Function of Insulation Installed with CD Weld Studs

Posted on by norfas by norfas

Different insulations have countless uses throughout buildings, vehicles, machinery, and more. Insulation is a critical component in residences, commercial operations, municipal properties, infrastructure, and of course, industrial facilities. Modern insulation technologies are advanced solutions for a broad range of heat, fire, and cold exposures. The insulation systems used in every application are also improving quickly to meet growing demand for passive buildings and net-zero energy operations throughout industries. While insulation can be installed in many ways, from spraying insulation foam to adhering sheeting, a large number of residential, commercial, and industrial insulations are installed with stud welding. CD weld studs and CD welding pins, in particular, are highly useful for fast, clean, and strong installation of various types of insulative materials. If you’re installing insulation with welding pins, you can find all the supplies you need with Northland Fastening Systems (NFS), including tools for rent and purchase, CD studs and pins, and welding accessories. We also offer repairs for most welding models and the advice of our own expert technicians.

CD Weld Studs

Insulation serves multiple purposes, all generally around the control of heat and cold conduction from one area to another. In buildings, insulation is the main component in atmosphere control, preventing indoor temperatures from becoming difficult to regulate. In more complex applications, however, insulation can act as an extreme heat shield for temperatures up to 1,220ºF.

Insulation Function Overview:

  1. Fire proofing: Not only is insulation capable of fire proofing in working environments where sparks, flammable liquids, gasses, dust that could combust, and other high risks of fire are present, it’s also important for home and businesses in general.
  2. Fire stopping: Insulative materials that can withstand temperatures between 300ºF and 1,200ºF are critical fire-stopping solutions. These insulations are made from noncombustible materials and are typically applied between rooms and around building skeletal structures to keep fire from spreading through a building.
  3. Heat containment: For building insulation and general heat containment in large spaces, insulation installed with CD weld studs can cover the environmental control for an entire building.
  4. Heat shield: Smaller insulative heat shields are installed in cars, trucks, planes, trains, and other vehicles operating with combustion engines. These heat shields are also used in most industrial settings where machinery operates at high temperatures.
  5. Cool containment: Like heat containment insulation for a whole building, insulative materials also contain cool air generated by air conditioning. This is especially important for buildings in continually hot climates.
  6. Cool shield: Industrial facilities also often use extremely cold systems like liquid nitrogen. These low-temperature materials can be dangerous to workers and equipment exposed. The use of cool shield panels to insulate against these systems is important.

Summary

In many cases, these insulation systems are installed with stud welding. To learn more about insulation fasteners and other CD weld studs, contact NFS at (651) 730-7770 or request a quote online.

 

 

Technical Aspects of Successful CD Stud Welding

Posted on by norfas by norfas

As a fastening system, stud welding has a versatile range of applications across industries. Not only can larger diameter studs be used in heavy-duty construction, such as the building of infrastructure and skyscrapers, smaller welding pins are important in the role of food safe equipment and insulation. In many regards, the application of stud welding is endless. Compared to other techniques like riveting and bolting, stud welding also has many benefits. However, these weld connection points are only as good as the knowledge and skill of the technicians performing them. If a weld is calibrated incorrectly or positioned at the wrong angle, a connection point can become brittle, too cold for full fusion, or result in unsightly splatter of molten metal. If you’re working with stud weld fastening systems for any application, you can find the tools, studs, and accessories you need with Northland Fastening Systems (NFS). NFS also provides repair services for most models, and we offer expert advice to help you achieve successful welds from drawn arc to CD stud welding.

CD Stud Welding

CD welding is a type of fastening system that typically uses smaller diameter studs. It’s used to install insulation, build electrical enclosures, construct food safe equipment, and even jewelry, signage, and other super small diameter pin fasteners.

Whenever you are installing CD studs and pins, several technical aspects should be taken into account to achieve a successful weld.

  1. Time: In general, CD stud welding is a rapid operation. Welds can be completed as quickly as 0.01 seconds and on welding surfaces as thin as 0.020″ (0.5mm) This fast welding time is one of the many benefits stud fastening systems provide, but if the welding time is done too quickly or with too long of a hold, it can result in an incorrect weld. The time of the weld goes hand in hand with stud penetration.
  2. Penetration: The longer or shorter the time of a weld, the deeper or shallower the penetration. If a weld is done too quickly, the weld penetration will be too shallow. A shallow weld often creates a brittle, easily cracked connection point. Welds that penetrate too deeply can spatter molten metal and provide an unattractive, potentially porous weld.
  3. Temperature: Penetration also intersects with temperature. If a welding tool is calibrated to the wrong power supply, it can result in a weld that is either too hot or too cold. Welds that are too cold will also have inadequate penetration, while a weld that is too hot will result in over-penetration. Both cases are weaker, low-quality, fastening systems.

Summary

Like any other manufacturing operations, stud welding must fall into the correct technical parameters for success. To learn more about the CD stud welding supplies and other stud welding information, contact NFS at (651) 730-7770 or request a quote online.

Advantages of Automated Welding Equipment on a Downstream Production Line

Posted on by norfas by norfas

For fastening sheet metal and other steel parts, no better choice can be made than stud welding. Stud welding operations can quickly install studs in a wide range of diameters and lengths, resulting in connection points stronger than the stud and base material put together. Stud welding also only requires access to one side of a work surface and does not require cutting a hole. Compared to other fastening systems, stud welding is leak proof, making it more resistant to corrosion, and offers a sleeker appearance. In addition to these factors, stud welding has many advantages over other fastening systems, whether it’s used by a welding technician to manually install studs or on an automated downstream production floor. For both manual work and automated applications, Northland Fastening Systems (NFS) has a complete supply of welding equipment, from tools and studs to efficient automation technology.

Welding Equipment

Any downstream production line that already utilizes stud welding or a comparable fastening system that could easily be replaced by studs will find multiple benefits with an automated system. This is especially true for fabricators working with sheet metal and steel parts.

Advantages of Welding Equipment

Some of the many advantages that automated stud welding equipment could offer your production line include:

  • Energy efficiency: Automated systems are programmable to exact tolerances so they can work within the lowest energy parameters possible. Our automated equipment can reduce industrial energy consumption, saving you money and lowering your facility’s carbon footprint.
  • Speed: With a programmable automated system, you will see increased production speeds in two ways. First, because it is controlled to exact degrees, the automated equipment itself will move over a part quickly, some as fast as 60 meters per minute. Second, stud welding operations can be completed as rapidly as 0.01 seconds, making them one of the fastest connector techniques.
  • Reliability: With an automated system, stud welding results have an accuracy of around ± 0.15 mm for steel and ± 0.2 mm for aluminum in most cases. This makes it the most reliable system you can integrate into your production line for fastening techniques.
  • Low maintenance: Most stud welders require little to no rigorous maintenance. Even automated systems that routinely install hundreds of studs only need minimal upkeep. High-quality automated designs will save you time and money, thanks to their low demand for maintenance.
  • Safety: One of the biggest advantages to incorporating an automated system on your downstream production line is worker safety. With a completely self-sufficient operating system running on a controllable software program, workers avoid injury, fatigue, and other risks on the job.

Summary

These are just a few of the many benefits you’ll see when you integrate an automated stud welding system into your production line. To learn more about the automated welding equipment and other tools, studs, and accessories we provide, contact NFS at (651) 730-7770 or request a quote online.
