Abstract

The present work investigates the weldability, microstructure, and mechanical properties of 6 mm thick 2507 super duplex stainless steel were welded by multi-pass shielded metal arc welding technique (SMAW) with ER2595 electrode using different heat inputs. The produced joint was characterized and evaluated by using radiographic inspection, liquid penetrant test, scanning electron microscopy, optical microscopy, hardness and tensile test. The results obtained demonstrated that the filler electrode, heat inputs and interpass temperature are the parameters control for produce of defect-free joint. The 2507 SDSS shielded metal arc welding show an improvement in hardness and yield strength compared to the base metal. The weld zone exhibited four distinct morphologies of austenite including secondary austenite (SA), Widmanstatten austenite (WA), intra-granular austenite (IGA), and grain boundary austenite (GBA), in addition to the presence of ferrite. The ferrite content in the weld zone remained close to the balance ratio of base metal and showed no significant variation when using different welding parameters.
