Thick plate cutting with spinning laser beam

So far thick plates of mild steel cannot have been cut with conventional methods unless high power laser is used, but cutting thick plates with 2 kW laser has been developed recently. In fact 2 kW laser is becoming a very common laser power level. A cutting experiment using a spinning laser beam method, one of such methods, was conducted. As a result, the maximum cutting thickness was increased sharply, and the cutting speed and gas consumption were improved substantially, especially for stainless steel.
