Exploring the Mechanical Properties of mild steel by depositing metal oxide nano particles during Arc Welding process

Conventional welding techniques are used to join the conductor metals like copper is a very tedious andcostly task as it tends to form oxides during welding which gives a poor weld strength which is not feasible.Alternative means of welding like Arc welding has established itself across a wide range of industries as a cost-effective method for welding these kinds of metals. Welding is commonly used in both automotive and aerospaceindustries. The objective of this work is to study the strength of the metal before welding and after welding by usingdifferent electrodes and depositing metal oxide nano particles during arc welding process. The material chosen forthis process is copper of 1.5 mm thickness, mild steel of 4 mm and 5 mm thickness for welding purpose. Hardnessof the welded area will be calculated by using Rockwell Hardness Test. Microstructures of the welded area weredone by using optical microscope.
