2. Arc welding - Wikipedia

   en.wikipedia.org/wiki/Arc_welding

   Gas metal arc welding Man welding a metal structure in a newly constructed house in Bengaluru, India. Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals, when cool, result in a joining of the metals.

4. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   One of the most common types of arc welding is shielded metal arc welding (SMAW); [39] it is also known as manual metal arc welding (MMAW) or stick welding. Electric current is used to strike an arc between the base material and consumable electrode rod, which is made of filler material (typical steel) and is covered with a flux that protects ...

5. Plasma arc welding - Wikipedia

   en.wikipedia.org/wiki/Plasma_arc_welding

   A typical value of temperature obtained in a plasma jet torch is on the order of 28,000 °C (50,400 °F), compared to about 5,500 °C (9,930 °F) in ordinary electric welding arc. All welding arcs are (partially ionized) plasmas, but the one in plasma arc welding is a constricted arc plasma.

6. Electric arc - Wikipedia

   en.wikipedia.org/wiki/Electric_arc

   An electric arc between two nails. An electric arc (or arc discharge) is an electrical breakdown of a gas that produces a prolonged electrical discharge. The current through a normally nonconductive medium such as air produces a plasma, which may produce visible light. An arc discharge is initiated either by thermionic emission or by field ...

7. Electroslag welding - Wikipedia

   en.wikipedia.org/wiki/Electroslag_welding

   Electroslag welding (ESW) is a highly productive, single pass welding process for thick (greater than 25 mm up to about 300 mm) materials in a vertical or close to vertical position. (ESW) is similar to electrogas welding, but the main difference is the arc starts in a different location. An electric arc is initially struck by wire that is fed ...
