چکیده انگلیسی
A cutting study with a high-power ytterbium-doped fiber laser was conducted for the dismantling of nuclear facilities. Stainless steel and carbon steel plates of various thicknesses were cut at a laser power of 6-kW. Despite the use of a low output of 6-kW, the cutting was successful for both stainless steel and carbon steel plates of up to 100â¯mm in thickness. In addition, the maximum cutting speeds against the thicknesses were obtained to evaluate the cutting performance. As representative results, the maximum cutting speeds for a 60-mm thickness were 72â¯mm/min for the stainless steel plates and 35â¯mm/min for the carbon steel plates, and those for a 100-mm thickness were 7â¯mm/min for stainless steel and 5â¯mm/min for carbon steel plates. These results show an efficient cutting capability of about 16.7â¯mm by kW, whereas other groups have shown cutting capabilities of â¼10â¯mm by kW. Moreover, the maximum cutting speeds were faster for the same thicknesses than those from other groups. In addition, the kerf widths of 60-mm and 100-mm thick steels were also obtained as another important parameter determining the amount of secondary waste. The front kerf widths were â¼1.0â¯mm and the rear kerf widths were larger than the front kerf widths but as small as a few millimeters.
