  • Difficulties and solutions for laser cutting of thick steel plates

    The laser cutting machine has no problem in cutting steel sheets below 10 mm thick. However, if a thicker steel plate is to be cut, it is often required to assist a high-power laser with an output of more than 5 kW, and the cutting quality is also significantly reduced. Due to the high cost of high-power laser devices, the laser mode of the output is also not conducive to laser cutting, so the traditional laser cutting method does not have an advantage when cutting thick plates.
