Summary: Friction Friction is a Force that opposes the relative
... Friction is a Force that opposes the relative motion of two surfaces in contact. Its magnitude is determined by two factors: 1. The “roughness” of the surfaces together. This is quantified using the “coefficient of friction”, μ. a. this number is always > 0 b. this number has no units c. this number ...

Friction stir welding
Friction-stir welding (FSW) is a solid-state joining process (the metal is not melted) that uses a third body tool to join two facing surfaces. Heat is generated between the tool and material which leads to a very soft region near the FSW tool. It then mechanically intermixes the two pieces of metal at the place of the joint, then the softened metal (due to the elevated temperature) can be joined using mechanical pressure (which is applied by the tool), much like joining clay, or dough. It is primarily used on aluminium, and most often on extruded aluminium (non-heat treatable alloys), and on structures which need superior weld strength without a post weld heat treatment.It was invented and experimentally proven at The Welding Institute UK in December 1991. TWI holds patents on the process, the first being the most descriptive.
