Abstract: A vehicle body assembling system forms a pre-buck section and a main buck section set along a transfer path of a floor assembly. A main buck unit is set at opposite sides of the transfer path in the main buck section, controls an upper portion of a side assembly in a state that a lower portion of each side assembly is pre-assembled to the floor assembly the pre-buck section, and assembles the upper portion of the side assembly and vehicle body parts using a second welding robot.
