Threaded stud CFA

copper-coated steelcapacitor discharge welding

Capacitor Discharge Studs are designed to be welded to thin gauge sheet material using tip ignition according to the capacitors discharge welding process. Capacitor Discharge Studs are available in many different sizes, from a base diameter of a 2 mm stud up to 12 mm. Standard material for CD Studs are: Low Carbon Copper Flashed Steel, Stainless Steel, Aluminum Alloy, and Brass. Other grades, i.e. AISI 316 (A4), AISI 310 are available on request The stud flange is designed according to EN ISO 13918. Studs made of steel 4.8 are protected against corrosion by copper coating. (Thickness : 3 to 5 µm) The paint clearing thread causes a large part of paint to run down the stud shaft so that the metal nut can be easily positioned during final assembly.
