| dc.description.abstract | Brass metal has a high strength, strong corrosion resistance, and high electrical and thermal conductivity, making it popular engineering materials in industry and electromechanical works for building water supply systems. They have a good appearance and are easily formed, but fusion welding of brass with other brass and with metals like black steel is a challenging process. The zinc evaporation during the welding process is the primary issue with these alloys in fusion welding. After the welding process, the metal is permeable after welding. Furthermore, because evaporation reduces the amount of zinc in the alloy, the material made of brass lacks its typical chemical and physical characteristics. These issues are not being sufficiently resolved when it comes to fusion welding brass metals; Investigators were instructed to use novel techniques. These issues appear to be resolved by friction welding, one of the more recent techniques created. These researches describes optimization of process parameters and give result of rotational speed, friction time and material size of Taguchi design experimental investigation by using direct drive friction welding (DDFW) methods for welding of brass with black steel rod on set up of Lathe machine with the help GRA. Finally on this research the optimization process parameter of 1200rpm rotational speed, 30sec of friction time and 15 mm diameter material size with quenching cooling system was attained. In addition of state optimizations from a Taguchi experimental process result it shows as cooling system and material size was more influenced as best performance whereas rotational speed is next to cooling system and material size influenced welding performance but from Taguchi experimental welding time is less effect or almost no effect in welding performance. | |
