Abstract Scope |
Electrochemical behavior of friction stir welded (FSW), metal inert gas (MIG) welded and base AA5059H116 alloy samples is investigated. Cyclic polarization tests, Tafel tests, electrochemical impedance spectroscopy (EIS) tests, and slow strain rate tests (SSRT) are performed in 3.5 wt% NaCl solution. Fracture occurred at the interface of HAZ and TMAZ in FSWed zone specimen, and at the interface of HAZ and weld zone in MIG welded specimens. Results of SSRT tests done using different strain rates suggest that FSWed specimens are less susceptible to SCC than MIG welded specimens. |
