IDEAL LS series conductor welding machines are specially designed for the effective joining of conductors and cables as well as sector-shaped and solid conductors of aluminium and copper using the chamber welding process. This creates a homogeneous, pore- and burr-free joint.
With this procedure, the cable or conductor ends are placed in a glass, ceramic or graphite sleeve (chamber) so that the ends touch. The welding sleeve material here depends on either the cable/conductor cross-section or, as may apply, welding machine output. Once the welding process has started, both ends are melted by a flowing current and welded together under a constant feed rate.
The sleeve is shattered once welding has finished. The surface of the weld is without burring, clean, smooth and hardly any thicker.
To allow the weld to be drawn into the inlet nozzle of a downstream extruder, only minor post-treatment is required.
The chamber welding procedure is suitable for both regular conductor structures and also delicate cables.
