pins, insulator fasteners, and sheet metal connectors. Additionally, CD studs are best for thin surface materials because they don’t leave through-marking discoloration or warping. Drawn arc stud welding tools can handle larger stud dimensions and thicker base materials. Because they can handle much heavier duty dimensions, drawn arc welding studs are also used in building construction, structural steel applications, and composite construction for large-scale structures like bridges.

Automation: Another important aspect to consider before purchasing stud-welding equipment is whether you need options for automation or you’ll only be performing welds with hand tools. Automated tools can require different power calibrations, facility setups, and maintenance treatment. While handheld tools still perform rapid welds and are often useful as portable tools in the field, fully automated systems are key for many large-scale production operations. Determining whether you need automated tools for faster production will be a large factor in choosing the right stud-welding equipment.

Local Contaminants to be Aware of When Using Stud Welding Fastening Systems

Northland Fastening Systems provides supplies for operators using stud welding worldwide. From small shops to manufacturing plants and large construction sites, we supply tools for rent or purchase, studs in a complete range of dimensions, custom stud options, welding accessories, and the expertise of our welding technician staff. For drawn arc, capacitor discharge, and short cycle stud welding processes, NFS can provide everything you need to get the job done. If you’re working with stud welding fastening systems, it’s important to be aware of the potential problems that can be caused by a weld site’s exposure to local contaminants.

The most common issues welders face with local contaminants includes the following:

  • External gases: In many welding applications, shielding gas is a critical component of the process to protect the connection point from external gases that exist naturally around us. Exposure to prevalent gases like oxygen, nitrogen, and carbon dioxide around a welding site can cause porous, brittle connections. The use of shielding gases like argon or helium will create a protective bubble around the weld point, lending to stronger fastening systems.
  • Cold: While it’s not typically an issue, extreme temperatures can cause problems with stud welding fastening systems. Because welds will cool much quicker in cold weather than other more temperate conditions, cracking can occur with the shock of that temperature drop. Also, because the rest of a metal welding surface is typically much colder than the weld point, warping is also a potential issue. The easiest way to prevent these problems when welding in cold weather is to preheat a large area on your welding surface.
  • Particulates: Dust and other surface contaminants are one of the most significant concerns for welders using stud fastening systems. Particulates blown into a weld point can create a poor connection that is brittle or porous. Creating barriers outside and keeping your indoor welding spaces clean can solve many issues that dust causes.
  • Moisture: Humidity or other sources of moisture can cause issues for welders like corrosion on machines or damages to electrical systems. In severe cases, moisture can short circuit welding units and pose significant danger to operators and other workers. Keeping tools stored in dry, covered areas and maintaining a dry workspace solves many moisture issues.

There are other issues to be aware of such as tool maintenance, welding calibrations, material compatibility, and many additional aspects of the welding process, but these are the most common problems that operators face from contamination of a weld. NFS technicians can provide advice and guidance for working through any issues and equipment specifications you may need.

Testing Stud Welding Results

Like in any manufacturing industry, diagnostics are critical for production utilizing stud welding in any capacity. Since its first use in the shipbuilding industry during the early 1900s, stud welding has expanded into many types of fabrication, from composite construction with shear connectors to thin insulation fasteners built into many structures. No matter what type of capacitor discharge (CD), drawn arc, or short cycle stud welding applications you work with, Northland Fastening Systems (NFS) has the supplies you need. Our selection of stud welding supplies includes tools for rent and purchase, studs in a comprehensive range of dimensions, custom stud options, welding accessories, and the expertise of our own staff technicians.

 

Stud welding operations can be complex, depending on the weld, stud, and material types. Because of this, results diagnostics are key to determine whether a weld process needs any adjustments. Even simple welds with pre-calibrated tools require basic testing to see if a connection point is strong.

 

Basic Testing

There are standard mechanical and visual diagnostics that can be done to check the first few welds after calibrating a tool for the dimensions, weld type, and surface material, including:

 

  1. Form two test welds to an approved base plate material sample.
  2. Inspect the weld to see if there are visible flaws such as spattering, burring, slag, and so on.
  3. Bend each test weld to a 30-degree angle from its vertical point. This bend can be done with a hammer, pipe, wrench, or other tool depending on the stud diameter.
  4. Inspect the weld connection to see if cracks or other flaws have appeared after the stud was bent.
  5. If no flaws appear and the test weld passes initial visual inspections, you can continue with that calibration for the rest of your job using those stud and base plate specifications.

 

Threaded Stud Testing

When using threaded studs, similar basic mechanical and visual tests can be done. Like the preceding weld tests, inspect two welds to an approved base material sample to see if visual flaws are apparent.

 

To perform a mechanical test for a threaded stud, set it in a secured steel sleeve. Then apply a tensile load by tightening a nut and washer down to the sleeve with a torque wrench.

 

Other Tests

 When testing studs that must be attached to non-approved base plate materials, apply visual, tensile, and bend tests to at least 10 weld samples. These tests should be done until a stud failure. An accurate weld will see failure in the stud from metal fatigue, caused by repeat bend tests, rather than at the connection point.

 

Low-temperature welds can also be tested with a slow bend to 30ºF using a pipe. Impact tests are not useful when welding in low temperatures (50ºF or below).

 

Accurate testing can protect your final results from potential failure in any stud when applied in an assembly. To learn more about stud welding and the supplies and expertise we provide, contact NFS by calling (651) 730-7770 or requesting a quote online.

Part One: Shielding Gas and Its Role in the Stud Welding Process

In many manufacturing industries, stud welding is often relied upon for its ability to create powerful fastening systems quickly and cleanly. The industries that the stud welding process is utilized in range from food grade manufacturing to composite large-scale construction.

 

As a type of arc welding, the stud welding process is capable of forming connection points that are stronger than the stud or base material. There are several types of stud welding processes, including drawn arc, capacitor discharge (CD), and short cycle welding.

 

At Northland Fastening Systems, we provide a comprehensive supply of tools, studs, and accessories for each stud welding process as well as the expert advice of our own technicians.

 

Compared to other types of arc welding, stud welding is a relatively straightforward process with few bells and whistles required to perform a strong weld. For example, technicians performing other welding processes require significant personal protective equipment and often shielding gas, slag, vapor, or other weld protective measures must be taken. The stud welding process is designed to be performed rapidly, easily portable in the field, and require only basic training for the welding technician.

 

CD and short cycle welding in particular are streamlined, fast operations compared to many other welding techniques. However, they are only suitable for a “lightweight” range of duties and are limited to smaller studs and overall moderate applications. Drawn arc welding, on the other hand, can be used in large-scale applications like composite construction for bridges and buildings. Because drawn arc welding utilizes additives like shielding gas and ceramic ferrules that other arc welding processes use for various operations, it’s capable of installing larger studs and heavy-duty manufacturing.

 

Typically, drawn arc welding uses a ceramic ferrule ring to contain the heat generated at the weld point and a flux tip to control the melt temperature. Using these additives in the stud welding process helps control the fusion and create a clean weld result. Welders can also use shielding gas in the place of a ferrule ring.

 

Shielding gases like argon, carbon dioxide, and helium are inert, and when applied during the welding process will protect the weld from air contaminants like water vapor and oxygen that would otherwise create a porous weld prone to cracking and corroding. When applied in a drawn arc stud welding process, shielding gas also helps control the arc, prevent splatter, vary penetration depth, and more.
