FSW was invented at TWI in England in 1993. Our company reviewed the superior characteristics of FSW just after this and soon started working on joint research and has applied it to the manufacture of double skin body structures for railroad cars made with aluminum alloys. In this report, we describe the problems we have encountered in conjunction with application of FSW products, as well as methods for resolving these problems and, in particular, ensuring the reliability of a welded area with emphasis on our position regarding FSW tool life. Incidentally, there are a lot of double skin structures for railroad cars made with 6N01 alloy, which has superior extrudability, and therefore, we would like to state up front that this report is primarily regarding 6N01 alloy and is therefore knowledge regarding a very limited range of materials and construction.
