Complete Stud Welding

Threaded Internally Reduced Base Weld Studs

Threaded Internally Reduced Base Weld Studs (TIRB) feature a reduced-diameter weld base combined with a precision-machined internal thread. The reduced base is engineered specifically for ARC stud welding, while the internally threaded body provides a concealed fastening interface without external thread projection.

  • Reduced-Diameter Weld Base Geometry
  • UNC-2B, UNF-2B & ISO Metric Internal Threads
  • Ferrule-Controlled ARC Weld Installation
  • Customer-Specified Thread Depth & Length Options

Product Overview

Threaded Internally Reduced Base Weld Studs (TIRB) feature a reduced-diameter weld base combined with a precision-machined internal thread. The reduced base is engineered specifically for ARC stud welding, while the internally threaded body provides a concealed fastening interface without external thread projection.

Commonly used in fabricated equipment, industrial assemblies, machinery components, and structural applications, these internally threaded weld studs are manufactured to customer specifications in carbon steel and stainless steel for a wide range of fastening requirements.

Threaded Internally Reduced Base Weld Stud Features

Threaded Internally Reduced Base Weld Studs combine internal fastening capability with a weld base profile specifically configured for ARC stud welding applications.

Reduced-Diameter Fusion Interface

The weld base diameter is manufactured smaller than the stud body diameter, creating a dedicated fusion zone engineered for ARC stud welding while maintaining full body-section dimensions above the weld area.

Class-Controlled Internal Thread Forms

Available with UNC-2B, UNF-2B, and ISO metric thread specifications, these studs provide compatibility with standard industrial fastening systems and project-specific engineering requirements.

Ferrule-Matched Weld Configuration

Each stud diameter corresponds to designated ferrule designs that contain the molten weld pool, support weld profile development, and assist in maintaining installation consistency.

ARC Stud Welding System Integration

Compatible with matching chuck assemblies, grip assemblies, and foot components required to maintain alignment, plunge control, and repeatable weld performance during installation.

Customer-Defined Manufacturing Dimensions

Thread size, thread depth, overall length, body diameter, and material specifications can be manufactured to drawing requirements for application-specific assemblies and fastening systems.

Carbon Steel & Stainless Steel Construction

Available in mild steel and stainless steel materials to accommodate varying structural, environmental, and corrosion-resistance requirements across industrial applications.
