Abstract
This work focuses on studying the repairing capability of defected 6.5 mm-thick
SAF 2205 duplex stainless steel (DSS) plates, welded using friction stir welding
and repaired using fusion welding processes, shielded metal arc welding (SMAW),
and gas tungsten arc welding (GTAW). A special tool made of tungsten carbide
(WC) based material, with dimensions of 12 mm pin diameter, 5.5 mm pin length,
and 20 mm shoulder diameter was used, the friction stir welding (FSW)
angles, and 2mm root face, were used without root opening. The welded joints were
inspected using both visual test (VT) and radiographic teste (RT). The mechanical
properties, corrosion resistance, micrograph, microstructure, and the balance
between ferrite and austenite phases, were investigated and analyzed for the
repaired joints. It was significantly observed that, the repaired joints were sound
with good quality, good mechanical properties, good interface between weld metal
and base metal, good balance between ferrite and austenite phases, and their
corrosion resistance is better than base metal.
