Characterization of weld strength and impact toughness in the multi-pass welding of super-duplex stainless steel UNS 32750
چکیده انگلیسی


• Effect of filler metals on the weldability of super-duplex stainless steel plates.
• Contemplative explanations on the metallurgical and mechanical properties of the weldments.
• Enhanced mechanical properties of the welds at ambient room temperature.

This paper investigates the weldability, metallurgical and mechanical properties of the UNS 32750 super-duplex stainless steels joints by Gas Tungsten Arc Welding (GTAW) employing ER2553 and ERNiCrMo-4 filler metals. Impact and tensile studies envisaged that the weldments employing ER2553 exhibited superior mechanical properties compared to ERNiCrMo-4 weldments. Microstructure studies performed using optical and SEM analysis clearly exhibited the different forms of austenite including widmanstatten austenite on the weld zone employing ER2553 filler. Also the presented results clearly reported the effect of filler metals on strength and toughness during the multi-pass welding. This research article addressed the improvement of tensile and impact strength using appropriate filler wire without obtaining any deleterious phases.
