چکیده مقاله
Nickel base super alloy Haynes 230 is not only used for gas turbine components but also some combustion chambers and nozzles in thrusters or airspace engines are made of this material This research investigates the microstructure and measures the weld dimension of Haynes 230 super alloy made by three different welding methods consist of PAW, LW, and EBW Parameters of each welding method like current, linear velocity, and beam power were chosen based on experience to create an acceptable appearance weld joint Then face width, penetration depth, and heat affected zone size were measured andcompared by image analyzer software The microstructure of samples was investigated by optical and electronic microscopy equipped with EDS chemical analyses Investigations have shown that LW has the maximum face to depth ratio among samples of this research Moreover, a minimum melting of carbide phase in weld zoon was observed in LW either
