K4344-2 - REALWELD 18-Inch Welding Fixture Set (Lap, Butt, Fillet)

Comprehensive Fixturing for Advanced Welder Training

The Lincoln Electric REALWELD® Set of three 18 in. (457 mm) weld fixtures (K4344-2) is an essential accessory package designed to expand the capabilities of the REALWELD® training system. As welding education moves towards simulation and motion-tracking technologies, the physical interface remains critical. This set provides the necessary hardware to hold metal coupons securely in place, allowing students to practice real-world joint configurations while the system tracks their performance.

This kit includes three distinct fixtures tailored for the most common welding joints: a Lap Jig, a Butt/Groove Jig, and a Fillet Jig. Each fixture measures 18 inches (457 mm) in length, significantly longer than standard 6-inch coupons. This extended length is crucial for teaching students how to maintain consistency, travel speed, and torch angle over longer distances—skills that are vital for structural and pipe welding applications. By utilizing these fixtures, instructors can set up comprehensive curriculum modules that challenge students to maintain arc stability and bead geometry over sustained periods.

Engineered specifically for the REALWELD® environment, these fixtures integrate seamlessly with the system's positioning stand. They ensure that the workpiece is held at the correct coordinates relative to the motion-tracking sensors, guaranteeing accurate feedback on parameters such as work angle, travel angle, and contact tip-to-work distance (CTWD). The robust construction of the jigs ensures they withstand the heat and spatter of repeated live arc welding, making them a durable investment for vocational schools, unions, and industrial training centers.
