2. Shielded metal arc welding - Wikipedia

   en.wikipedia.org/wiki/Shielded_metal_arc_welding

   Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding [1] or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.

3. Flux-cored arc welding - Wikipedia

   en.wikipedia.org/wiki/Flux-cored_arc_welding

   Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant- voltage or, less commonly, a constant- current welding power supply .

   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.

7. Hardfacing - Wikipedia

   en.wikipedia.org/wiki/Hardfacing

   For each industrial application and wear phenomena, there is a welding electrode to provide wear resistance. Hardfacing can be deposited by various welding methods: Shielded metal arc welding; Gas metal arc welding, including both gas-shielded and open arc welding; Oxyfuel welding; Submerged arc welding; Electroslag welding
