2. Spot welding - Wikipedia

   en.wikipedia.org/wiki/Spot_welding

   A portable spot welder. Spot welding (or resistance spot welding [1]) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current.

3. Electric resistance welding - Wikipedia

   en.wikipedia.org/wiki/Electric_resistance_welding

   Electric resistance welding (ERW) is a welding process in which metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. [1] Electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. [ 2 ]

   This is a list of welding processes, separated into their respective categories. The associated N reference numbers (second column) are specified in ISO 4063 (in the European Union published as EN ISO 4063 ). [ 1 ]

5. Friction stir spot welding - Wikipedia

   en.wikipedia.org/wiki/Friction_stir_spot_welding

   Friction stir spot welds have a high strength, so they are even suitable for parts that are exposed to particularly high loads. In addition to automotive and rail vehicle construction, the aerospace industry is developing the process e.g. for welding cockpit doors for helicopters. [3]
