Best Cable and Welding Gear Management for Job Site Safety

Posted on by norfas by norfas

Active job sites in any industry should have safety systems, checks, and manufacturing process regulations in place for the protection of workers, construction materials, and equipment. In the stud welding industry, safety is equally important for all those factors, especially because stud welding operations are so prolific across many different types of job sites. From multi-story constructions and major infrastructure to automated in-house production lines, safety systems and precautionary practices are critical. If you are working with stud welding for any project, Northland Fastening Systems can provide the supplies and support you need to get the job done. We offer a broad range of welding gear, which includes tools for rent or purchase, welding studs, accessories, and even repair services.

Safety in the Workplace

Although manufacturing in general has been industrialized since as early as the 1760s, universal safety standards have been slow to develop. In the U.S., OSHA wasn’t established as part of the U.S. Department of Labor until 1970, when the Occupational Safety and Health Act was passed.

Welding Gear

Today, OSHA helps make a broad range of work environments, from offices to construction sites, safer for workers, employers, and third parties. For worksites where stud welding gear is active, OSHA dictates several safety conditions, which include cable management.

The Need and Importance of Cable Management

Stud welding equipment on job sites often needs to be moved far from power sources, requiring cable extensions that can spread across trafficked areas and throughout other equipment and building materials. These cables present several hazards:

  • Tripping hazards, which can lead to more severe fall risks
  • Tangle hazards with other electrical equipment and power tools
  • Electrical issues that arise if a surge occurs or cables are damaged
  • Electrocution risk if cables are damaged from mismanagement
  • Falling object hazards if items are pushed by cable movement
  • Fires or explosions due to sparking from damaged cables
  • Ineffective installation of studs caused by poor power supply to welders

Welding Gear Includes Cables

To prevent any of these safety issues, deliberate cable management is important. Cable management starts with planning the layout of extensions and the movement of cables throughout a job site. Care must be taken to ensure cables will not build up through walkways or stretch underneath other equipment. Always make sure cables and any other electrical systems are properly grounded. Cable ties and links are small but mighty components that can keep cables tidy, in place, and away from areas of a worksite where they might be damaged or cause other problems.

Summary

Cable management and stud welding safety only work with the right equipment. To learn more about the welding gear, supplies, and cable management options we offer, contact Northland Fastening Systems at (651) 730-7770. Request a quote online to get started with us today.

Material Specifications for the Drawn Arc and Capacitor Discharge Stud Welding Process

Posted on by norfas by norfas

Because stud welding is used so prevalently throughout different industries, it shows its versatility in terms of applications and materials. Stud welding operations also have great flexibility when it comes to sizing, such as stud diameters and lengths. With stud welding, you can perform food-grade fastening systems, composite construction, large-scale thru-decking, and much more. If you are taking advantage of the wide range of the stud welding process for any project, big or small, you can find all the supplies you need with Northland Fastening Systems (NFS). We provide a complete supply of welding tools for rent or purchase, drawn arc, capacitor discharge (CD), and short cycle welding studs, welding accessories, and repair services for most models. Our own welding technicians are also available to provide support and advice from their own expertise and knowledge.

Stud Welding

For the majority of stud welding, steel is a mainstay material for drawn arc and CD operations, but there are many other materials that are critical parts of the stud welding process as well as materials that can improve and alter the properties of a weld.

Stud Welding Process

Let’s look at the material specifications for different components of the many steps that may be included in a full welding operation:

Studs and surfaces:

As mentioned, steel is a primary material for most stud welding scenarios. Low carbon steel and 302/304/305 stainless steel grades are common for drawn arc welding. However, for drawn arc operations, aluminum, other stainless steel grades, monel, and inconel can also be used for studs and surfaces. CD stud welding uses similar materials, including low carbon and stainless steel, but 1100, 6061, and 5000 aluminum alloys, brass, and other steels can also be used.

Plating:

For drawn arc welding, cadmium and zinc alloys can be used as plating. CD welding can use copper, cadmium, nickel, zinc, and many other plating metals. If nonweldable plating is already on a surface, that should be removed to prevent weld contamination.

Annealing:

Generally speaking, all low carbon and stainless steels can be annealed for both the stud and surface. Annealing can be done to a maximum of 75 Rockwell B for low carbon steel and 90 Rockwell B for stainless steel.

Ferrules:

An important nonmetal material used in stud welding comes in the form of a ceramic ferrule. Ceramic ferrules are a part of the drawn arc process. Ferrules are installed at the point of the weld around the stud tip to contain and control molten metal while the weld is performed. They can then be chipped off when the weld is cooled.

