NSRP ASE Investment: $100K
This project evaluated a new power storage and conversion concept, and led to the development of a drawn arc stud welding power source capable of being powered from common 110VAC outlets in shipyards. This technology could greatly speed up ship construction schedules by simplifying the logistics in moving stud welders among multiple work sites, without the need for a certified electrician to connect to high voltage 3-phase power. It also enhances workplace safety by reducing workers’ risk of both electric shock and arc flash. Weld quality should also be improved by the use of the drawn arc process to replace the capacitor discharge process currently used for insulation pins.
