Additive Manufacturing AM is modernizing the manufacturing industry by enabling the layer by layer deposition process to manufacture objects in nearly any form with minimum material waste However components developed utilizing the AM process have dimensional constraints To address this issue AM produced metal materials can be coupled with various welding processes This article focuses on the foundations highlighting the distinguishing features capabilities and challenges of welding based AM processes by categorizing them into two major groups arc welding based AM like Cold Metal Transfer CMT Gas Metal Arc Welding GMAW Gas Tungsten Arc Welding GTAW Plasma Arc Welding PAW and high energy density welding based AM like Laser Beam Welding LBW and Electron Beam Welding EBW The prior study findings of welding based AM metal components on mechanical characteristics and microstructural characterization have been addressed This work will aid researchers academicians and professional welders since it gathers vital information on welding based AM processes Furthermore current research in the arena of welding based AM and its future opportunities has been discussed
