PROBLEM TO BE SOLVED: To carry out a work positioning accurately at a time of welding and, to restrain a facility from getting into a complicated one even when the kinds of machines are changed. SOLUTION: This system comprises a transfer route 5 being installed between a work charging station 2 and a work discharge station 3 for running a transfer robot 6 freely on one hand, and a plurality of welding stations 4 with which a positioner 8 and a pair of multi joints welding robots 7 are arranged respectively. A chassis frame transferred by the transfer robot 6 from the work charging station 2 is delivered to the positioner 8 and, positioned by the positioner 8 for welding with the multi joints welding robot 7. After then, the chassis is delivered again to the transfer robot 6 so as to be transferred to the work discharge station 3.
