摘要

All tribologists know that friction can, in some circumstances, generate heat. This has been put to practical use 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 where they are to be joined. The frictional heat and high pressure plasticizes the sheets so that the tip of the tool plunges into the joint area until the tool's shoulder is in contact with the surface of the top sheet. The shoulder applies a high forging pressure which bonds the components metallurgically without melting. After a short dwell time, the tool is pulled out of the workpieces so that a spot weld can be made about every five seconds.
