Since laser welding is a non-contact process, the only motion is making a weld pattern and the motion moving the beam from cell to cell. The weld cycle time is a combination of shots and small motion on a cell. For laser welding, the back-of-the-envelope calculation for time to process 234 weld locations is estimated to be 257.4 seconds.
