Part 2: Attaching Welding Studs to Advanced High-Strength Steel Automotive Surfaces

Posted on by norfas by norfas

Part 1 of this two-part blog series covers the development of advanced high-strength steel (AHSS), also known as automotive steel, and the first-generation AHSS categories, which includes a brief description of first-generation ferrite and martensite-based steels such as DP, MS, CP, and TRIP steels. In Part 2, we  cover second-generation steels and the use of AHSS in the automotive industry. Since the beginning of AHSS development in the 1990s, these materials have slowly begun to replace various steel and aluminum components in multiple vehicles. In many instances, AHSS offers a higher crash resistance than aluminum and is lighter than other steels, making vehicles both safer and more efficient. As with aluminum and any other steel parts, many AHSS components of modern vehicles are constructed with stud weld fastening systems. Stud welding is a mainstay in automotive manufacturing. Not only does it provide a powerful, clean connection point that can be quickly installed, it’s also cost-effective, leak-proof, and only requires access to one side of a work surface. At Northland Fastening Systems (NFS), we work with multiple customers in the automotive industry to supply welding studs, accessories, and other equipment.

Welding Studs

Fastening welding studs to AHSS surfaces requires an understanding of the correct stud materials and dimensions, as well as tool and power calibration, but it can easily be done. Many manufacturers working with AHSS have quickly transitioned their stud welding technicians to these newer materials.

AHSS Material

The second generation of AHSS materials are based on austenitic microstructures. Current second-generation high-strength steels include:

  • TWIP steel: Twinning-induced plasticity (TWIP) steel has excellent mechanical properties at room temperatures. It is highly resistant to corrosion with outstanding strength and energy absorption greater than twice the ability of previously used steels.
  • L-IP steel: Lightweight with induced plasticity (L-IP) steel is a lighter version of other TWIP steels. They are high-manganese alloys that have high-impact resistance and stretch, forming properties ideal for automotive parts.
  • SIP steel: Shear band formation-induced plasticity (SIP) steel is another material based on TWIP alloys. When shear band force is applied to SIP steel, structures are actually strengthened in the austenitic matrix.

AHSS in Welding Studs

Both first- and second- generation AHSS types are utilized in the manufacturing of vehicles ranging from daily drivers to public transportation. Not only are these steels stronger than conventional steels and aluminum, they are also lighter, more sustainable, and even more affordable than previously used materials. These steels are utilized in modern vehicle parts that will absorb shear force, high-energy resonance, shock, load bearing, and many other critical components.

If you’re working with AHSS in the automotive industry, or any other application such as aircraft, shipbuilding, or general manufacturing, stud welding is likely one of your primary fastening systems.

Part 1: Attaching Welding Studs to Advanced High-Strength Steel Automotive Surfaces

Posted on by norfas by norfas

The earliest forms of welding, dating as far back as 1,800 BCE, forged basic bronze and irons into various weapons and tools. Over the centuries, more sophisticated uses of metal developed, such as the pattern welding used to make Damascus steel and Japanese swords. When electricity was harnessed in the 1800s, resistance-welding technology was quick to advance. Today, we have many resistance-welding techniques and other arc-welding operations that utilize electricity to heat metals. Stud welding is one of many modern operations that use specifically calibrated electrical currents to fuse metals. While it’s implemented extensively throughout multiple industries, stud welding is also a frequently used fastening technique in the automotive industry. In the past 10 years, car companies have replaced a large number of other steel and aluminum stud welded parts with advanced high-strength steel (AHSS) due to its weight and crash resistance. If you’re working with AHSS and welding studs, you can find all the supplies and technical support you need with Northland Fastening Systems (NFS).

Welding Studs

NFS offers a complete supply of drawn arc and CD studs, welding tools for rent and purchase, accessories, and the advice of our own welding technicians. We also provide repair services for the majority of stud welding models.

Because one of the most prevalent uses of AHSS is for automotive parts, the different types of those materials are often discussed and classified as automotive steels with a minimum tensile strength of 440 MPa.

Welding Studs with AHSS Materials

There are two generations of AHSS materials. The first generation of AHSS includes ferrite and martensite-based steels, while the second-generation group are steels based on austenitic microstructures. Attaching welding studs of any dimensions to an AHSS work surface requires an understanding of the steel itself.

