COPPER ALLOY ELECTRODES FOR WELDING OF STUDS
Many productions of resistance welding require the welding of studs on metal sheets, these welds are carried out with the use of special copper alloy electrodes for welding of studs.
The electrodes for welding of studs consist of two components: the first component that has the mounting cone on the electrode support while the second component, with an insulated brass cylinder pressed on the electrode which in the central part has a hole corresponding to the diameter of the electrode; the outer part containing the brass cylinder is conical.
On this cone is mounted a conical cap that matches with the electrode just described.
Each type of thread of the welding stud needs its own copper alloy welding electrode called the cap holder with its cap that becomes the interchangeable component subject to wear.
