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.

摘要： A tip-base metal distance control method is provided. In this method, actual welding currents are measured under a predetermined actual welding condition, and an average actual welding current under the actual welding condition is then calculated. From a reference-current storage table, an average welding current under a welding condition that corresponds to the actual welding condition is extracted, and the extracted current value is set as a reference current. The calculated average actual welding current is then compared with the reference current to obtain a comparison result. The position of a welding torch in an upward or a downward direction is then corrected based on the comparison result.

摘要： The purpose of the present invention is to have the angles of each of the drive shafts of the first articulated drive system infallibly reach the angle of the work completed position, while maintaining the rate of movement and position of the working parts of an articulated robot. If exception conditions are not satisfied, the drive shafts of first and second articulation drive systems are driven individually (S64) on the basis of interpolated points calculated in step 5 (S5). After exception conditions are satisfied (Yes side of S61), until the working parts reach the work completed position (No side of S12), the angle of each of the drive shafts of the first articulated drive system required to vary each of the drive shafts of the first articulated drive system in a linear manner with the angle at the work completed position as a target is calculated (S8), and the angle of each of the drive shafts of the second articulated drive system is calculated on the basis of the position of the working part at the interpolated point calculated in step 5 (S5) and the angle of each of the drive shafts of the first articulated drive system as calculated (S9), and the drive shafts of the first and second articulated drive systems are driven according to said calculation results (S11).
