摘要：

The friction stir welding (FSW) process has been evaluated fur application on the Al 2195 cryogenic tank of the Space Transportation System. In the present study, the general corrosion, pitting and stress corrosion cracking (SCC) resistance of 2195 plates joined by FSW was investigated. Plates of Al 2219 joined by FSW were also tested for comparison purposes along with Al 2195 and Al 2219 plates joined by the variable polarity plasma are welding method. The general corrosion, SCC and pitting behavior of FSW Al 2195 and Al 2219 is presented and discussed.
