Characterization of large scale gas metal arc welding systems
It is often the case that newly assembled robotic welding systems that use gas metal arc welding do not perform as expected. This is often due to a lack of knowledge about the intrinsic characteristics of the welding system. The objective of this project is to provide an understanding and a methodology of characterizing large-scale arc welding systems and to provide a way to improve calibration of these systems. The results from this project demonstrate that most welding work cell calibration error is due to incorrect feedback in the welding power supply's sensing system, usually caused by ...
