Experimental Approach for Enhancing Performance in Submerged Arc Welding Process

Submerged Arc Welding (SAW) is a popular method across many industries because it consistently produces strong, high-quality welds. But getting the best possible performance from this process isn't always straightforward. That's because many different factors—like welding settings and environmental conditions—interact in complex ways. In this study, we take a predictive approach to improve SAW performance. Our goal is to make the welds not only stronger but also more resistant to corrosion and structurally sound at a microscopic level. To test this, we ran salt spray corrosion tests to simulate harsh conditions and see how well the welded joints hold up. We also used a high-tech microscope system, the Metscope Pro, to closely study the microstructure of the welds. We experimented with different welding settings—like current, voltage, travelspeed, and the type of flux used—following a planned experimental design. What we found was pretty clear: by fine-tuning these parameters, we significantly boosted the corrosion resistance and created more uniform and refined microstructures. That means stronger, longer-lasting welds. This work provides practical insights for anyone looking to adapt the SAW process for tough environments where performance really matters.
