NELSON STUD WELDING INC.

About NELSON STUD WELDING INC.

Nelson Stud Welding Inc. is a manufacturer of stud welding equipment and consumables, with a product history that dates to the mid-20th century when the drawn arc stud welding process was developed for high-volume fastening in steel construction and shipbuilding. The company's catalog covers the full stud welding system: power supplies, weld guns, and the consumable components that control arc initiation, stud alignment, and weld quality. 3G Electric supplies Nelson Stud Welding Inc. components globally to plant engineers, maintenance managers, and procurement specialists who maintain or operate stud welding systems.

The product families most commonly specified include Morse taper chucks, Nelson-style collets, stop pins (also called back-up pins), and drawn arc weld studs. Morse taper chucks are machined from copper alloy for electrical conductivity and wear resistance; they hold and guide studs during arc stud welding and are available in sizes such as 1/2 in and 5/8 in stud diameter, with accommodation for stud lengths from 5/8 in to 4 in. Nelson-style collets are similarly copper alloy and are sized for smaller stud diameters, including #10 (5 mm), with stud length ranges from 1/4 in to 2 1/2 in. Stop pins position and support studs during welding and are constructed from metal and phenolic materials; they are available for stud length ranges including 1/4 to 5/8 in and 1 3/4 to 2 1/8 in. Drawn arc weld studs are supplied in fully threaded and partially threaded configurations with collar, in steel, with UNC-2A-RH threads. Examples include CFL fully threaded studs in sizes such as 1/2"-13 x 1" and 3/8"-16 x 2", and CKL partially threaded studs with collar in 3/8"-16 x 1". These studs are used to attach components to steel structures in metal building construction, bridge decking, shipbuilding, and heavy equipment manufacturing.

For technical buyers, the relevant selection criteria are stud diameter, stud length, thread type, and the specific weld gun or chuck interface. Nelson Stud Welding Inc. components are identified by manufacturer part numbers, which allows cross-referencing against existing bills of materials and maintenance spares lists. 3G Electric stocks and sources these components for global delivery, supporting both original equipment builds and aftermarket replacement. The catalog includes consumable wear parts such as chucks, collets, and stop pins, as well as the weld studs themselves, so a single order can cover a scheduled maintenance kit or a production run. Because stud welding performance depends on the fit between the chuck or collet and the stud, and on the stop pin setting the stud height, these components are typically replaced as a set. 3G Electric provides part-number-level identification and specification data to help buyers match the correct Nelson Stud Welding Inc. component to their existing equipment.

Common Applications

• Metal building construction — CFL fully threaded drawn arc weld studs, 1/2"-13 x 1", for attaching components to steel structures
• Bridge decking and infrastructure — CFL fully threaded drawn arc weld studs, 3/8"-16 x 2", for structural steel fastening
• Shipbuilding and heavy equipment manufacturing — CKL partially threaded drawn arc weld studs with collar, 3/8"-16 x 1", for consistent arc positioning
• Stud welding maintenance — Morse taper chucks in 1/2 in and 5/8 in stud diameter for replacing worn chucks on weld guns
• Small-diameter stud welding — Nelson-style collets for #10 (5 mm) studs with lengths from 1/4 in to 2 1/2 in
• Weld height control — Nelson-style stop pins for stud lengths from 1/4 to 5/8 in or 1 3/4 to 2 1/8 in to position studs during welding
