Sustainable Analysis of Process Parameters During MIG Welding of 1018 Mild Steel

Introduction

One of the important elements of the manufacturing field is the welding process that is also one of the significant primary manufacturing processes that uses heat and or the pressure for obtaining the required bonding between the base materials. Processing of different materials uses various manufacturing processes to process material from the properties of raw material to the desired properties. Metal Inert Gas (MIG) Welding is an arc welding process in which melting and joining of metals have been achieved by means of an arc that strike between a filler wire electrode that is continuously fed and the metals. In order to prevent from oxidation forming; a shielding gas is externally provided as a flow of inert gas. Welding plays an important role during joining in manufacturing industries. Overall welding cost is generally reduced by reducing consumption of electrical energy. MIG welding is one of the most desired welding processes in various industries than other joining processes as it is very cheap, easy to control and simple and productivity is higher. Mild steel is one of the common forms of the steel that is frequently used in construction works and in industries because of its important properties which are mostly suitable for different applications and it is also cheaper. Mild steel has also excellent weldability. The main objective of the present study is to optimize welding parameters for developing a suitable model of welding parameters that will optimize the consumption of electrical energy which is beneficial for industries to reduce overall cost of the welding process without sacrificing welded joint strength. This will lead to sustainable manufacturing. The present work also focuses to determine main influential input process parameters on energy Consumption and tensile strength by using Taguchi Method.
