Abstract：Entering 21st century, metal materials forming technology is revolutionizing greatly. Arc additive manufacturing
technology, due to its advantages of fast processing speed, high material utilization rate and low cost, has been tried to be
used to process various important parts. At present, gas metal arc welding (GMAW), gas tungsten arc welding (GTAW),
plasma arc welding (PAW) are mainly used in additive manufacturing (AM). At the same time, the robot, computer
simulation, subdivision algorithm and path planning optimization, process parameters, post-processing, and the internal
relationship between microstructure and performance, etc., to reduce defects, to meet the needs of different performance
indicators. In this paper, the process of arc additive manufacturing and the research status of arc additive manufacturing in
magnesium alloys are reviewed, and the future development direction of advanced arc additive manufacturing technology
and intelligence for magnesium alloys is prospected.
