  2. Spot welding - Wikipedia

    en.wikipedia.org/wiki/Spot_welding

    Spot welding. 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. The process uses two shaped copper alloy electrodes to concentrate welding ...

  3. Electric resistance welding - Wikipedia

    en.wikipedia.org/wiki/Electric_resistance_welding

    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]

  4. Robot welding - Wikipedia

    en.wikipedia.org/wiki/Robot_welding

    Robot welding is the use of mechanized programmable tools (robots), which completely automate a welding process by both performing the weld and handling the part. Processes such as gas metal arc welding, while often automated, are not necessarily equivalent to robot welding, since a human operator sometimes prepares the materials to be welded.

Two wheel-shaped electrodes roll along workpieces, applying pressure and current. Aerospace industry, steel drums, tubing. Projection welding. 23.

  6. Welding - Wikipedia

    en.wikipedia.org/wiki/Welding

    For the play, see Welded (play). Overhead stick welding. Welding is a fabrication process that joins materials, usually metals or thermoplastics, primarily by using high temperature to melt the parts together and allow them to cool, causing fusion. Common alternative methods include solvent welding (of thermoplastics) using chemicals to melt ...

  7. Electron-beam welding - Wikipedia

    en.wikipedia.org/wiki/Electron-beam_welding

    Electron-beam welding (EBW) is a fusion welding process in which a beam of high-velocity electrons is applied to two materials to be joined. The workpieces melt and flow together as the kinetic energy of the electrons is transformed into heat upon impact. EBW is often performed under vacuum conditions to prevent dissipation of the electron beam.

  8. Symbols and conventions used in welding documentation

    en.wikipedia.org/wiki/Symbols_and_conventions...

    The basic welding symbol which goes on the reference line to indicate the shape of the weld such as a fillet or plug. The symbol is placed on the arrow side or other side of the line to indicate which side of the joint the weld goes. The dimensions and other numbers such as the length of the weld or number of spot welds go above and below the ...

  9. Friction stir welding - Wikipedia

    en.wikipedia.org/wiki/Friction_stir_welding

    Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material. [1][2] Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the FSW tool. While the tool is traversed along the ...
