The capacitor discharge (CD) process is suitable for attaching smaller
diameter fasteners to thin sheet metal applications. The weld cycle is
completed in milliseconds meaning that weld can be achieved without
generating pronounced distortion or discolouration on the reverse side
of the panel.
CD stud welding is a versatile single fastening process where male and
female threaded fasteners can be end joined to a sheet metal application
instantaneously. Male threaded studs, unthreaded pins as well as
internally threaded standoffs are available in a range of materials, sizes
and lengths. Single and double earth tags are also available in a range of
sizes.
Weld nuts are available in both hexagon and square styles. Ideally suited
to applications requiring high strength they are installed using industry
proven welding technology to pre-pierced metal panels.
The major advantage of weld studs and nuts is their very low cost,
however this can often be offset against the investment required for the
installation equipment. Large volume automated production runs truly
realise the cost savings of this type of fastener.