  • DP Steel: Dual-phase (DP) steel is a first-generation ferrite-based steel category. DP’s high-strength steel grades have low-yield strength to tensile strength ratios, high-fatigue resistance, and uniform elongation properties.
  • MS Steel: Martensitic (MS) steel is a first-generation stainless steel alloy. It can be tempered and hardened with heat treatments to become highly durable, wear-resistant, and strong in mechanical applications.
  • CP Steel: Complex-phase (CP) steels are extremely fine-grained with micro ferrite structures. They have high work-hardening properties, high-fatigue strengths, wear-resistance, and can absorb high energy resonance.
  • TRIP steel: Similar to CP steel, transformation-induced plasticity (TRIP) steel has a high-yield strength for first-generation steels. Their microstructures of austenite can be transformed to martensite structures when bearing load or being deformed.

Summary

In the second part of this two-part blog, we discuss second-generation AHSS steels and all AHSS applications in the automotive industry. If you’re working with welding studs on an AHSS work surface or any other materials, you can find the supplies you need with NFS.

Advantages of Stud Welding over Other Fastening Systems

Posted on by norfas by norfas

Throughout manufacturing history, many methods of fastening one component to another have been implemented, ranging from the most rudimentary nails to the most advanced industrial adhesives. The best fastening systems in any given situation depend on several factors, such as materials, dimensions, function, and finish. When it comes to fastening steel, aluminum, copper, bronze, and many other metal components, stud welding is often the superior choice. When properly applied, welded studs have a connection point that is quickly applied, mark-free, and powerful. In addition to stud welding’s use for metal fasteners, it’s also a key part of composite construction for steel and concrete builds. Northland Fastening Systems (NFS) is a supplier of all the necessary tools, studs, and accessories for drawn arc, CD, and short cycle stud welding operations. We offer customers a complete selection of welding materials and equipment, including our own technicians’ expert advice and guidance.

Fastening Systems

While stud welding is just one of many fastening systems for multiple applications, there are several ways it outperforms other techniques and provides greater advantages in comparison. Some of the most common fastening techniques that stud welding outperforms include:

  • Bolting: Conventional bolting is a frequently used fastener because it’s highly accessible and generally cost effective. In comparison, stud welding installation costs are actually lower and faster. Two-sided access is not required to install studs, and they can be installed without a visible head. Stud welding is also resistant to leaks and vibration, and does not require through-hole preparations.
  • Boring, drilling, and tapping: Stud welding is a faster process than any boring, drilling, and tapping operations. It has a lower install cost, does not require through-hole preparation, and has better resistance to resonance and leakage. Most important, stud welding doesn’t leave marks on the reverse side of the installation surface.

More Uses

  • Soldering: Unlike soldering, stud welding can be applied to painted surfaces and it generally calls for less training time. Stud welding is faster than soldering and has lower installation expenses.
  • Clinch fastening: Clinch fastening requires high-pressure application and two-sided access to the connection surface. Stud welding needs neither of these for a successful connection, and it doesn’t leave marks or a visible head. Stud welding requires no preparation for a through-hole, and it resists leaks and vibration. Also, clinch fastening equipment is not portable, whereas many stud welding units can be easily moved throughout a job site.

In almost every instance in which one of these common fasteners can be used, stud welding can replace it for faster, stronger, cheaper, and better-looking results. If you’re working with any of these fastening systems, consider replacing those operations with stud welding. For more information, contact NFS at (651) 730-7770.

Specialized Groups of Construction Equipment Built with Steel Weld Studs

Posted on by norfas by norfas

There are many tools and types of equipment we use daily that are built with stud welding processes. From the cars we drive to the appliances we use in our kitchens, stud welding operations are frequently called on for efficient, strong fasteners throughout various industries. The prevalence of stud welding being used for various fastening systems is due to its many benefits. Stud welding creates a powerful connection point with clean results. It can also be used in fastening multiple materials, including steel, aluminum, copper, and brass, and it’s reliable for composite construction to combine materials like concrete and wood to steel beams. If you’re working with steel weld studs on your production floor or job site, you can find everything you need to get your project completed at Northland Fastening Systems (NFS).

Steel Weld Studs

One major use of steel weld studs is in the manufacturing of construction equipment. Common construction equipment, such as excavators, cranes, dump trucks, and backhoes, are all built with steel studs, but many specialized types of equipment also rely on the use of stud welding in their fabrication.

  1. Dragline excavator: Used typically for excavation at greater depths, a dragline excavator has a long boom with digging buckets suspended from cables. These excavators are critical for the removal of sediment underwater. They are used in the construction of ports, marinas, canals, and for clearing pathways for water traffic.
  2. Trenchers: For pipe laying, cables, irrigation, drainage, and other systems, trenchers are used to dig long, deep ditches in the earth. They have a fixed arm with a digging chain or tooth-bladed digging wheels. Wheeled trenchers are best suited to cut through hard-packed earth and gravel.
  3. Pavers: In road construction, pavers are essential when applying asphalt. Pavers have feeding buckets that are loaded continuously with a dump truck as the paver evenly distributes asphalt on the roadway. They provide partial compression to the asphalt, but a roller must go over the surface as well for full compaction.

