Table 4 Overview of the parameter variations with each focusing lens.
From: Welding of thin stainless-steel sheets using a QCW green laser source
Focusing lens | Theoretical focus diameter \({d}_{0}\) (µm) | Actual output power P (W) | Welding speed v (mm/s) |
|---|---|---|---|
f50 | 4.06 | 100–300 (APC mode) | 200–500 |
f100 | 8.12 | 200–500 (ACC mode) | 400–2000 |
f200 | 16.24 | 200–500 (ACC mode) | 600–2000 |
