The vehicle body made of industrial aluminum profile materials has the advantages of light weight, corrosion resistance, good appearance flatness and recyclable materials, so it is favored by urban transportation companies and railway transportation departments around the world.
Industrial aluminum profile vehicle bodies have irreplaceable functions in the manufacture of high speed rail, so its development speed is very fast. At present, industrial aluminum profile vehicles with all-aluminum structure have been widely used in the manufacture of EMUs and urban rail transit vehicles, especially the steel structures of high-speed EMUs are all replaced by industrial aluminum profile vehicle bodies.
In the manufacturing process of industrial aluminum profile vehicle bodies, due to the extensive use of profile splicing in the structure, and the joints are long and regular, which is convenient for the realization of automatic operations, so various intelligent welding technologies are widely used in this industry.
