Electrospark, or electrohydraulic forming, uses a rapid discharge of electrical energy either across the gap between a pair of spaced electrodes immersed in a liquid pressure transmitting medium, or through an initiating filament connected between the electrodes. Pressure ranges up to 200,000 psi. Advantages include speed, simplicity, versatility, and economy.
