Nelson Stud Welders

Nelson stud welders support multiple types of stud welding processes, including Capacitor Discharge (CD) and Drawn Arc (DA) welding. CD welding is ideal for smaller diameter fasteners and thin base metals, while DA welding is suitable for larger diameter fasteners and thicker base metals.

Nelson stud welders are widely used in various industries such as construction, shipbuilding, automotive, and manufacturing. They are utilised for attaching metal fasteners to base metals, with applications ranging from building structural components to assembling automotive parts​.

The power requirement for stud welding depends on the process and the size of the studs. Capacitor Discharge (CD) welders typically need 110VAC, whereas Arc Stud Welders require between 230-460VAC, depending on the specific model and application​.

Stud welding offers numerous benefits including stronger welds, elimination of secondary operations (like drilling and tapping), faster production times, and cleaner weld aesthetics. It also ensures uniformity and repeatability in weld quality, making it a preferred method in many industrial applications​.

CD (Capacitor Discharge) stud welding is used for welding smaller diameter studs to thin base metals, creating welds without any reverse side marking. DA (Drawn Arc) stud welding, on the other hand, is used for larger diameter studs and thicker base metals, providing stronger welds but requiring more power and longer weld cycles​.

Stud welding should not be performed when the base metal temperature is below 0°F. Environmental conditions can affect the welding process, so it's important to ensure proper conditions to achieve optimal weld quality​.
