ABSTRACT
Metal inert gas wire arc additive manufacturing (MIG-WAAM) is a type of directed energy deposition (DED) technology that is used to create complex and intricate metal components by melting and depositing metal in a layered fashion. The MIG-WAAM process involves a welding torch that feeds a continuous metal wire electrode into the welding pool. The welding torch and the workpiece are positioned by a robotic arm or a computer numerical control machine, which can move in multiple axes to create intricate geometries. It can produce large, complex parts quickly and efficiently, with minimal waste. It is also versatile and can work with a wide range of metals, including steel, titanium, aluminium, and nickel alloys. MIG-WAAM has applications in various industries, including aerospace, automotive, marine, etc. It can be used to create parts, such as engine components, turbine blades, and orthopaedic implants.