 More Uses

  1. Telehandlers: Telescoping handlers are hoisting machines that can lift heavy-duty materials or equipment up to construction scaffolding and platforms. They can also raise and lower workers to different job-site levels with buckets or cabins.
  2. Feller bunchers: In logging and site clearing, feller bunchers are large-scale grips that can hold trees, make a cut, and move large branches without the trees felling. Felling trees makes for a dangerous worksite, but a feller buncher helps quickly and efficiently remove trees and free up a site for dump trucks and excavators to enter.
  3. Piling equipment: Foundation construction requires the boring or driving of piles into the earth. Pile borers can drill holes into the ground, and hydraulic drivers ram the pile into the ground to the required depth.

For any of the preceding construction equipment, you can count on us to supply you with the correct steel weld studs and other materials. Contact NFS at (651) 730-7770 or you can request a quote online for more information.

 

 

Full Scope of Applications for the Stud Welding Process

Posted on by norfas by norfas

Compared to many other manufacturing operations, stud welding is a relatively young technology. The first uses of stud welding didn’t occur until after World War I in the early 1900s. Early stud welding was used in composite construction to fasten wood to steel beams in the shipbuilding industry. Today, stud welding is still used in shipbuilding, but it’s also heavily utilized across multiple industries for a vast range of applications. As a fastening system, stud welding creates powerful connections quickly without needing access to two sides of a work surface and without leaving marks on the reverse side of the weld. If you’re working with any kind of stud welding process you can find all the supplies you need with Northland Fastening Systems (NFS).

Tagging, Name Plating, Insulating, and Other Small Diameter CD Stud Welding

Posted on by norfas by norfas

Different types of stud welding operations each have its own range of applications in a broad scope of industries. Not only has drawn arc stud welding been used for shipbuilding since the early 1900s, it’s also used today for automotive production, bridge and other infrastructure construction, multi-story buildings, construction equipment, and many other manufacturing industries. CD stud welding has its own wealth of uses, from food grade equipment fabrication to the installation of insulation materials. No matter what type of stud welding you’re working with, you can find the supplies and support you need with Northland Fastening Systems (NFS).  NFS provides a comprehensive selection of studs, welding tools for rent or purchase, welding accessories, and even repair services for most welding models. Our team of expert technicians also offers guidance and support for any of your welding questions.

CD Stud Welding Operations

While many drawn arc and CD stud welding operations are used in heavy-duty to mid-size construction, there are also valuable small-scale applications that use studs and pins with diameters under ¼” wide.

Uses of CD Stud Welding

Some of the most prevalently used small-scale CD welding solutions include insulation, name plates, and other labeling systems.

  • Insulation pins: NFS offers 1″-long, 10-gauge diameter standard CD insulation weld pins made from mild steel. These pins are highly useful in quickly and effectively attaching insulation in a broad range of construction scenarios. Insulation for pipes, building interiors, HVAC ducts, industrial equipment, incinerators, and many other locations can be installed using CD welded insulation pins.
  • Name plate studs: Another CD welding application is the installation of name plates with breakaway studs. These studs are tipped with small domed pins that break away from the part inserted into the weld gun. Name plates on equipment that show models, serial numbers, and many other specifications are almost exclusively installed with these welding studs. They are also used in installing small signs and even for decorative purposes.
  • Tag welding: Not to be confused with TAG (Tungsten Active Gas) welding, tag welding is an effective labeling system for steel part inventories. Tags can be quickly installed on a bare steel part, such as beams, rebar, and billets, with a connecting CD stud. Tagging materials with CD studs can easily provide clear labels that won’t get lost or break off. The installation process takes seconds and is a cost-effective organization solution.

Summary

These three types of small-diameter CD stud welding are key to many production and construction operations. They offer a strong fastening system with quick, reliable operations.

