The present invention relates to a method to improve a welding quality of a welding robot and, more specifically, relates to a method to improve the welding quality of a welding robot capable of preventing welding precision from being decreased by an impact, and deformation generated in a step of transferring the welding robot in order to weld a fitting cone in a container ship. Moreover, the method to improve the welding quality of a welding robot comprises: a welding pass point search working file execution step of finding a welding pass point by moving a welding robot in the same method as an actual welding using a touch sensor-equipped in a robot cart including a welding robot, and storing it as a file; a welding work execution step of welding through the welding robot while moving a welding cart to correspond to an actual welding pass point found through the pass point search working file execution step; and an abnormality of the welding quality determination step of determining a quality of a welded part to be welded to give feedback to the welding pass point search working file execution step after zero point calibration if the quality is poor, or to terminate the corresponding welding if it is in a normal range. As a welding pass point is not found and stored in a jog method, but directly found by a touch sensor before actual welding, even if precision is reduced by impact deformation during a transferring of the welding robot, relatively accurate actual welding is possible, thus reducing a working time and improving the quality of welding. |
