In collaboration with researchers at Ohio State University, the temperature of the arc at specific locations has been made and will be compared to the model as well. The video image of the part as it is being welded and a solid model image of the robot are displayed on a web page. In conjunction with researchers at the Colorado School of Mines, NIST has developed a model of the wire in GMAW as it is being pulled through the conduit. The model can predict the friction between the wire and the liner. Experiments were conducted using a linear actuator to smoothly pull the wire through a bend in the conduit at a specific angle.
Results show agreement with the model within a few percent.