History of Sheet Metal and Arc Stud Welding

Posted on by norfas by norfas

While general welding dates back to the Bronze Age, the history of stud welding is much more recent. The first stud welding operations were developed in the early 1900s in the shipbuilding industry. Those early operations were rudimentary compared to the capabilities of stud welding today. Modern stud welding can be done manually on a jobsite or in an automated capacity in the manufacturing facility. Either way a weld is performed, when done correctly, it will generate a connection point that is clean and stronger than both the stud and surface material. Stud welding is used across industries from the automotive sector to food service supplies. Whatever kind of project you’re working on, you can find all the stud welding supplies you need with Northland Fastening Systems (NFS). NFS has a complete supply of materials for capacitor discharge (CD), short cycle, and drawn arc stud welding, including studs, tools, accessories, and even repairs.

ARC Stud Welding

One of the main reasons why arc stud welding and other stud welding operations are used so prevalently across industries is because of their compatibility with sheet metal and the fasteners used to build with those materials.

Arc Stud Welding Uses

Sheet metal has its own large range of specifications, such as thickness, material type, manufacturing technique, and surface treatments. Even with this range, however, stud welding is often a useful operation for attaching sheeting to other structures, fixing studs and other fasteners to sheeting surfaces, and thru-deck welding to connect sheeting to steel beams.

Uses for Sheet Metal

Humans have used sheets of metal for centuries. The oldest metal sheets were hand-hammered and used for both decorative and functional purposes. The first idea for a rolling mill is credited to Leonardo da Vinci from a sketch drawn c. 1485, but the first recorded accounts of water-powered sheet-rolling mills didn’t occur until the early 1500s. Check out the following timeline:

  1. 1485: Leonardo da Vinci makes several sketches detailing his idea for a rolling mill.
  2. Early 1500s: Some records show two rolling mill designs that were used to make gold sheeting for coins.
  3. 1600s: The use of a puddling technique for sheet metal was used. This method is somewhat effective, but often loses over half of the iron content into the sand bed while the metal is molten. The puddling method was used to make metal sheets that are part of the Eiffel Tower and the Statue of Liberty.
  4. Late 1600s: The first tests of rolling iron to make tinplate occurred around 1670. Ironmaster Major John Hanbury built rolling mills for tinplate and black plate.
  5. Late 1700s and the Industrial Revolution: The beginning of modern sheet metal manufacturing began during the industrial revolution. The first iron casting techniques were developed in the early 1700s. By the time of the industrial revolution at the end of the 18th century, rolling and casting sheet metal processes began to be perfected.

Summary

Today, many applications of arc stud welding and sheet metal are used across the manufacturing world. To learn more about the stud welding supplies we provide, contact NFS at (651) 730-7770 or request a quote online.

Strength of Complete Fusion in the Stud Welding Process

Posted on by norfas by norfas

Since its invention in the early 1900s, stud welding has proven to be an exceptionally useful tool for a wide range of industries. From construction to electronics, stud welding offers a fastening system that connects metals with strong, rapid, and clean operations. When applied correctly, stud welded connections are stronger than the stud and base material put together. In fact, one of the quickest ways to test the accuracy of a weld is by seeing if the stud will fail in a bend test before the connection point fails. If you are working with stud welding, you know the benefits it provides to many manufacturing processes. Stud welding is quick, cost-effective, and powerful. At Northland Fastening Systems (NFS), we provide a complete range of supplies for the drawn arc, capacitor discharge (CD), and short cycle stud welding process. This includes studs for each type of welding, tools for rent and purchase, welding accessories, and even repairs for most welding equipment.

Stud Welding Process

One of the reasons why the stud welding process is advantageous for so many industries is because of the strength a full fusion weld point provides. Stud welding operations completely fuse stud materials to surface materials. This fusion can be done with a variety of metals, including steel, aluminum, and even copper.

What Is Complete Fusion?

Complete fusion requires both metals to reach melting temperatures. Molten metals will fuse together at the weld point and create a complete connection between parts. All layers of stud and surface material should be molten in order to create complete fusion. Because of this requirement for deep penetration, stud lengths will shorten a specified amount when installed, depending on material and weld types.

A homogenous weld point that is completely fused will be clean with no spatter or puddles. Complete fusion eliminates the risk of a cold or porous weld that will likely fail. Any incorrect applications that have incomplete fusion can be revealed with testing. Incomplete fusion issues can be prevented by accurately calibrating welding equipment, using the right power, and performing a weld in the correct duration and positioning. With drawn arc welding, ceramic ferrules and shielding gas also help technicians achieve complete fusion in the welds.

Summary

For complete fusion through paint, annealing, and other surface treatments, technicians should adjust accordingly and use grounding clamps on the job site. In facilities where automated stud welding systems are integrated into a production line, complete fusion results are often built into the equipment. Automation parameters for complete fusion can be adjusted when stud dimensions, materials, and other specifications are changed.
