Overlay of Complex Carbide Deposition with MIG welding Using Higher Enthalpy Gases

Mechanical Engineering

Metal inert gas welding with overlay of complex carbide deposition with higher enthalpy gases is a candidate process for welding of Austenite stainless still. The overlay of work piece has found its use extensive in power generation, electronic, nuclear reactor, cooling tower, high pressurized cylinder and chemical industries due to environmental concert, energy saving, high performance, cost saving and so on however efficient welding of ss316 material has posed a major challenge due to different in thermal, mechanical and chemical property to be joint under common welding condition. Few areas of part to be required the hardness is very high so we choose the tungsten carbide and chromium mixer for used the overlay on work piece using welding process but tungsten carbide and chromium carbide mixer are very costly on the overlay of whole area of work piece. Because the part costing is more increase and the part is very costly, So we decide that the maximum hardness required on surface of part we do overlay process on that portion, so the maximum required of hardness and minimum cost is to our goal. And after using this overlay process we can achieve our goals, so using of this welding on parts to achieve higher quality and is to be done our requirement low cost and high hardness is done, with our satisfaction is also be done
