The IT CD6 stud is a bush or standoff with an internal thread, designed to be welded onto metal surfaces by capacitor discharge. Its design incorporates a calibrated ignition tip and a cold-formed flange to ensure a stable and uniform weld.
IT is the designation for an internally threaded stud according to DIN EN ISO 13918, while CD6 is the classification commonly used in capacitor discharge welding systems. Both terms refer to the same type of stud specifically prepared for CD processes.
Available materials
IT CD6 studs can be supplied in different materials according to the application and working conditions.
