In the present study, the Weldability and microstructure of dissimilar welds of AISI 347austenitic stainless steel to ASTM A335 low alloy steel was investigated. For this purpose, gas tungsten arc welding process and two filler metals including ERNICr-3 and ER309L were used. After welding, the microstructure of the different zones of each joint, including weld metals, heat affected zone (HAZ) 1...

In the present study, the corrosion behavior of AISI 347 austenitic stainless steel to ASTM A335 low alloy steel dissimilar joint was investigated. For this purpose, two filler metals, ER309L and ERNiCr-3, were selected to be used during the gas tungsten arc welding process. To investigate the corrosion behavior of the joints after welding, the specimens were tested in 3.5% sodium chloride solu...

The dissimilar combination of 2.25Cr-1Mo (P22) and modified 9Cr-1Mo (P91) obtained using Gas Tungsten Arc Welding (GTAW) process employing the Ni-based superalloy filler ERNiCr-3 (IN82) ERNiCrMo-3 (IN625) have been investigated for microstructure evolution mechanical properties. butt weld joint was produced single bevel groove geometry. structural integrity welded measured in respect tensile st...

A dissimilar welded joint of Inconel 718 and 304L austenitic stainless steel was prepared using a combined procedure with the gas tungsten arc welding shielded metal processes by employing Ni-based fillers: ERNiCr-3 ENiCrFe-3. The joints were investigated for metallographic testing mechanical properties, relationship established between microstructure resultant properties. Microstructural obser...

In this research the interface structure of dissimilar joint between AISI 4130 and AISI316L steels produced by GTAW process was evaluated. ERNiCr-3 was used as a filler metal for this joint. After welding the microstructure of different areas including weld metals, heat affected zones and interfaces were studied by optical microscope (OM), scanning electron microscope (SEM) and energy dispersiv...
