This paper improved tracking error by making welding torch used in melting simulator that is virtually welded in virtual simulation environment with 3D printer. As a research method, the tracking error of the welding torch was recorded at least 2.5mm up to 6.3mm by using a virtual welding torch with sensors placed on the handle of the actual welding torch, but the virtual welding torch was manufactured using a 3D printer and the tracking sensor location was placed as close as possible to the base metal.
As a result of the study, the tracking error was improved from 0.3mm to 1.9mm at the minimum by comparing the result of measuring the position value from the tracking sensor of a welding torch manufactured using a 3D printer. This improved performance compared to the actual welding torch, enabling more precise welding training and more accurate representation of the virtual bead geometry. In addition, bead data, which is the basic data for training evaluation, has been recorded in more detail, enabling further subdividing the criteria for evaluation grades.
Thus, the virtual welding torch developed in this paper was able to successfully implement the actual welding environment as a virtual welding system by producing the virtual welding torch with a 3D printer. In addition, by changing various sensor locations, the error distance within 2mm was created and the accuracy was increased. Based on this, it is believed that it can be applied to more diverse virtual welding torques.
