PROBLEM TO BE SOLVED: To provide a teaching method for a welding robot, which method can easily correct the position of a welding spot, and also can prevent the deterioration of the accuracy of the teaching data. SOLUTION: In this method, the welding operation is carried out as follows. Error values between the positions of the respective welding spots obtained by carrying out the off-line teaching by use of a simulation model configured on a CAD terminal and the positions of welding guns at fixed side corresponding to the positions of the above-mentioned respective welding spots measured by a laser type three-dimensional measuring machine based on the co-ordinate systems of an actual tool in the actual welding robot which is arranged in a welding site and is operated based on off-line teaching data are calculated. Then, the off-line teaching data are corrected by adding the error values to the positions of the respective welding spots in the direction opposite to the error values respectively. Then, an actual workpiece is welded by driving the actual welding robot arranged in the welding site based on the corrected off-line teaching data. COPYRIGHT: (C)2006,JPO&NCIPI
