摘要:
A welding robot in which a translational correction calculating unit corrects a target value of a leading electrode using a translational correction amount, to obtain a primary correction target value. The translational correction amount is a correction amount of a position of the leading electrode in a translational direction in a base coordinate system at a next time. A rotational correction calculating unit calculates a rotation correction amount for correcting displacement of an orientation of a torch around the leading electrode with respect to a actual weld line, and calculates a secondary correction target value resulting from correcting the primary correction target value so that the torch rotates around the leading electrode by the rotation correction amount. The displacement is caused by the correction using the translational correction amount. A manipulator is driven on the basis of the secondary correction target value.
