ABSTRACT:
A robot control unit for controlling a tandem arc welding system, which has a welding torch, a robot for weaving the welding torch, a leading electrode power supply, and a trailing electrode power supply, includes a leading electrode detection section and a trailing electrode detection section for detecting quantity of welding state during weaving; a leading electrode processing section for calculating amounts of electrical change; a leading electrode correction section for calculating correction amounts for correcting displacement in horizontal and vertical directions from a weld line of a weaving center trajectory based on the amounts of electrical change; a trailing electrode processing section for calculating an amount of electrical change; and a trailing electrode correction section for calculating a correction amount for correcting displacement in a rotational direction from the weld line of the weaving center trajectory based on the amount of electrical change.
