Capacitor Discharge
(CD) stud welding is an extremely efficient method of welding fasteners
to a wide variety of metals like mild steel, stainless steel, aluminum,
brass, copper, titanium, etc. The process utilizes a powerful bank of
capacitors to store energy at a specific voltage determined by stud size
and material. When a weld is initiated, this energy is
"discharged" through a special "ignition tip" at the
base of the stud, creating an instantaneous arc which melts both the
base of the stud and the adjoining surface on the workpiece. At the same
time, the welding gun forces the stud into the workpiece, resulting in a
permanent bond as the molten material solidifies……..all in 0.004
seconds!
Capacitor Discharge
stud welding eliminates drilling, tapping, punching, riveting, gluing,
and screwing, and is especially beneficial when working with thin gauge
materials due to the absence of reverse-side marring or discoloration.
This process is suitable for studs ranging in size from #4-40 (M3) thru
3/8-16 (M10).
Several standard
handgun models are available from stock to accommodate routine
applications, while automated production systems are available on a
custom-designed basis for high-volume applications.
Additionally, a
complete range of standard US and Metric studs is readily available from
stock in mild steel, stainless steel, and aluminum, while non-standard
stud designs and alloys are available upon request.
