文摘
- •
A new linear time invariant (LTI) model for describing UAM welder dynamics is presented.
- •
Frequency response estimation and in-situ measurements provide model verification.
- •
Shear force magnitude and welder efficiency are estimated for welding Al 6061 foil.
- •
Welder shear force and average electric power draw are correlated.
- •
The effect of UAM processing conditions on welder shear force and efficiency is analyzed.
