ARC WELDING ROBOT SYSTEM

The present invention provides an arc welding robot system capable of performing optimal welding in each welding even in an environment in which the impedance and inductance of a welding circuit in each welding change. An arc welding robot system is provided with: a robot control device (4); and a parameter holding device provided to either or both of the robot control device (4) and the arc welding machine (3), the arc welding robot system acquiring impedance and inductance of a welding circuit in advance for the configuration of each object to be welded and storing the acquired impedance and inductance in the parameter holding device. The robot control device (4) performs welding control on the object to be welded on the basis of the impedance and inductance stored in the parameter holding device according to the structure of the object to be welded. 本发明提供一种电弧焊接机器人系统，即使是在各焊接中焊接电路的阻抗和电感改变那样的环境，也能够在各个焊接中进行最优的焊接。电弧焊接机器人系统具备：机器人控制装置(4)；以及参数保持装置，其设置于机器人控制装置(4)和电弧焊接机(3)这双方或者它们中的任一方，电弧焊接机器人系统针对每个焊接对象物的结构，预先获取焊接电路的
