However, the continuous advancement in science and technology, particularly the breakthroughs in the field of laser technology, has provided us with robust support to tackle these challenges. Modern laser technology, acclaimed as the magical "sword" capable of effortlessly "cutting iron like mud," has demonstrated unparalleled efficacy in the domain of rescue and demolition. Its precise and swift cutting capabilities have significantly reduced the risk of casualties in rescue operations, shortened the critical time required for demolition tasks, and greatly enhanced the efficiency and precision of the work. The application of this technology not only highlights the immense potential of technological innovation but also offers invaluable support and assurance for our rescue efforts in emergency situations. To explore the application of laser cutting technology in rescue and demolition, this paper focuses on Q235 steel plates with thicknesses of 8mm and 15mm, conducting laser cutting experiments with a fiber laser at a long distance to investigate its suitability for rescue and demolition. The experimental results indicate that the optimal cutting effects are achieved when the distance between the laser head and the workpiece is 10m with a cutting speed of 2.00mm/s and a laser power of 10kW, and when the distance is 13m with a cutting speed of 2.25mm/s and a laser power of 13kW. Appropriately selecting the cutting speed and laser power is crucial for enhancing the surface quality of the cut on Q235 steel plates and reducing the occurrence of root slag, which is essential to meet the demands of the rescue and demolition field. fiber laser laser cutting carbon steel plate Full Text Additional Declarations No competing interests reported.
