Building Class A Crafts to Small Research Vessels and Other Small Boats with Stud Fastening Systems

Posted on by norfas by norfas

Stud welding is a widespread manufacturing operation today thanks to the powerful, fast, versatile, and clean results it provides. The first uses of stud applications with drawn arc welding began in the shipbuilding industry. During WWI, the rapidly increasing demand for military and seaworthy ships gave rise to the development of better stud welding technology. Using stud weld operations to perform strong, water-tight connections, the US Navy and industrial marine fabricators could meet the need for war-worthy vessels. After WWI, stud welding continued to be used in building vessels for military, commercial, industrial, and consumer use. During WWII, stud welding was again relied upon for shipbuilding, but also expanded as a manufacturing operation to the fabrication of other vehicles, containers, electrical systems, and more. With advancements in electrical technology, material design and processing, and automated systems since the end of WWII, stud weld fastening systems can be used to install connection points as thin as a 10-gauge pin to as thick as a 1” diameter shear connector stud. Whether you’re working small or large, you can find all the supplies you need with Northland Fastening Systems. Not only do we offer tools, studs, and accessories; we also provide repairs and the expert advice of our own welding technicians.

Fastening Systems

Although stud fastening systems have spread to so many industries today, those operations are still used frequently in the shipbuilding industry to manufacture a broad range of vessels. In addition to freighters, large military ships, and commercial liners, stud welding is also used in the production of small boats.

The US Office of Marine & Aviation Operations classifies small boats into five categories by length, weight, and usage. Those categories include:

Class A:

Boats that are shorter than 16 feet long overall fall into the Class A category. This generally includes small motorboats, daysailers and other small sailboats, dinghies, transport boats, and small fishing vessels.

Class I:

Vessels between 16 and 26 feet long are considered Class I boats. This can include boats with small sleeping cockpits like short haul fishers, camping cruisers, small racers, park ranger vessels, and small speedboats.

Class II:

Similar to Class I, Class II vessels include slightly longer haul fishers, longer distance racing sailboats, multi-bed cockpit sailers, and other fast motorboats. Class II vessels are between 26 to 40 feet long, so small cruise ships, yachts, and science vessels can be rated within that range.

Class III:

Class III vessels are between 40 and 65 feet long, generally including larger fishing operations, tugboats, small industrial crafts, ferries and other transport, grander yachts, police and fire department cruisers, and historical ships.

Small Research Vessels:

These vessels may be larger than 65 feet in length, but no heavier than 300 gross tons. SRV are used in short-term research projects or in close vicinity to labs and testing centers.

In today’s world, many small vessels and ships are manufactured with stud fastening systems. To learn more, contact Northland Fastening Systems at (651) 730-7770, or request a quote online today.

Food Grade Welding Eliminates Harborage

Posted on by norfas by norfas

Not only is stud welding a key operation for the construction industry, including composite construction with shear connectors in bridges, roads, and other infrastructure, it’s also utilized on smaller manufacturing scales for equipment like electrical enclosures, food grade instruments, and commercial kitchen appliances. In the food industry, stud welding serves an important purpose when it comes to manufacturing factory processing systems and equipment. Because stud welding creates clean results and strong welds without marking through on the reverse surface, it can be used to build smooth surfaces with full wash-down capabilities. If you’re working with food grade welding for the production of food industry or commercial food equipment, Northland Fastening Systems has the supplies you need for drawn arc, capacitor discharge (CD), and short cycle welding. We provide tools for rent and purchase, studs in a complete range of dimensions with custom options available, welding accessories, automation support, the advice of our own skilled technicians, and services and repairs for most models.

Food Grade Welding Makes Equipment Easier to Clean

Food grade welding with studs makes equipment easier to clean, helping commercial kitchens and food production facilities maintain sanitation practices and support good hygiene. Food products made on an industrial scale can be one of the main sources of foodborne illness epidemics. To eliminate the risk of food contamination, stud welding reduces the potential of harborage.

What is Harborage?

In the food industry, harborage occurs when particles are trapped in crevices, bends, and other hard-to-clean nooks and crannies in equipment. Not only does this introduce rotting or pathogenic food particles that can damage the integrity of other products; it can also increase the risk of rodents and insects in a facility. Stud welding reduces harborage by removing the crevices potentially left by other types of fastening systems.

