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. Welding power supply - Wikipedia

   en.wikipedia.org/wiki/Welding_power_supply

   [citation needed] If a welder were to attempt to use a CV machine for a shielded metal arc welding (SMAW) task, the small fluctuations in the arc distance would cause significant fluctuations in the machine's current output. With a CC machine the welder can count on a fixed number of amps reaching the material, regardless of how short or long ...

4. Friction stud welding - Wikipedia

   en.wikipedia.org/wiki/Friction_stud_welding

   Portable equipment for friction stud welding is available for use on construction work sites, offshore, underwater and in workshops. These portable units are much lighter and smaller than the large static friction welding machines which are used, for example, in factories to weld engine components such as drive shafts .

5. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   The equipment and methods involved are similar to that of resistance welding, but instead of electric current, vibration provides energy input. When welding metals, the vibrations are introduced horizontally, and the materials are not melted; with plastics, which should have similar melting temperatures, vertically.

6. Oxy-fuel welding and cutting - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_welding_and_cutting

   The same equipment can be used for oxyacetylene blowtorches and welding torches, by exchanging the part of the torch in front of the torch valves. For a basic oxy-acetylene rig, the cutting speed in light steel section will usually be nearly twice as fast as a petrol -driven cut-off grinder.

7. Stud welding - Wikipedia

   en.wikipedia.org/wiki/Stud_welding

   Portable stud welding machines are available. Welders can also be automated, with controls for arcing and applying pressure. CNC stud welding machines can increase the speed and accuracy of manufacturing and construction work. Stud welding is versatile; typical applications include automobile bodies, electrical panels, shipbuilding and building ...
