Process Analysis In Laser Welding Technology
laser pulse waveform. Laser pulse waveform is an important problem in laser welding, especially for thin-plate welding. When a high-intensity laser beam is irradiated to the surface of the material, 60 ~ 98% of the laser energy is reflected and lost on the metal surface, and the reflectance changes with the surface temperature. During a laser pulse, the reflectivity of the metal varies greatly....
