Abstract
A three-dimensional rectangular coordinate system is set in which the direction of a weld line is the Y direction, a direction perpendicular to a surface of a material to be welded is the Z direction, and a direction perpendicular to the Y direction and the Z direction is the X direction. A coordinate system A of XYZis set as a previous stage coordinate system, which ranges from a previous step to a current step, and a coordinate system B of XYZis set as a next stage coordinate system, which ranges from the current step to a next step. The weld line is defined by these coordinate systems that use a workpiece as a reference, and an operator specifies the amount of travel of a torch in these workpiece coordinate systems. By this method, offline teaching can be accurately performed in a welding system without requiring skill in operation.
