Introduction of Bus Production Line-School Bus Welding Line

Any machine or device is made up of a variety of parts joined together. According to a certain technical requirements and assembly sequence, a number of parts are joined into parts or a number of parts, components and components, such a process of combining the components into a complete machine is known as the assembly.


Bus assembly is the final part of the entire auto manufacturing process, according to the required accuracy standards and technical requirements, combining tens of millions of various types of the qualified parts after test to be sub-assembly, assembly, and finished bus, and after rigorous testing procedures to confirm whether it is qualified throughout the manufacturing process.
