The laser beam is focused into very small light spots, achieving a high power density at the focal point. At this point, the heat input by the beam far exceeds the part reflected, conducted, or diffused by the material, and the material quickly heats up to the point of vaporization, forming pores through evaporation.

The price of laser cutting equipment is quite expensive, about 1.5 million yuan or more. With the continuous development of the storage tank industry, more and more industries and enterprises are using storage tanks, and more and more companies are entering the storage tank industry. However, due to the reduced cost of subsequent processing, it is still feasible to use this equipment in large-scale production.
