CD (Capacitor Discharge) stud welding is a fast and efficient method for attaching metal studs to thin sheet metal. It works by rapidly discharging stored electrical energy from capacitors through a stud, creating an arc that melts the stud's base and the sheet metal part, and then forcing the stud into the molten metal for a strong weld. This welding method is commonly used in some industries like automotive, electrical and electronics (electrical panels. enclosures, control panels), cookware, elevator...etc.
