Abstract:
A portable three-channel (105) inert gas flow system provides an additional inert environment around titanium (Ti) alloy deposition for robotic arc welding and wire-arc  directed energy deposition applications. The device offers not only an additional inert atmosphere around the deposition but also accelerates the cooling of the deposited  metal. The device consists of a porous plate (106) and a hexagonal straightener (107),, allowing for a lower turbulent flow of inert gas at the end of the device. The first  part of the device is the porous plate (106), which creates the positive pressure build-up in the distribution chamber and ensures uniform flow distribution throughout  the chamber. The second component is the hexagonal straightener (107), which reduces turbulence in the flow of inert gas. The delivery chamber (108) after the  hexagonal straightener reduces flow irregularity. The device reduces the turbulence intensity to 0.24 with an average gas flow rate of 60 l/min.
