Category: CD Stud Welding

From residential buildings to skyscrapers, there are varying methods used to construct the skeleton and other foundational components of different building types. Homes and other residential buildings are typically built with lumber skeletons, while skyscrapers and other multi-level commercial buildings require steel beam structures. One common fabrication operation used in virtually almost any building type is stud welding. Stud welding is a versatile construction tool that plays a role in a broad range of building processes. For example, stud welding with shear connectors can allow workers to build composite constructions with concrete and steel. Stud welding can also connect steel beams, create foundations, and much more. If you’re using stud welding in building construction, Northland Fastening Systems has the tools, studs, and accessories you need for drawn arc, short cycle, or CD stud welding.

CD Stud Welding

In any type of building construction, CD stud welding is commonly used to install different types of insulation. Insulation helps conserve energy when heating or cooling indoor spaces, protects areas where fire is a potential issue, lowers interior noise pollution, and more. The following are just a few of the many different types of insulation used today in building construction.

Thermal:

Thermal insulation or weatherizing insulation is the most prevalent type of insulation material used in all types of buildings. These types of insulation are almost always required in residential and commercial buildings in order for them to meet municipal and state construction standards. Industrial buildings may not require thermal insulation, but it’s often in the best interest of a company to include insulation for energy costs, climate-control, and equipment protection. Thermal insulation such as batting and blanket fiber sheets, foam, fiberglass, and more are installed with CD weld pins and other stud insulation fasteners.

Acoustic:

For many indoor spaces, acoustic insulation reduces background noise, exterior noise pollution, and prevents sound travel between rooms. Acoustic insulation is used between apartments, offices, condominiums, and other spaces that are in multi-tenant buildings. Noise insulation is also a key component in buildings used in the entertainment industry, manufacturing industries when sonic diagnostics are necessary, and even in hospital buildings and treatment centers to protect patients. Acoustic insulation sheeting and other formats are installed with CD welding tools and studs.

Fire:

Heat-resistant panels, flame retardant sheeting, and many other types of fire insulation are a necessary installment in most buildings for safety purposes. Fire insulation is used in boiler rooms, electrical hubs, roofing, and many industrial applications. Mineral wool, radiant barriers, ceramic fiber, duct wrap, thermal batting, and other kinds of soft fire insulation are installed with CD pins. Electrical enclosures and other metal sheet flame barriers and fire-resistant panels are built with stud welding as well.

One of the main reasons why composite construction holds the strength it does for applications like road, bridge, and building fabrication is because of stud welding. Stud welding with shear connectors and bar anchors allows workers to connect concrete to steel beams and other girders. For most large-scale construction projects, composite construction is a key component of building with accurate, durable, and long-lasting designs. For any stud construction welding needs, Northland Fastening Systems (NFS) has the supplies to get the job done. From studs in a complete range of dimensions and custom options available to welding tools for rent or purchase, NFS is a comprehensive resource for stud-welding supplies. In addition to a full range of tools, studs, and accessories, our welding technicians can provide tool repairs and give guidance for best practices in whatever you’re working on.

Stud Welding in Construction

Stud welding in composite construction is performed with drawn arc operations to install fasteners that form structural connections between steel beams and concrete slabs. Most applications can hold loads up to 1,000 kg/m², which is much higher than composite applications that don’t rely on stud welding.

Shear Connectors

Shear connectors are the most critical component of a composite construction when bonding concrete and steel beams. They completely impact the effectiveness, ergonomics, speed, stability, and safety of a composite construction. In hindsight of examining bridge collapses, severe road damage, and other failures, we’ve determined that the correct application or use of shear connectors often could have prevented the incident.

Construction Welding

When using shear connector studs in construction welding, drawn arc currents range from 240 to 3,000 amps and a ceramic ferrule is used to prevent issues like splatter, burring, slagging, and brittle welds. Shear studs are typically low-carbon steel, but they can be applied in stainless steel when protection from corrosion is necessary. When welded, the length of a shear connector is reduced by about 5 mm.

Stud Welding in Composite Construction

The reason why the incorporation of stud-welding techniques in composite construction is so effective is because the installed studs resist shear force. Shear force runs parallel to the cross section of a road, bridge, or other composite structure. That impact creates significant strain on inflexible construction, but longitudinal shear connectors allow the concrete and beam composite to bend and resonate with the stress, increasing durability.

Installation of Shear Connectors

The correct installation of shear connectors prevents the concrete slab from separating from the steel beam as they both bend from stress. Shear connectors should be installed on a clean deck surface free of paint, dust, oil, and water. Ceramic ferrules can be left to be covered by the concrete pour, but the pour should significantly cover the tops of the studs. Some beam areas may require additional reinforcing depending on the shallowness of the decking and the region along the composite construction.

There are several types of stud welding utilized in many different industries. Northland Fastening Systems offers a comprehensive supply of welding tools for rent or purchase, studs for all applications, accessories, and the expertise of our own technicians to customers worldwide. Depending on the application, one type of stud welding operation may be better suited than another. When it comes to capacitor discharge (CD) stud welding, there are hundreds of applications that make the fabrication of many products possible. CD stud welding is best suited for smaller-dimension studs and pins. The CD welding process doesn’t leave marks on the opposite side of the weld surface, so it’s ideal for clean results on thin surfaces.

CD Stud Welding

CD stud welding might be more prevalent than many people might realize. It’s used in hundreds of products and tools we use daily, from automotive applications to the installation of home insulation. Some of the lightweight applications of CD stud welding are even more common in most people’s lives. For example:

 

• Cookware: Many pots and pans are assembled using stud welding operations. Various handles, lids, and specialized pots like steamers and pressure cookers are made stronger and longer-lasting with stud weld connections. In the face of heavy-duty commercial cooking, strong stud fastening systems hold up to the extreme heat and stress of an industrial kitchen.

