Fabrication of metallic components using welding processes is of great importance in the engineering world. Alloying element added material is a necessary to fabricate industry-ready components, especially after the invention of fabrication methods using welding processes. In the present work, raw materials including iron scraps, sponge iron, and forged steel scraps are melted in a medium frequency furnace. Casting samples are cast produced as per the ASTM standards using nickel alloyed ductile iron and inspected for porosity and other defects. Tungsten inert gas welding is exercised to check for the suitability of produced alloy for the welding process. Mechanical characterization and tensile property of as-welded components were performed. Both cases were carefully examined and found with satisfactory results. Tungsten inert gas-welded samples were noticed without any weld defects; this opens the advantage to employ welding processes for the fabrication. This will certainly enhance the feasibility of welding process for various component fabrications.

通过拉伸性能和机械特性评估镍合金球墨铸铁制造和焊接的可行性
使用焊接工艺制造金属部件在工程领域非常重要。添加合金元素的材料是制造工业级组件所必需的,尤其是在使用焊接工艺的制造方法发明之后。在目前的工作中,包括铁屑、海绵铁和锻钢屑在内的原材料在中频炉中熔化。铸件样品是按照 ASTM 标准使用镍合金球墨铸铁铸造的,并检查了孔隙率和其他缺陷。进行钨惰性气体焊接以检查生产的合金是否适合焊接工艺。进行了焊接部件的机械特性和拉伸性能。两个案例都经过仔细检查,结果都令人满意。发现钨惰性气体焊接样品没有任何焊接缺陷;这开启了采用焊接工艺进行制造的优势。这肯定会提高各种部件制造的焊接工艺的可行性。
