Electrode position control method for tandem ARC welding, robot controller for tandem ARC welding system, and tandem ARC welding system |
摘要 |
<p>An electrode position control method according to the present invention includes a voltage detecting step of detecting voltages on a leading electrode (2a) and a trailing electrode (2b) that are brought into contact with a welding workpiece (W), a sensing step of detecting positional information of the welding workpiece from electrical changes in the voltages, a correction amount calculating step of calculating a correction amount for correcting for positional displacement of each of the leading electrode and the trailing electrode with respect to a weld line from the positional information, and a position correcting step of correcting the respective positions of the electrodes by adding or subtracting the correction amount.</p> |