 

• Hardware: There are many different applications for the general category of hardware. From brackets, cleats, and hinges to tool handles and specialty kits, CD stud welding with pins and small-dimension studs is a highly effective fabrication method. Hardware for commercial doors also utilizes CD welding for escutcheon plates and insulators.

 

• Small appliances: While various types of stud welding are used in the manufacturing of many kinds of large appliances, from home ovens and dishwashers to factory-grade food processing equipment, CD welding is also used extensively in building small countertop appliances. This includes most microwaves, deep fryers, hot plates, coffee makers, and more.

 

• Jewelry: Along with soldering and other fine fabrication methods, stud welding is a useful tool for the jewelry industry and jewelry arts. High-quality jewelry is designed to last a long time with frequent use and hold up to routine cleanings. Using stud and pin welding, jewelers and artists can create strong connections between components.

 

• Electrical setups: Because it provides a strong connection with no backside marking, CD welding is ideal for electrical enclosures, circuitry systems, terminals, and more. It’s also heavily used in fabricating devices like pumps, motors, and even communication equipment.

Even for small applications, CD stud welding is one of the most effective light-weight systems for rapid production with little-to-no warping.

From production uses like insulation fasteners to heavy-duty composite construction, stud welding is relied on for many purposes. If you’re working with stud welding in any capacity, Northland Fastening Systems (NFS) has the tools for you. We provide stud welding supplies, including tools for rent or purchase, studs in all dimensions with custom options available, and complete welding accessories. In addition to a comprehensive supply of welding equipment, NFS technicians offer expert advice on all stud welding processes, including the use and setup of CD weld studs for effective and quality results.

CD (capacitor discharge) stud welding is a manufacturing technique that’s useful for some of the smaller dimension pins and studs, like the stainless steel studs used in food grade, lightweight welding, for example. Other common applications of CD weld studs are for insulation fasteners, electrical enclosures, internal electronics, and on-board aerospace systems.

Utilizing CD stud welding operations in the appropriate application is highly beneficial for many reasons. Not only does CD welding create a powerful connection point with no mark-through on the opposite side of the weld surface, it’s a rapid process that conserves energy, improves efficiency, and produces a clean finish when done correctly.

Understanding how to set up CD weld studs for the full welding process is critical for performing an effective operation. A CD stud welding process occurs in five basic steps:

1. Contact of stud tip to weld surface
2. Ignition of weld tool
3. “Placement” or pressuring of stud into surface material
4. Fusion of stud into surface material while both metal are molten from ignition
5. Cooling of both materials to complete the weld connection

Setup can vary depending on the type of tool you’re using, implementation of different collets, stud dimensions, weld surface material, and electrical specifications. In general, the setup process takes the following steps, and in most cases, will get you ready to weld:

1. Set up the assembly of “B” collet and “B” stop accessories by loosening the screws at the tip of the gun shaft to allow the installation of these parts.
2. Ensure the collet is the correct size for stud diameter; then install a correctly paired length of stop into the collet.
3. The collet and stop should seat correctly into the gun (until it stops completely on insert).
4. Insert the stud into the collet until it stops fully. The stud should extend past the end of the collet and be held tightly in the gun during welding.
5. Do not let the stud tip ever come into contact with the collet when the weld is ignited.
6. Place the leg and foot assembly into the gun to allow ⅛” of the stud protruding past the foot.
7. Tighten set screws and ensure the area around the weld point and your welding space is clear.

If you’re just getting into the stud welding world, there may be some terms thrown around that you’re unfamiliar with. When you break down each type of stud welding and the supplies and tools used, there are some nuances that will arise. Whether you’re just starting out or if you’ve been in the stud welding game for years, you can find all your stud welding supplies and technical support with Northland Fastening Systems.

 

The basic terminology of stud welding can be broken into two categories of drawn arc stud welding and capacitor discharge (CD) stud welding. Within these two types of stud welding, there are variations to operations and specialized tools that can be used to get many effects.

 

Drawn Arc Stud Welding

 

1. Drawn arc: These welding tools use both flux and a ceramic ferrule. The flux creates a clean weld zone as the tip of the gun makes contact with the surface material, and the ceramic ferrule contains the molten weld point to prevent splatter. Drawn arc welds using flux and a ferrule create the strongest stud bond.
2. Gas arc: Gas arc welding replaces a ceramic ferrule with inert gas, and it typically does not use a flux to prepare the surface (though some gas arc weld processes still use a flux ball). Gas arcs are used commonly in automated welding operations where precision and speed limit the need for flux. This provides a quick, cost effective weld that saves labor because it does not require chipping off a ferrule when the weld is completed.
3. Short arc: For operations using high currents and requiring fast weld times, short arc welding can be a reliable process. Short arc welds can tend to be weaker or more porous because they do not use flux or ferrule, but in the right application, they can be key.

 

CD Stud Welding

 

1. Contact CD welding: This process places the tip of the stud against the weld surface while the weld occurs. The current vaporizes the tip of the stud and an arc is created between the stud and surface. This arc heats both stud and surface metals, and the molten components are connected.
2. Gap CD welding: Gap welding is a faster process than contact welding. The tip of the stud is poised above the surface as the arc is formed and then pressed against the surface as both become molten.

 

If you are just starting out in the stud welding industry, you can use these terms as a base reference for areas you want to study or try as you learn and become a more professional welder.
