Abstract
A relative weaving motion of a welding torch relative to a weld line is given to a welding torch, by way of composing a weld main path vector for a relative movement of the weld torch along the weld line and a swing vector for a relative movement of the weld torch. And by detecting the amount of an electrical parameter of an arc of the weld torch, the amount of correction is calculated based upon the deviation between the detected amount and a predetermined reference amount. The direction of the amount of correction is determined based upon the swing vector. The relative movement of the weld torch relative to the weld line is performed by a vector composed of the weld main path vector, the swing vector, and the correction vector. In other words, the present invention features the direction of the amount of correction being definitely determined based upon the basis of the swing vector.
