General Applications of Drawn Arc and CD Stud Welding

Posted on by norfas by norfas

Stud welding is one of the most versatile manufacturing operations for small to large scale construction. Though it was originally developed for use in shipbuilding of various types of vessels, it has grown in application to be used in many manufacturing industries worldwide. Its use in so many industries has helped to streamline and speed up the production process while improving the quality and long-term reliability of components and full assemblies.

 

If you are using stud welding in your fabrication processes, Northland Fastening Systems is your one-stop-shop for all the tools, studs, and accessories you need to get the job done. Our team of experts can guide you through the process of selecting the right specifications of studs, welding units, and any other items needed.

 

Because stud welding is such a versatile operation providing a connection point between two metals that is stronger than the metals themselves, it is used in an increasingly wide range of applications. Broadly speaking, these applications include the following:

 

  • Structural Construction: This includes buildings, bridges, water towers, elevators, mining structures, tunnels, overpasses, facades, highways, window frames, doors, and much more.
  • Automotive Construction: Stud welding is used extensively in the construction of all types of vehicles including passenger cars, trucks, SUVs, recreational vehicles, transport vehicles, fork trucks, military vehicles, motorcycles, aircraft, farm machinery, trains, cable cars, excavation vehicles, and much more.
  • Shipbuilding: Many components of ships of all types are fabricated using stud welding. This includes flooring, ceilings, walkways, kitchens, exterior hulling, lifeboats, insulation, food prep stations, and more.
  • Sheet Metal Construction: Various cabinets, enclosures, and other sheet metal products are made using stud welding for clean connection points with no reverse side marking. This includes electrical enclosures, signs, deposit boxes, mail containers, hinges, hand tools, grills, office products, and more.
  • Appliance Construction: Domestic and commercial appliances are also made using stud welding operations. This includes ovens, stoves, refrigerators, ranges, dishwashers, dryers, stereos, financial processors, vending machines, freezers, ice machines, cookware, and much more.
  • Climate Control System Construction: Components of quality HVAC and other climate control systems are also fabricated using stud welding including ducts, vents, dehumidifiers, fans, insulation, and more.
  • Sound-Proofing Construction: The construction of soundproof rooms and systems with stud welding are key to a wide range of applications. This includes recording booths, equipment testing rooms, ducting, building facades, roads, and more.
  • Power Generator Construction: Any type of energy generator needs a specialized system to isolate and transmit that power. Stud welding is key in the fabrication of transformers, reactors, boilers, nuclear systems, steam generators, coal systems, refractories, incinerators, and more.

 

Stud welding is also useful in the installation of insulation against heat, cold, fire, weather, and other harsh elements for a wide range of structures and objects.

Troubleshooting Connection Points for CD Stud Welding

Posted on by norfas by norfas

While CD stud welding is a fairly simple process to the outside observer, the science, physics, and engineering behind it are complex. Very specific temperatures and times must be applied to the stud and weld surface for a connection point to be successful. When performed correctly, in fact, a CD stud weld connection point will be stronger than the stud itself. To help you get the job done quickly and efficiently with quality results, Northland Fastening Systems (NFS) provides comprehensive stud welding supplies and services, including welding studs of varying dimensions and thread sizing, stud welding tools for rent and purchase, and a variety of welding accessories for CD stud welding.

 

NFS technical service and stud welding tool manufacturers provide rich information about the calibration of stud weld equipment and the pairing of welding materials. However, if you are having difficulties calibrating your equipment and are seeing poor results, there are basic troubleshooting procedures you can easily perform.

 

For example, troubleshooting a poor weld connection starts with testing for weld failure.

 

Weld Failure

A successful stud weld connection point is stronger than the stud itself. Because of this, placing stress on both the stud and connection point at the same time to the point of failure can tell you the condition and accuracy of the weld. Ideally, the stud will fail before the weld point because it should be weaker (as seen at 2:18 in our demonstration of the HBS Visar 650). If the weld connection fails at all, the weld connection was unsuccessful. This failure could occur for several reasons, including:

 

  • Cold Weld: CD stud welding procedures have to meet a specific temperature and that temperature has to be applied for a specific period of time. The temperatures and times vary depending on the size and material of the stud as well as the weld surface material. It becomes very clear, however, that a weld was too cold (too low of a temperature, too short of a weld time, or both) if it fails in a stress test. Visually, you can also see if a weld was too cold if the melted area around the stud isn’t an acceptable 360º deep radius.

 

  • Hot Weld: A weld connection point can also fail because of a hot weld if the time or temperature are applied in excess (or if excess heat is applied very quickly). The most obvious sign of a hot weld is a burn-through, which manifests as any distortion to the reverse side of the base material. Even the slightest distortion can compromise the quality of a weld. Another sign of less dramatic hot welds is the splash size of the stud around its base at the weld point. A wide or messy splash of cooled molten metal are a common sign of a hot weld that will fail under stress.
