Experimental Analysis of Effect of Different Filler Rods on Mild Steel by Shielded Metal Arc Welding

Abstract

Mild steel which is also known as plain carbon steel, because of its profound industrial applications has been used as the subject for testing the effect of different filler rods via Shielded Metal Arc Welding. The different filler rods used in the present work are Austenitic Stainless Steel, Ferritic Stainless Steel and Mild Steel. Subsequently, the different welded samples have been tested to evaluate and compare significant parameters such as Tensile Strength determined by Universal Testing Machine; Hardness determined by Vickers Hardness Tesing Machine followed by its values conversion into Brinell Hardness Number in order to comply with the standards; Microstructure and Heat Affected Zone determined by Optical Microscope. These comparisons play a crucial role in determining which welded sample is more suitable and viable when it comes to the Mechanical Engineering Field.
