Creating Seismic Ties and Enclosures with Stud Weld Fastening Systems

Northland Fastening Systems provides a complete range of tools, studs, and accessories used in a broad variety of stud welding applications. From food-grade welding to large-scale construction, different types of stud welding are used across many industries.


For numerous engineering purposes, stud welding is a critical tool for incorporating seismic fastening systems into a construction. From structures as small as electrical enclosures to as large as suspension bridges, stud welding is a key component in forming reliable designs that can hold up to movements caused by shifting ground and weather patterns.


If you’re working on a project that requires the use of stud welding as powerful fastening systems, Northland Fastening Systems has tools for rent or purchase, welding studs in a comprehensive range of dimensions, stud welding accessories, and the expertise of our skilled technicians.


Seismic ties and seismic grade enclosures are highly critical for strong, stable engineering with long-term reliability. The natural shifting of tectonic plates causes micro to macro movements on the earth’s surface, and gradual erosion creates moving topsoil and runoff. In addition to these ground movements, structures also face weather patterns that can include severe winds and temperature changes. These elements create conditions that often require seismic ties and other support systems to be built into a structure using stud weld fastening systems.


Seismic Ties: Any structure in an area with seismic activity needs seismic ties and other support systems to maintain stability. In addition to structural ties, straps, guy-wires, rods, and eye bars, many other seismic design aspects are installed with stud welding operations. These seismic ties and other components allow structures more flexibility in addition to strengthening the stability of inflexible building parts. Because of this, seismic components engineered into a structure and installed with stud welding techniques are critical for integrity in the face of seismic activity and severe weather.


Seismic Enclosures: Stud welding is critical in fabricating clean, reliable electrical enclosures. Because electrical enclosures are widespread in many industrial, commercial, and residential settings, it’s important they meet safety standards and can hold up against any elements they’ll be exposed to. For many areas of the U.S. this means electrical enclosures must be seismic rated. Seismic rated electrical enclosures must meet the following requirements:


  • Full welding in addition to stud welded fastening points is necessary for any seismic enclosure.
  • Heavy-duty enclosure doors are also required in place of the typical single latch door. Powerful stud welding tools can fasten heavy-duty doors with three latches and high-quality hinges that hold up to seismic resonance.
  • Seismic grade mounting hardware should be installed at the enclosure location. If possible, enclosures should be welded to their mount point for long-term strength through repeated seismic exposure.
