Özet

Aluminium is the one of the most abundant element situated in Earth's crust and using in thousands of industrial applications. In this study spectroscopic analysis for 1mm thick aluminium plates investigated and electron temperatures were calculated with using emission spectra obtained from plasma. The relation between electron temperature and shielding gas pressure, type, pulse energy, beam focus position and flow direction were observed. With using shielding gases Ar, He, N-2 at different pressures the bead widths was measured.
