Abstract

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.
