Abstract
- Achieving a uniform welding seam with minimum overheating is crucial to obtain high quality joints in laser welding. The classical formula of the overlapping factor for laser pulsed welding was modified by the introduction of empirical corrections from the application of static pulses involving constant energy combinations of laser power and pulse duration. The energy re-allocation in the case of dynamic pulses was studied as a function of the laser displacement speed. Energy optimization criteria aiming the minimization of the energy per length unit or surface unit were introduced. An optimized uniform welding seam with minimum thermal affectation was obtained by means of dynamic pulses. [ABSTRACT FROM AUTHOR]
