In recent years, the rapid development of laser processing technology has significantly transformed the manufacturing processes in various industries, including the construction of large steel structure buildings. Space grid structures, which are widely used in modern architectural designs due to their lightweight yet strong characteristics, are one example where laser processing technologies like laser pipe cutting machines, laser plate cutting machines, pipe bending machines, and welding robots have proven to be highly effective. This article aims to explore the application of these advanced technologies in the manufacturing of space grid structures, focusing on their capabilities and benefits.
