Development of Hybrid Electrode for Welding Using Nano Additives from Agro-wastes

The recycle of agricultural wastes for various other needs have recently continued to attract interest of researchers. In this study, hybrid welding electrodes were developed from agricultural waste using nano additives. The nano additives were created from typical agricultural waste materials (rice husk, coconut shell, and palm kernel shell). The generated nanoparticles were incorporated into the core of a conventional Grade 8 electrode using a suitable glue. The physical and chemical properties (particle size, shape, and elemental content) of the hybrid electrodes formed were thereafter studied. Results show that the hardness of the welded junction improved as the amount of agrowastes in the electrode increased. The SEM and XRD results also displayed an improved thermal stability during welding using electrodes with introduced agrowastes. Hence the adoption of the technology of the hybrid electrodes is recommended for welding applications. Production of nano additives from easily accessible agricultural waste may result in affordable and ecologically friendly welding solutions. The discoveries are expected to aid in the development of more environmentally friendly and potentially cost-effective welding technology.
