Hello expertsI have two questions:-1. How to calculate penetration and upper and lower weld width in laser welding analytically (not by experiment), if you know the beam power, focal position, spot diameter at focal position and focal length.2.In experiment of laser welding i seen that if i am focusing the laser beam inside the material it is giving me less penetration rather than focusing well above the material. How can it be justified?
waiting for your valuable suggestions.
