Abstract: (1382 Views)
spectroscopic approach was used to study the effects of laser power on quality of clad layer produced with laser cladding. A CW fiber laser with a 3 KW maximum power (1080 nm) was used to produce clad with St 410 powder on St 304 substrate. The plasma plume electron temperature 
is computed from the Boltzman plot for five discrete Fe I lines at 382.782, 386.552, 393.029, 438.354 and 526.953 nm wavelength. We have found that the electron temperature decreases and dilution increases as the laser power is enhanced. Such a result could be useful to develop an online monitoring system of the dilution.
