Capacitor Discharge Welding (CD Welding) is an economical alternative to traditional welding processes. Its high production speeds, coupled with very low distortion welds, make CD Welding the perfect choice for welding high carbon material and dissimilar metals.
Most spot welders use two points near each other or on each side of the workpiece. The current from the capacitor is probably just absorbed by the relatively large piece of metal. The second video below from [American Tech] shows a 500F capacitor doing spot welding with little more than two wires and it seems to work.
Capacitor Discharge is by far the cleanest process with only a small witness of molten metal visible around the flange. The DA weld zone extends into the parent material to a depth of one third of the stud diameter, so plate thickness will determine where it can be used in order to avoid burn through.
The Capacitor Discharge stud welding process is ideal for thin gauge sheet where reverse marking can be minimised or completely eliminated. For CD the sheet surface should be clean and flat and the weld stud must have a precise pip and cone angle on the weld end.
The DA process requires the use of a ceramic ferrule (arc shield), to contain and shape the weld fillet, this is not reusable. Weld spatter is evident with the SC process and this can be minimised using a shrouding gas. Capacitor Discharge is by far the cleanest process with only a small witness of molten metal visible around the flange.
