Paper Abstract

During the process of metal welding by continuos CO2 laser, a plasma of the metallic elements is formed. In order to improve the procedure it is necesary to characteryze this plasma. We have carried out spectroscopic measurement of both temperature and electronic density. Our target was iron, and only iron lines could be identified in all our experiments. So, we were forced to use only iron lines for the plasma diagnostic. Our results show the distribution, along more of 20 mm from the target surface, of a plasma which has at its maximum a temperature of 6300 K and an electronic density of 9x1016 cm-3.
