Abstract

Capacitor discharge (CD) stud welding is a stud arc welding process in which the tip of the stud melts almost instantly when energy stored in capacitors is discharged through it. This article describes the three basic modes of the CD stud welding: initial-gap welding, initial-contact welding, and drawn-arc welding. It discusses the advantages and disadvantages and applications of the CD stud welding. The article describes the equipment used and the personnel responsibilities during CD stud welding.
