Estimating the term…
A torch is moved by a manipulator in a direction separating from a base material 7 while a wire is supplied, whereby an actuator driving the robot manipulator can control a velocity of the wire for a workpiece by a unidirectional operation of separating the torch, and vibration due to reverse of torch velocity is not generated. Further, by using a dedicated separation control system, velocity follow-up performance of the actuator moving the torch can be heightened without increasing overshoot in the usual operation time, and the acceleration and deceleration time of the manipulator can be reduced.
A welding system including:
A consumable electrode type welding method, which, by means of a welding system including a wire feeding unit which supplies a welding wire to a welding torch, an actuator which holds the welding torch and moves the welding torch, a controller which has a position control system and drive-controls the actuator, and a welding power supply unit which applies weld output between a workpiece and the welding wire, moves the welding torch by the actuator in a direction separating from the workpiece, thereby to control the velocity of the welding wire for the workpiece, in that the controller includes, separately from the position control system, a dedicated separation control system for moving the actuator only in the direction where the welding torch is separated from the workpiece;
