1. An offline teaching method for performing, on a welding robot, offline teaching of a weld line including a segment, the offline teaching method comprising the steps of:

  • obtaining, by a computer, a position of a current step of a torch of the welding robot and a position of a next or a previous step;

    setting, by the computer, either a previous stage coordinate system ranging from the previous step to the current step or a next stage coordinate system ranging from the current step to the next step by using, if the segment of the weld line is a straight line, an XYZ coordinate system in which a direction of the weld line is a Y direction and a direction perpendicular to a surface of a base material to be welded is a Z direction;

    inputting, by an operator, an amount of travel in the set coordinate system; and

    displaying, by the computer, the torch of the welding robot such that the torch is moved along the weld line in the next stage coordinate system or the previous stage coordinate system by the amount of travel.
