NELSON STUD WELDING INC.

Nelson Stud Welding Inc. is a manufacturer of stud welding consumables and equipment, with a product line that includes weld studs, chucks, collets, ferrule grips, and stop pins. The company's components are designed for drawn arc and capacitor discharge stud welding processes, serving applications in construction, shipbuilding, industrial fabrication, and infrastructure. Nelson's product range covers a variety of stud diameters, lengths, and thread types, including partially threaded drawn arc weld studs with collars (e.g., CKL series in steel with UNC-2A-RH threads) and Nelson-style collets and chucks made from copper alloy for electrical conductivity and durability. The company also produces back-up pins (stop pins) in metal/phenolic construction for precise stud length control, and ferrule grips in copper alloy with small foot sizes for standard stud welding. Nelson components are specified by part numbers such as the 500-001-357 chuck for #8 stud diameters and the 101-015-860-G1000 weld stud pack. 3G Electric supplies Nelson Stud Welding Inc. consumables globally, offering a range of chucks, collets, ferrule grips, and weld studs to support maintenance and production operations. The inventory includes Morse taper chucks for stud diameters from 1/4 in to 1/2 in and stud lengths up to 4 in, as well as standard ferrule grips in nominal sizes like 3/8 in. These components are used in stud welding systems where repeatable arc initiation and consistent weld quality are required. Nelson's products are designed to meet dimensional standards for interchangeability with existing stud welding equipment, and the materials—copper alloy for current-carrying parts and metal/phenolic for wear-resistant stops—are selected for thermal and mechanical performance under welding conditions. For procurement specialists and plant engineers, Nelson components offer defined specifications for stud diameter, length, and thread compatibility, enabling direct replacement in existing tooling setups.

Common Applications

  • Shipbuilding — Nelson drawn arc weld studs (e.g., 101-015-860-G1000) for securing insulation and cable trays to steel decks.
  • Structural steel fabrication — Nelson Morse taper chucks (e.g., 500-001-014) for automated stud welding of shear connectors on composite beams.
  • Industrial maintenance — Nelson back-up pins (e.g., 500-017-019) for replacement in stud welding guns during repair of boiler tube anchors.
  • Infrastructure construction — Nelson ferrule grips (e.g., 501-001-007) for welding studs to bridge deck panels for concrete shear connection.
  • Power generation — Nelson collets (e.g., 500-001-357) for precision stud welding of refractory anchors in furnace linings.

Frequently asked questions

Common questions about NELSON STUD WELDING INC. from 3G Electric.

What materials are used in Nelson Stud Welding Inc. chucks and collets?

Nelson chucks and collets, such as the 500-001-357 chuck for #8 stud diameters and the 500-001-009 chuck for 5/16 in stud diameters, are manufactured from copper alloy. This material provides electrical conductivity for arc initiation and thermal resistance during the welding cycle. The copper alloy construction also offers mechanical durability for repeated clamping and release of weld studs.

What stud lengths are compatible with Nelson back-up pins like the 500-017-019?

The Nelson back-up pin (stop pin) model 500-017-019 is designed for stud lengths from 1 1/4 in to 1 5/8 in. The 500-017-018 variant accommodates stud lengths from 3/4 in to 1 1/8 in. These metal/phenolic pins are used to set the plunge depth and ensure consistent stud projection during drawn arc welding.

Are Nelson Morse taper chucks available for different stud diameters?

Yes, Nelson Morse taper chucks are offered for multiple stud diameters. For example, the 500-001-007 chuck fits 1/4 in stud diameters, the 500-001-009 fits 5/16 in stud diameters, and the 500-001-014 fits 1/2 in stud diameters. These chucks accommodate stud lengths from 1/4 in to 4 in, depending on the model.

What thread type is used on Nelson partially threaded drawn arc weld studs?

Nelson partially threaded drawn arc weld studs with collar, such as the 101-015-860-G1000 (3/8"-16 x 1", steel), feature a UNC-2A-RH thread type. This is a unified coarse thread with a Class 2A fit and right-hand orientation, suitable for standard nut and fastener compatibility.

What is the nominal size of Nelson standard ferrule grips?

Nelson standard ferrule grips, like the 501-001-007, have a nominal size of 3/8 in. These grips are made from copper alloy and feature a small foot size, designed to hold ceramic ferrules in place during stud welding to contain the weld pool and shape the flash.

Does 3G Electric supply NELSON STUD WELDING INC. products?

Yes — 3G Electric (S) Pte. Ltd. supplies NELSON STUD WELDING INC. products. We stock the NELSON STUD WELDING INC. catalog and supply genuine factory-original products with full manufacturer warranty and technical support.
