    Stud Welders

    Join threaded studs and pins to metal surfaces in milliseconds, forming bonds stronger than the studs themselves. Just load a stud into the gun, aim it against your base material, and pull the trigger to fuse the two together.
    Unlike drawn arc stud welders, our capacitor discharge systems work with metals less than a millimeter thick. They won’t leave fastener heads on the opposite side of the base material, so they’re often used for jobs requiring a clean-looking finish, such as attaching handles to high-end cookware. The one-sided welds are also preferred by the USDA for fabricating dairy tanks and other food-safe machinery – with no holes drilled, germs have nowhere to hide.

    Copper-Plated Steel—Copper-plated steel studs have good corrosion resistance.
    18-8 Stainless Steel—18-8 stainless steel studs are more corrosion resistant than copper-plated steel studs.
    Aluminum—Aluminum studs are more lightweight than steel or stainless steel studs. They’re nonmagnetic. In wet environments, they resist corrosion.
