Effect of Welding Parameters on MS using SMAW - A Review

In this study, on effect of welding parameters such as welding current, welding voltage, arc gap, welding speed is to be considered on mild steel specimen which is welded by Shield Metal arc welding (SMAW. Shielded metal arc welding (SMAW) process is one of the most commonly employed material joining processes utilized in the various industrial sectors such as marine, ship-building, automotive, aerospace, construction and petrochemicals etc. The increasing pressure on manufacturing sector wants the welding process to be sustainable in nature. The SMAW process incorporates several types of inputs and output streams. The sustainability concerns associated with SMAW process are linked with the various input and output streams such as electrical energy requirement, input material consumptions, slag formation, fumes emission and hazardous working conditions associated with the human health and occupational safety. Shielded Metal Arc Welding (SMAW) or the conventional arc welding process is particularly dominant in structural joints, pressure vessels and in maintenance and repair work. This process is widely used in many industrial applications due to its versatility, simplicity and indoor and outdoor applicability. A certain level of operational skills is needed in performing the SMAW process in order to obtain a quality weldment. Further, input process parameters such as current, voltage, arc gap, welding speed, electrode orientation, etc. play a vital role in the quality of the weldment. This research especially addresses and simulate mild steel in arc welding, covering industrial applications including small scale industries.
