Publikováno v: Optics and Spectroscopy. 115:140-146

We have conducted spectroscopic studies of the welding plasma formed in the process of welding with an ytterbium fiber laser delivering output power of up to 20 kW. The influence of shielding gases (Ar, He) on different parts of the welding plume is

The results of an in-situ plume-laser interaction measurement during welding of mild steel with a 5 kW ytterbium fiber laser are reported. A measurement of the attenuation of probe laser beam passing through the plume has allowed to estimate the plum

Autor: V N Petrovskiy, Michael Rethmeier, Igor B. Gornushkin, P.Yu. Shcheglov, Andrey Gumenyuk

Publikováno v: Laser Physics. 23:016001

This work is devoted to the investigation of the laser–matter interaction during up to 20 kW ytterbium fiber laser welding of thick mild steel plates. The plume attenuation of a probe 1.3 μm wavelength diode laser beam as well as of continuous rad
