Arc Characteristics in Pulse-GMA Welding with Acute Groove Angles
This paper presents the experimental results of arc characteristics in pulsed GMA welding with acute groove angles of 45 and 60 deg. Electrical signals of current and voltage were measured, while the arc behavior was observed by using a high-speed camera, and their relations were investigated and analyzed to provide data that may be used for automatic joint tracking in future research. By understanding the arc characteristics, appropriate threshold current could be determined for electrode turning in weaving-type are sensor for pulsed GMA welding in acute groove angles.
