Abstract
Electrically assisted flow drill screwdriving processes (EAFDS) and devices are described. The methods can augment traditional FDS and allow for softening of metals of a stack-up, which can enable FDS joining of thicker and stronger materials such as boron steel. EAFDS methods can reduce cycle time and can be used to join thicker cross-sections with reduced installation torque. Also disclosed are fixtures for attachment to existing devices that can provide for the electrical augmentation of existing FDS processes.