Using CD Stud Welding to Protect Electrical Equipment from Hazards

Posted on by norfas by norfas

Stud welding is used in the fabrication of many fixtures used in the industrial world, including electrical enclosures. Electrical enclosures are built to protect a variety of devices, circuit boards, switches, relays, motors, and controls. Because electrical enclosures are so prevalently used throughout industries as well as for commercial, residential, and municipal purposes, they are critical structures that have to hold up against many hazardous conditions. Even enclosures that remain indoors need to withstand potential contaminants that could compromise a delicate electrical system. The majority of effective electrical enclosures are built with CD stud welding operations due to the strong, clean, and rapid connection points the process provides. If you are fabricating electrical enclosures with stud welding systems, you can find all the supplies you need at Northland Fastening Systems. We offer a comprehensive supply of stud welding tools for rent or purchase, drawn arc and CD welding studs, welding accessories, and repair services for most models.

CD Stud Welding

Electrical enclosures built with CD stud welding offer several benefits to manufacturers. CD fastening operations are cost-effective and long-lasting, and CD welding connection points can be quickly installed with no marking on the reverse side.

Because there is such a broad range of assemblies that electrical enclosures protect and the locations of enclosures vary so much, they have to be able to face the many hazards they may be exposed to. Some of those hazards include:

Hazards Include

  • Gas: Industrial worksites often have the potential for atmospheric gas exposure. Electrical enclosures on jobsites and other locations operating with chemical gases or vapors must be able to be fully sealed against those contaminants.
  • Dust: Even indoors, dust can be a problem for electronics. Simple electrical enclosures are effective inside, but enclosures that are outside permanently need to be ruggedized to protect against all dust particle sizes.
  • Moisture: In addition to dust, outdoor enclosures need protection from multiple sources of moisture, such as rain, snow, and humidity. Humidity can be a problem in any climate, even in more arid regions.
  • Flame: While electrical enclosures aren’t generally meant to survive a building fire, industrial site enclosures are more prone to being exposed to flames. Because of the greater risk of minor flame exposure on worksites, enclosures need some extreme heat resistance.
  • Temperature: Both extreme cold and heat can negatively affect electronics. To prevent damage in settings where excess heat or cold could be an issue, enclosures should have built-in insulation and seals.
  • Physical stress: Electronics are also susceptible to damage from physical stresses like vibrations, falling objects, resonance, and more. Ruggedized electrical enclosures need specialty impact protection built on the interior and exterior.

Summary

There are many types of electrical enclosures built with CD stud welding that can withstand many types of potential damage. To learn more about our supplies and services, contact Northland Fastening Systems today at (651) 730-7770 or request a quote online.

Inspection and Testing of Thru-Deck Welding with NFS Fastening Systems

Posted on by norfas by norfas

Thru-deck stud welding is an important operation for the construction industry and is utilized in a wide range of composite building processes, including attaching metal deck sheeting to steel beams. Decking and steel beams have widespread use in the construction of many kinds of buildings, infrastructure, and other large structures. Because thru-deck welding is such a critical part of many fabrication projects, it’s important for welds to be performed correctly, and for testing and inspections to follow international standards for quality. If you’re working with thru-deck welding processes, we can help. Northland Fastening Systems (NFS) supplies a comprehensive range of tools for rent or purchase, studs, accessories, repairs for most welding models, and the guidance and knowledge of our own skilled technicians.

Thru-Deck Welding

With thru-deck welding, you’re likely operating on an active job site, which means safety is key. Check your cables, equipment, and power source for safety and to ensure you’re receiving enough power through extended cords; make sure your welding surfaces are grounded to a clean spot on a beam; and check your welding surface for dirt, water, and other contaminants.

Once you’ve made sure your conditions are appropriate for thru-deck weld fastening systems and you’ve performed your weld, you should also test and inspect the weld results before continuing on to complete a series of welds.

Testing

Ideally, you will perform tests on pre-production and production weld results. All testing should follow the American Welding Society Structural Welding Code D1.1. This means accounting for the material and design, fabrication, qualification, and inspection. Many details need to be taken into account with your testing, including not performing a test in cold weather unless the stud has cooled to be warm to the touch. If a stud is hot or cooled completely in temperatures below freezing, it will compromise the results. Learn more about AWS testing standards and more about basic testing of stud welds.

Visual Inspections

Visual inspections are just as important as following the AWS code for thru-deck welding specifications. In your visual inspection, you should be able to see the weld point completely around the stud. Any undercuts, spattering, or other abnormalities at the weld point is a sign of a poor weld. If you can’t see 360 degrees around the weld, you may need to use destructive testing methods. This can be done with a hammer hit or by bending the stud to a 15-degree angle. In most cases, bending will be a more effective test. If the weld fails with either test, you need to recalibrate your conditions and test and inspect a new result.

