Project page: Simulation Based Optimization of the Time-Dependent Pulse Power for Laser Beam Welding of Aluminum Alloys in Order to Avoid Hot Cracks

This documentations is dedicated to the python package optipuls which implements a numerical model for simulation and mathematical optimization of the single spot pulsed laser beam welding of aluminium alloys. Its implementation strongly relies on the free and open-source FEniCS computing platform.

This software package allows an expert user to create numerical simulations for the single-spot pulsed laser beam welding process, formulate in a flexible way and solve the corresponding optimal control problems, and finally generate optimized laser pulse shapes. These pulse shapes can be further programmed into a laser’s power source in order to obtain fast, energy efficient, and crack-free welds.
