Work system and welding system

Abstract

A welding system includes a welding device including a welding head, and configured to move the welding head to a welding position and perform a welding process on a workpiece using the welding head based on an operation program, a control unit configured to execute the operation program to control the welding device, an imaging device configured to image an image of the welding position and its surroundings to output the welding position image, an image processing unit configured to input the welding position image and a reference image at a reference welding position to which the welding head is to be moved according to the operation program, calculate a correction amount between the welding position shown in the welding position image and the reference welding position, and a confidence level of the welding position, and output an image for confirming the welding position, a display unit configured to display the output image, and a program correction unit configured to correct the operation program based on the output correction amount and confidence level.
