Stud welding is used so prolifically across widely different industries that it often pops up in unexpected applications. Not only is stud welding used extensively in the automotive and construction industries, it’s also effective in building food-grade equipment, electrical enclosures, and even insulation and roofing. No matter how you are utilizing stud welding, you can find the supplies you need at Northland Fastening Systems (NFS). We provide a comprehensive range of welding studs for drawn arc, CD, and short cycle welding with additional options for custom dimensions. NFS also offers welding tools for rent or purchase and stud welding accessories. Our team of expert technicians has the training and skills to help you get whatever tools you need to complete your stud welding process.
Stud welding is a key operation for composite construction, including in building insulation and roofing. When it comes to welding insulation fasteners and roofing components, it’s important to select the right type of stainless steel for the stud welding process you’re working with.
All materials used in welding insulation fasteners must meet the standard guidelines of the American National Standards Institute (ANSI) and the American Welding Society (AWS). Within these standards, stainless steel grades typically approved are 300s in non-magnetic states with basic annealing. This includes 302, 304, 305, 309, 310, and 316. While 304 (also listed as 18/8) and 305 are the most commonly used in typical insulation fastening and roofing component welding, other stainless steel grades in the 300s are beneficial in their own way for certain applications.
Steels in the L series, like 316L, are often the most effective choices when resistance to corrosion is critical. In high heat applications, SS series like 320SS and 330SS are most effective, but for extreme temperatures and refractory applications, super alloys like Inconel 601 are more effective than stainless steels. Stainless steel temperature ranges for the insulation fastener stud welding process vary between 1,400ºF and 2,000ºF, while Inconel is used in applications around 2,200ºF. Steel grades 302, 304, and 305 are best at 1,400ºF applications, and 316 is best at 1,700ºF, 310 is best at 1,850ºF, and 330 is best at 2,000ºF.
No matter what insulation fastener and roof component stud welding process you’re utilizing, choosing the right stainless steel or other material is a requirement. Plan ahead your production schedule with attainability and lead time of acquiring different steels in mind. While many steel types are easy to source, some need to be special ordered with longer lead times.
