ARC WELDING EQUIPMENT DIAGRAM
Field Of StudyOverviewEquipmentAdvantagesPower SuppliesHistoryCorrosion IssuesSafety IssuesArc 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 binding of the metals. It is a type of welding that uses a welding power supply to create an electric arc between a metal stick and the base material to melt the metals at the point of contact. Arc welders can use either direct or alternating current, and consumable or non-consuSee more on enpedia · Text under CC-BY-SA licenseThe various types of arc welding are:1.

Welders can use standard domestic current.See more on theweldingmasterTo supply the electrical energy necessary for arc welding processes, a number of different power supplies can be used. The most common classification is constant current power supplies and constant voltage power supplies. In arc welding, the voltage is directly related to the length of the arc, and the current is related to the amount of heat input. Constant current power supplies are most often used for manual welding processes such as gas tungsten arc welding and shielded metal arc welding, be..See more on enpedia · Text under CC-BY-SA licenseWhile examples of forge welding go back to the Bronze Age and the Iron Age, arc welding did not come into practice until much later. In 1800 Humphry Davy discovered the short pulsed electric arcs. Independently a Russian physicist Vasily Petrov discovered the continuous electric arc in 1802 and subsequently proposed its possible practical applications, including welding. Arc welding was first developed when Nikolai Benardos presented arc welding of metals using a carbon electrode at the InteSee more on enpedia · Text under CC-BY-SA licenseSome materials, notably high-strength steels, aluminium, and titanium alloys, are susceptible to hydrogen embrittlement. If the electrodes used for welding contain traces of moisture, the water decomposes in the heat of the arc and the liberated hydrogen enters the lattice of the material, causing its brittleness. Stick electrodes for such materials, with special low-hydrogen coating, are delivered in sealed moisture-proof packaging. New electrodes can be used straight from the can, but when moi..See more on enpedia · Text under CC-BY-SA licenseWelding can be a dangerous and unhealthy practice without the proper precautions; however, with the use of new technology and proper protection the risks of injury or death associated with welding can be greatly reduced.See more on enpedia · Text under CC-BY-SA license

Electric Arc Welding: Meaning, Procedure and Equipments
The arc welding is a fusion welding process in which the heat required to fuse the metal is obtained from an electric arc between the base metal and an electrode. The electric arc is produced when two conductors are touches together and then separated by a small gap of 2 to 4 mm, such that the current continues to flow, through the air.
