Friction stir processing (FSP) is a method of changing the properties of a metal through intense, localized plastic deformation. [ 2 ] : 7 [ 3 ] : 1117 This deformation is produced by forcibly inserting a non-consumable tool into the workpiece, and revolving the tool in a stirring motion as it is pushed laterally through the workpiece.
Friction stir welding and its variants – friction stir spot welding and friction stir processing – are used for the following industrial applications: [43] shipbuilding and offshore, [44] aerospace, [45] [46] automotive, [47] rolling stock for railways, [48] [49] general fabrication, [50] robotics, and computers.
Dissimilar friction stir welding (DFSW) is the application of friction stir welding (FSW), invented in The Welding Institute (TWI) in 1991, [1] to join different base metals including aluminum, copper, steel, titanium, magnesium and other materials. [2] It is based on solid state welding that means there is no melting.
Friction stir welding. Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material. Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the FSW tool.
In friction stir spot welding, individual spot welds are created by pressing a rotating tool with high force onto the top surface of two sheets that overlap each other in the lap joint. The frictional heat and the high pressure plastify the workpiece material, so that the tip of the pin plunges into the joint area between the two sheets and ...

When Drossin finally got his hands on the game, "there was a lot of music already plugged into it," he says. Drossin didn't change much -- and certainly didn't rewrite the whole soundtrack before handing it off to Sega for final processing. When I pointed out some of the similarities between Jackson songs and the Sonic soundtrack, Drossin said ...