Connection Points are Clean

Stud welding connection points are clean, smooth, and fully fused. Food grade stud welding processes also use antiseptic stainless-steel surfaces that resist corrosion or oxidation. With most designs, stud welding engineering can also reduce external angles and corners, eliminate risks of overstressed surfaces, and fully seal connection points from microscopic pitting.

Where Can Harborage Occur?

Harborage can occur in equipment that is not manufactured to the highest food safety standards in several areas, including control panels, equipment legs, cracks, crevices, hardware, moving parts, HVAC equipment, multiple surface types, and any wet areas. To fully remove problems with harborage in these areas, stud welding systems should be installed whenever possible.

Full Wash Down

With a tight connection point and no crevices, zero marks on the opposite side of the weld surface, low-stress surfaces, and corrosion-resistant materials that are compatible with full wash down capabilities, food grade welding can significantly reduce the risk of harborage in industrial processing and commercial kitchens.

Installing Climate Control Technology and Other Uses of Construction Welding

Posted on by norfas by norfas

Stud welding is used in many aspects of the building construction processes, from structural steel fabrication and sheet metal building to the installation of insulators, HVAC systems, and other types of climate control technology. If you live in a home built later than the 1950s, it’s likely that stud welding was used in some portion of its construction. Not only is stud welding used in installing insulation, fire protection, ducting, and other climate control building materials; it’s also used to integrate sound proofing in many areas of residential, commercial, and industrial buildings. If you’re building with stud welding operations, Northland Fastening Systems has the tools and supplies you need to get the job done correctly and economically. We provide a complete range of drawn arc and CD (capacitor discharge) studs, tools for rent or purchase, welding accessories, and the advice of our expert technicians. NFS also provides quick, long-lasting repairs and services for customers working with all kinds of construction welding for stud installation.

Construction Welding

Though drawn arc stud welding and most CD construction welding operations use studs with diameters wider than 4-40 (0.112 base diameter), some CD welding applications are used to install thin pins through insulative materials. This CD pin installation technology allows technicians to quickly attach insulation in multiple construction scenarios with strong connection points.

CD Pins

Some forms of insulation that are installed with CD pins include:

  • Building insulation sheets that cover the interior of walls, flooring, and roofs to keep indoor temperatures at comfortable levels without excessive energy expenditure
  • Heat and cold insulation protectors around heating, ventilation, and air conditioning (HVAC) ducting
  • Insulating containers around air conditioning units
  • Industrial heat exchangers used in many manufacturing industries
  • Cooling systems for factories
  • Climate-controlled storage warehouses and refrigerated or frozen shipping containers
  • Coolrooms in industrial settings, storage, or transportation providers
  • Fireproofing for residential, commercial, and industrial buildings, including spark-proofing in electrical enclosures, heat-proof plating in machinery, and more
  • Heavy-duty heat proofing and fire protection in power plants, incinerators and industrial furnaces, forges, refineries, and industrial buildings processing chemicals and petrochemicals
  • Cabin, sound, fire, and HVAC insulation on freighters, military vessels, cruise ships, and other large ships

Sound Proofing

Sound proofing insulators are also installed with larger CD and drawn arc studs. Sound proofing is important in the entertainment industry for recording studios, live venues, and movie theaters.

High-Integrity Thin-Gauge Connection Points with CD Stud Welding

Posted on by norfas by norfas

Early electrical capacitors date back as far as the mid-1700s. Those early rudimentary electrical charge storage systems developed over the next 250 years to the capacitors we use in many applications today. There are multiple variations of capacitors and supercapacitors used across contemporary industries that are highly advanced storage and release systems. Capacitor discharge technology is also utilized in stud welding applications for versatile, strong welds with thin base material. If you’re utilizing capacitor discharge (CD) stud welding systems, Northland Fastening Systems (NFS) has a comprehensive range of welding supplies, including tools for rent and purchase, studs in a range of dimensions with custom options available, welding accessories, and the technical support of our knowledgeable staff. There are many benefits that CD stud welding provides to manufacturers and technicians working with specific materials and small diameter studs.

