# Welding robot system

## Abstract

Provided is a remote-controlled welding robot system that can reduce the deviation of a welding torch from a welding portion of a workpiece. A welding robot system 10 includes: a welding robot 11; a camera 12 that captures video of an unwelded welding portion of a workpiece 5; a display device 13 that displays the captured video; an acceptance unit 15 that accepts an instruction to correct a welding position from an operator in response to the display of the video; a robot control unit 16 that controls the welding robot 11 to perform welding based on teaching data and performs control for correcting the welding position according to the accepted instruction; an accumulation unit 17 that accumulates positions of multiple points on a trajectory of the welding by the welding robot 11; and a prediction unit 18 that predicts a welding path using the accumulated positions of the multiple points. The robot control unit 16 controls the welding robot 11 such that the welding torch moves along the predicted welding path.
