In this method a small projection (pip) at the end of the stud makes contact with the work-piece and energy from the bank of charged capacitors is discharged across the contact, melting the stud projection and creating shallow molten pool in the parent plate. At this time the stud is pushed into the work-piece under controlled spring pressure, completing the weld. Energy required for given welding operation is obtained by selection of voltage across the capacitor.
This process minimizes the depth of penetration into the parent metal surface and is used for welding smaller diameter ferrous and non-ferrous studs on light gauge material. The stud can be welded on the reverse side of coated or finished sheet with little or no marking on the finished side.