CD Stud Welding

Not only does CD stud welding allow technicians to build with small diameter studs as, it’s also a manufacturing technique that allows work on thin-gauge welding surfaces without distortion. The ability to weld extremely small diameter studs onto thin surfaces without risking mark-through or structural distortion allows welders to install fasteners for a broad range of industries, including food-grade equipment and insulation. These processes help manufacturers build with integrity and meet specifications for unique products.

Dissimilar Metals

CD stud welding can also be used to fasten dissimilar metals like various steel grades, aluminum, copper, brass, and other alloys without compromising the strength of the weld surface or stud. This is because CD installation penetrates at shallow depths that don’t risk metallurgical issues.

With an ignition tip that is charged with the release of electrical current from a capacitor, CD tools generate a rapid weld with a clean, ideal cosmetic result. The process of CD stud welding done properly will have little-to-no burn marks, no marking on the backside of the weld surface, and a connection point even stronger than the stud itself.

Automated Production

When working with smaller diameter studs and thin welding surfaces, CD stud welding is also the most cost-effective for labor, materials, assembly, and energy in addition to being the most visually appealing. For components that can be installed in automated production lines, CD stud welding offers a rapid operation with precision on repeat.

High-Integrity Weld

CD stud welding creates such a high-integrity weld because of an exact calibration of heat and pressure. When the capacitor discharges its stored current and activates the ignition tip, the stud is heated and pressed into the weld surface at a specific pressure. The heat and pressure requirements depend on the diameter of the stud and the materials used. While contact CD stud welding is a more common process, some manufacturers will use gap welding tools. Gap welding is an effective operation when technicians who are working with aluminum and stainless steel require a completely mark-free back side.

Technical Details: CD Welding

Posted on by norfas by norfas

The vast majority of industrial manufacturing processes are highly regulated and standardized in today’s technologically advanced world. The International Organization for Standardization (ISO) and many other regulators have established global guidelines that inform manufacturers, distributors, and customers of the quality of available goods and services. ISO approval registrations aren’t an industry requirement, but without a certificate appropriate to a company’s products, management systems, or practices, trusted customers and partners will be difficult to obtain. Northland Fastening Systems (NFS) follows ISO 9001 certificate regulations for the stud welding industry. As a provider of complete stud welding supplies, we understand the importance of quality parts, tools, and other products as well as standardized services. We offer stud welding supplies for drawn arc, short cycle, and CD welding, including tools for rent or purchase, a full variety of studs, and welding accessories. Our customers also benefit from tool repairs and servicing.

CD Welding

Whatever kind of welding operation you use, there are technical details and specifications that are critical to know and follow. For CD welding, in particular, technical details direct everything from the stud requirements to onsite welding conditions. Some basic CD specifications include:

Studs:

CD studs come in a variety of dimensions that are generally smaller than drawn arc welding studs. CD stud welding utilizes smaller dimension studs, pins, and other fasteners for quick, clean connections that will handle lighter shear loads than drawn arc welds, but meet requirements for food grade equipment, one-sided marking, and rapid operations. Studs come threaded internally or externally, and with partial to full thread specifications. Studs can also be flanged.

Materials:

CD stud welding does not require the use of ceramic ferrules, fluxes, or shielding gas. The weld is completed with an exact calibration of capacitor discharge generated heat and welding gun pressure. Studs are made from mild steel, stainless steel, aluminum, or brass. They can be plated with copper, nickel, zinc, or other materials for various applications. CD studs can also be annealed when required.

Automation:

Because the process doesn’t need to use shielding gas or ferrules and because CD stud welding is a rapid, clean operation that results in a strong weld, it’s ideal for automation. CD studs can be loaded quickly and easily into auto feed systems and equipment controlled robotically through CNC software programs. They can also be loaded into a handheld auto feed gun.

Welding conditions:

CD stud welding requires relatively exact conditions for the successful installation of connectors. The tool, power supply, and other equipment need to be capable of welding the diameter, length, and material of your studs. The weld surface should be clean, free from lubricants or dust, and without imperfections like excessive roughness. The tip size, stud diameter, and angle of the tool must also be applied correctly for a good weld.

