Capacitor Discharge or C.D. stud welding incorporates a power source utilizing energy stored in a bank of capacitors and solid state controls permitting quick weld fusion in two to three thousands of a second. Studs used in this process are engineered with a small projection or tip, which presents a high resistance to the stored energy and rapidly disintegrates creating an arc that melts the end of the stud and a portion of the base metal. The capacitor discharge process limits the heat generated and has a low penetration level so that studs can be welded to extremely thin and/or coated materials. Used specifically for light gauge applications. No ferrule or flux is required with this process. Hand, semi-automatic and automatic feed systems can be utilized through 5/16” diameters of carbon, stainless, aluminum and brass materials.             Please contact us for further information.
