Abstract [en]

This paper presents the results of an experimental program investigating the effects of using a pulsed laser for laser-oxygen cutting of thin section stainless steels. It was discovered that if the pulse conditions are optimised, the maximum cutting speed for a set average laser power could be increased by up to 15%. This increase in cutting speed was made possible by a change in the material removal mechanism in the cut zone. The steady state melting-oxidation-ejection process was replaced by a periodic expulsion of melt as a result of small 'explosions' caused by the spike at the beginning of each laser pulse
