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 cold, result in a binding of the metals.
Types of arc welding
• Shielded metal arc welding.
• MAG welding.
• MIG welding.
• Electrogas arc welding (EGW)
Arc welding is a fusion welding process used to join metals. An electric arc from an AC or DC power supply creates an intense heat of around 6500°F which melts the metal at the join between two work pieces.
An arc is generated between two conductors of electricity, cathode and anode (considering direct current, DC), when they are touched to establish the flow of current and then separated by a small distance. ... An arc is a sustained electric discharge through this ionised gas column called plasma between the two electrodes.
＊What are the advantages of arc welding?
There are a number of advantages to using arc welding compared with many other formats:
• Cost – equipment for arc welding is well-priced Benardos
Arc welding was first developed when Nikolai Benardos presented arc welding of metals using a carbon electrode at the International Exposition of Electricity, Paris in 1881, which was patented together with Stanisław Olszewski in 1887. and affordable, and the process often requires less equipment in the first place because of the lack of gas.
• Portability – these materials are very easy to transport.
• Works on dirty metal.
