Welding Quality Analysis Using Robotic Based System

Nowadays, competition in industrial production has come to the top with technological improvements. In this competitive environment, producers need better quality, faster and less costly production methods. So, the use of industrial robotic systems is becoming increasingly widespread for different sectors. In this experimental study, the advantages of robot welding automation compared to manual welding process were analyzed. Particularly, the difference between the two processes in the welding trajectory is constantly changed, is revealed as a result of the tests. In this study, Kuka KR6 industrial robot manipulator is used for experimental welding process. Finally, according to result of the experiment, the welded workpieces obtained from the robotic welding process and the operator manual based welded workpieces are compared. The quality difference between two processes is better observed because the frequency of the trajectory changes frequently in the weld seam in the square wave form. In order to better evaluate the results of this work, the resulting parts were subjected to a tensile test in a laboratory environment. The test results showed that robotic based welding has superior performance for joint two steel plates.
