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.
In oxy-fuel welding, a welding torch is used to weld metals. Welding metal results when two pieces are heated to a temperature that produces a shared pool of molten metal. The molten pool is generally supplied with additional metal called filler. Filler material selection depends upon the metals to be welded.
Spot welder. Resistance spot welding is a popular method used to join overlapping metal sheets of up to 3 mm thick. [52] Two electrodes are simultaneously used to clamp the metal sheets together and to pass current through the sheets.
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 ]

Electron-beam generators (electron guns) designed for welding applications can supply beams with power ranging from a few watts up to some one hundred kilowatts. "Micro-welds" of tiny components can be realized, as well as deep welds up to 300 mm or more.
