Analyzing Welding and Mechanical Properties of Butt Joints for Mild Steel (MS) by Arc and TIG Welding.

Abstract

The Arc welding and the tungsten inert gas (TIG) welding method most commonly used to weld ferrous metals, nonferrous metals, and other metals since it is simple, easily implemented, and achieves consistent high-quality welds. In this study, butt joints produced between two Mild steel (MS) have been achieved by using Arc welding with E6012 electrode and TIG welding with ER4047 filler metal. In there analyzing welding and mechanical properties of Butt-welding joints with two types of test like 1. Destructive Test 2. Non-Destructive Test. Destructive weld testing, as the name suggests, involves the physical destruction of a completed weld to evaluate its strength and characteristics. In there the testing procedure is conducted to understand a specimen’s material behavior, strength, quality of the welded joint, and the skill of the welder by Tensile Strength test, Impact test, Nick break test, Face bend test, Root bend test, Side bend test and Hardness test. This type of testing involves breaking a sample fillet weld that is welded on one side only. These samples have a load applied to its unwelded side and welded side, typically in a press, tension, breaking and the load is increased until the weld fails. In this experiment Non-destructive testing (NDT) is analysis technique used by industry to evaluate the properties of a material, component, structure or system for characteristic differences or welding defects and discontinuities without causing damage to the original part.
