|ABSTRACT:- different unconventional heat sources for material processing were
discussed . The heat sources such as plasma arc, electron beam and Co2 laser were employed
previously by other researchers, while " Co2laser– gas mixture" system was studied during
the present research .
Comparison between the results of present work with the others mentioned above was
made . The parameter which was adopted for comparison is the "energy consumed per unit
length" for particular thickness .The parameter is based on the equation which was suggested
by the author of this research .
Linear relationship between energy per unit length with thickness forCo2 laser alone
and "Co2laser – gasmixture " was found, while for other heat sources it was found out of the
proportionality. This comparison showed the superiority of the "Co2laser –gas mixture"
system over the other heat sources during cutting mild steel.