Thru-deck welding is one of many useful stud weld fastening systems for the construction industry. For more information about our supplies for thru-deck and other welding operations, contact NFS at (651) 730-7770 or request a quote online

Selecting Ferrules to Pair with Your Stud Welding Products

Posted on by norfas by norfas

Three main kinds of stud welding operations are utilized in a range of industries. Capacitor discharge (CD) welding is useful for rapid, clean operations with thinner diameter studs and pins. Common applications of CD stud welding include insulation installment, electrical enclosures, and food service equipment. Another operation, drawn arc stud welding, can be used for larger diameter fasteners. Drawn arc studs are used in heavy-duty construction projects like bridges, roadways, and multistory buildings. Short cycle welding is the third type of stud welding operation used across industries. Essentially a drawn arc process, short cycle welding can be automated more easily, performed faster, and done on uneven or coated surfaces. No matter what kind of welding operations you use, you can find all the stud welding products you need at Northland Fastening Systems (NFS). We supply a comprehensive range of welding tools for rent or purchase, drawn arc and CD welding studs, welding accessories, repairs for most models, and the expert advice of our own technicians.

Ceramic Ferrule

In most cases, drawn arc stud welding will utilize a ceramic ferrule placed at the point of the weld. Ferrules help control the weld by containing molten metal and providing some temperature regulations. However, because drawn arc welding can be done on many kinds of surfaces—including at various angles, for different profiles, and with a broad range of dimensions—there is an equally diverse selection of ferrules you can choose from. Picking the right ferrule depends on the conditions of your weld.

 Stud Welding Products

There are 10 standard ceramic ferrule stud welding products you can choose from, including:

  1.  Flat and flat heavy-duty: These ferrules are used with down-hand operations and can be paired with headed studs, deformed bars, fully threaded studs, and in vertical applications with studs under ⅜” diameter.
  2. Collar: These are used with collar studs, studs with short applications, or low-profile studs.
  3. Reduced base: Studs with reduced bases, such as ones with unthreaded sections at the tip, work best with reduced base ferrules.
  4. Pitch: These are used with partially threaded studs to accommodate the pitch in diameter from the wider threaded portion to the slimmer unthreaded portion.
  5. Thru-deck: Thru-deck welding is a common construction operation, and it requires thru-deck ferrules. These are most useful in composite construction with steel and concrete.
  6. Thru-deck wired: Similar to thru-deck ferrules, these are used with ¾” stud diameters that can be installed in rapid operations.
  7. Angle: When studs need to be installed at an angle, these ferrules can be utilized with inside or outside angle positioning.
  8. Vertical: Studs can be installed on vertical surfaces, but the operation needs to use a vertical ferrule to contain the molten metal and prevent drips.
  9. Flat heavy-duty special: Special ferrules have finer teeth at their base, which helps with ½” vertical applications and the installation of deformed bar anchors.

Sheet Metal Fabrication for Construction Welding with Studs

Posted on by norfas by norfas

Metal working and, in particular, constructing tools and equipment with metals is a practice dating back to the Bronze and Iron Ages. The Bronze Age began in about 3300 BCE and led into the Iron Age around 1200 BCE. Over thousands of years, our understanding of metals and the application of different metal objects expanded greatly. Even in the last 50 years, scientific research and development of high-performance metal alloys has advanced significantly, including improvements to sheet metal. Today, many industries are reliant on sheet metal for the fabrication of countless tools and equipment. Some of our largest global industries completely rely on the production of high-quality, specialized sheet metals for manufacturing. For example, the automotive, aerospace, railroad, oil, electronics, food, medical, computer, military, agricultural, and construction industries would be unable to operate without access to sheet metals. Within the majority of those industries, construction welding is used to apply studs and build with sheet metals for strong, clean fastening systems. At Northland Fastening Systems (NFS), one of the main industries we supply with studs, tools, accessories, and other equipment is the sheet metal welding industry.

Studs Attached With Construction Welding

Structural steel building with sheet metals includes several steps on the production line, including cutting, bending, assembling, and more. Stud welding fasteners are an important part of the fabrication process. Studs attached with construction welding have a strong bond to sheet metal surfaces; they offer a clean, mark-free finish, and they are an affordable, efficient fastener option.

Grades of Sheet Metal

Stud welding can be used in all kinds of applications with any grade of sheet metal. While there are many kinds of sheet metals available today three main categories of all sheeting still remain: commercial, industrial, and structural.

  1. Commercial metal sheeting is used to build a wide range of products marketed to individual consumers and businesses. Common examples of products made with commercial metal sheeting include appliances, electronics, and cars. Commercial metal sheeting is so prevalent across industries that almost every household and business will use a product made with stud welding sheeting daily.
  2. Industrial metal sheeting is used to manufacture parts that can be integrated into other products down the line. Manufacturers are the main purchasers of industrial sheeting, and they typically use that material to make parts for tools like bandsaws, drill presses, hydraulic systems, and more.
  3. Structural steel sheeting is used in the construction welding industry. Sheeting installed in buildings and infrastructure like skyscrapers, bridges, water towers, shops, factories, and even homes are all structural metals. Stud welding is used throughout many construction welding processes.
