1. A welding system configured to weld a workpiece, the welding system comprising:
a welding device:
a positioner including a workpiece position setting mechanism having reference position information;
a control device configured to control the welding device and the positioner; and
at least one holding mechanism configured to hold the workpiece,
wherein the control device comprises a positioner position calculator for calculating a position of the holding mechanism when holding the workpiece based on the reference position information provided from the workpiece position setting mechanism and workpiece information inputted into the control device in advance,
wherein the workpiece position setting mechanism is movable along moving rails for the positioner, the moving rails being parallel to a length direction of the workpiece, and
wherein a side surface of the work piece position setting mechanism is provided with a reference surface for setting a reference position in the length direction of the workpiece by bringing one end of the workpiece into contact with the reference surface.