Technical Details: Drawn Arc Welding

Posted on by norfas by norfas

Stud welding operations today are highly standardized manufacturing processes. They are widespread across multiple industries as fastening systems, in composite construction, for large-scale construction, food-grade fabrication, and more. If you’re manufacturing in the automotive, building construction, sheet metal fabrication, electronics, food service equipment, fabrication equipment, structural steel, or many other industries, you’ll likely use stud welding systems at some point in the production process. For any drawn arc, capacitor discharge (CD), or short cycle stud welding operations, Northland Fastening Systems has the tools for rent or purchase, studs in a complete range of dimensions, welding accessories, and other supplies welders need to get the job done. For drawn arc welding, NFS provides supplies meeting all technical requirements and weld specifications necessary for a variety of applications.

Drawn Arc Welding

Drawn arc processes are a type of resistance welding, and for stud welding operations, they often utilize ceramic ferrules, fluxes, and shielding gas. From stud specifications to tensile load strengths, some standard drawn arc welding technical details include:

Studs:

Drawn arc studs can be threaded or unthreaded, including various kinds of internal and external threads. Stud lengths are indicated as L in terms of BW (before weld) and AW (after weld). AW lengths will be shorter to various degrees depending on stud dimensions. Dimensions range depending on the type of stud, including threaded connectors, bar anchors, shear connectors, and headed anchors.

Ferrules:

Ceramic ferrules are used to contain molten stud and surface materials at the point of the weld vary in dimensions. The ferrules you pair with your studs should match sizing and meet ISO ferrule standards. A ferrule should be able to be cracked off and removed from the weld point when it has cooled.

Materials:

Drawn arc stud welding materials are generally grades of low carbon steel and stainless-steel meeting AWS and ASTM Some studs are plated in zinc, nickel, or copper. Drawn arc studs can also be annealed to Rockwell B Hardness of 75-85.

Shielding gas and flux:

Semi-inert gases like argon, helium, nitrogen, carbon dioxide, and hydrogen in various compositions protect the weld point from exposure to oxygen and water vapor that can contaminate the weld. Fluxes can also be used to generate carbon dioxide shielding gas and regulate melt temperatures.

Tensile and torque strengths:

Standard arc weld stud tensile load and torque strength ranges are based on stud diameter, threads per inch, mean effective thread area (META), tensile load pounds, tensile stress in pounds per square inch, and torque in inch pounds. In practical applications, studs shouldn’t be installed at their maximum yield load. Instead, a safety range of no more than 60% of a yield strength should be utilized.

Accessories:

In addition to flux, ferrules, and shielding gas, drawn arc accessories include adjustable chucks, cable connectors, headed chucks, ferrule foot plates, and cable lugs.

If you’re working with stud welding in any capacity, Northland Fastening Systems (NFS) offers a complete range of welding tools for rent or purchase, studs for drawn arc, capacitor discharge (CD), and short cycle welding, and welding accessories. While we offer equipment that can be integrated into an automated production line, we also have machines for off-site welding jobs when portability and easy setup is most important. Our HBS VISAR 650, for example, is an excellent stud welding machine for times when technicians only have access to low power electrical sources.

Stud Welding Machine

The VISAR 650 is a small, efficient machine for drawn arc welding with ceramic ferrules. It can handle mild and stainless steel studs. It has a welding current maximum of 650 A and a minimum of 100 A. Because it can perform these welding with only 100-240 V, single-phase power sources, it’s an ideal stud welding machine for working on multiple job sites that have the electrical setups of typical residential and commercial properties. The primary plug of the VISAR 650 is also a standard electrical two-prong grounded safety plug that fits universally into outlets.

VISAR 650

For stud welding on projects in the field, the VISAR 650 has two main benefits for technicians working on different job sites:

  1. The VISAR 650 is simple. It’s a tool that’s easy to learn, quick to set up, and simple to carry from site to site. Its intuitive operation makes it the perfect tool for welders that are trained in many different construction technologies or for welders who only use stud welding processes for specific building requirements. It also has a quick storage system for tidying the tool cable built into the machine handle.
