Application of Different Metals for Welding Studs

Welding is one of the oldest metalworking techniques we still use today. Forge welding dates back to the Iron Age, around 1200 BCE. Since then, many kinds of welding have been developed, and each effective welding operation used across many industries today is highly precise, versatile, and reliable. Stud welding is one of those operations that’s used to install fastening systems, composite construction, and other fabrication techniques. If you are utilizing drawn arc, capacitor discharge (CD), or short cycle stud welding, Northland Fastening Systems has the supplies you need. We also offer a comprehensive range of stud welding tools for rent or purchase, welding studs in varying dimensions with custom options available, welding accessories, and the expertise of our own stud welding technicians. Additionally, we provide repairs and services for the majority of stud welding equipment models, including HBS, Tru-Weld, ProWeld, Nelson, and more.

Uses for Stud Welding

No matter what type of stud welding operation you are using, there is likely a plethora of applications. Stud welding is frequently used in sheet metal construction, food-grade welding, electrical enclosures, composite construction, and more. Its range of uses is in part due to the versatility of the welding operations themselves, but also because there are multiple metals that are conducive to the stud welding process.

Metals Used With Welding Studs

Both the welding studs and the surface material can be made from a range of metals, including:

  • Steel: The most prevalently used metal for stud welding is steel. Low, medium, and high-carbon steel can always be used in stud welding operations. This is also the case for stainless steels, but other steel alloys should generally be avoided in stud welding processes. Low-carbon steels do not require pre-heating, but medium- and high-carbon surfaces (anything above 0.25% carbon by weight) do need pre-heat treatment to prevent cracking.
  • Aluminum: Secondary to steel, aluminum and aluminum alloys are also effective materials for welding studs and surface materials. While alloys are useful, pure aluminum is generally the more preferable material for stud welding.
  • Brass: If lead-free, brass can also be used as a stud welding material. In situations when steel or aluminum cannot be applied for various reasons, brass is usually the alternative material. CD welding operations are most suitable when using brass studs and surfaces.
  • Copper: In some circumstances, copper has great advantages as a welding material. Copper is usually used with CD stud welding when a project needs to be mark-free or when electrical conduction is a factor. For mark-free copper surfaces, brass studs are the best pairing and installation should be performed with rapid CD operations.

While stud welding is relatively limited to these four base materials, there’s a huge range of alloys and types within these different metals. With the right application, stud fastening systems are extremely strong, long-lasting, and flexible.
