Inco718 - Electron Beam Welding
Posted: Fri Jul 03, 2020 11:58 am
Hi,
please let me know how to improve: the goal is fully weld all the way to the center with minimum cross-over
test one: parameters: 130kV, 70mA, 5mm/s, under-focus 5mA - diameter 96mm
test two: parameters: 130kV, 75mA, 5mm/s, under-focus 20mA- diameter 96mm
notice the porosity near the center due to cross over
what to change?
