Friction stir welding (FSW) method and system and the friction stir welding parts to be produced thereby .

摘要

It is located to the structural element and between that it crosses mutually and it connects the 1st and 2nd work piece mutually making use of the 1st work piece which possesses the connection territory which stipulates the bearing surface of specified form, the frictional agitation connecting part which can frictional agitation connecting (FSW) method and the system with that is disclosed. The cartridge shoulder of the FSW tool the bearing surface and pressurizes contacts, penetrates with the angle where the pin which is expanded confronts the structural element of one side of the 1st work piece from the cartridge shoulder of the FSW tool with that, the frictional agitation connecting territory is formed between the 1st and 2nd work piece. According to the form of the execution where several is desirable, it can provide the bearing surface where concave form of arch condition is formed, in that case, the cartridge shoulder of the FSW tool forms the convex form of the arch condition which engages exactly in the bearing surface. According to the form of the execution whose other things are desirable, as for the aforementioned bearing surface convex form of arch condition it is not, in that case, the cartridge shoulder of the FSW tool the bearing surface forms the concave form of the arch condition which engages exactly. Furthermore according to the form of another desirable execution, the cartridge shoulder of the bearing surface and the FSW tool respectively is plane surface.
