The effect of welding parameters on the corrosion behaviour of friction stir welded AA2024–T351

Multiscale Electrochemical Study of Welded Al Alloys Joined by Friction Stir Welding

“…Kang et al 15 carried out immersion tests of FSW AA2024 sheets in EXCO solution, and showed that pitting corrosion started and was more intense in the central region of the weld, which is conflicting with the results obtained by Bousquet et al 16 in chloride solutions. Finally, for a FSW AA2024, Jariyaboon et al 17 found that the region most susceptible to corrosion was always the weld-affected zone, however the specific region depended on the welding parameters.…”

“…17,20,26 In the present study, macroscopic corrosion tests and both global and local electrochemical techniques were used to investigate the local corrosion behavior of two different aluminum alloys (AA2024-T3 and AA7475-T761) butt-welded by FSW. In order to preserve the properties of the passive layer, thus enhancing the galvanic effects, experiments were performed using low corrosive medium (0.1 mol L −1 Na 2 SO 4 + 0.001 mol L −1 NaCl).…”

Determination corrosion rate of welded joints realised by MAG technology

“…Bežným javom je, že hoci kovy resp. zliatiny sú v tvárnenom stave odolné voči korózii, zvarenec vyrobený z týchto materiálov nie je [2][3][4][5][6]. Možné príčiny korózie zvarov je možné zhrnúť nasledovne:…”

Effect of Process Parameters on Corrosion Resistance of Aa 6101 T6 Al Alloys Welded by Friction Stir Welding

“…Jariyaboon et al [5] studied the effect of welding parameters (rotation speed and travel speed) on the corrosion behavior of friction stir welds in the high strength aluminium alloy AA2024-T351. It was found that rotation speed plays a major role in controlling the location of corrosion attack.…”
