Some facts about welding process

Welding is a sculptural process where it deals with raw items such as metal and pipes Historical monuments, construction of building, bridges, ship building, automobile, aerospace, power plants, refineries and lots of manufacturing activities needs the process of welding and it is a part of it. The manufacturing industry came to know about the importance of welding service during 20th century and new welding equipment with latest welding technology were introduced later and requirement for welding supplies increased a lot. The welding industry should be equipped with modern tools such as welding electrodes, welding torches, welding consumables and welding guns and should follow the proper welding system with appropriate welding technology.

There are different types of welding process and each one has its own merits and demerits. Arc welding is a welding technique that uses a welding power supply and creates electric arc between electrode and base materials and Forge welding is a process that joins metal by heating them to high temperature. Tig welding uses tungsten electrode to produce the weld and it is the other name for gas tungsten metal arc welding and it is used to weld thin sections of stainless steel and non ferrous metals. Mig welding is an automatic arc welding process preferred for its versatility and speed and weld aluminum and non ferrous materials. Spot welding is a process in which metal surfaces are joined by the heat obtained from resistance of current flow. Gas welding is also called as oxy-fuel welding and use gases to weld and cut metals. Stick welding or shielded metal arc welding is a manual arc welding process that uses consumable electrodes. Plasma arc welding uses plasma gas and has narrow penetration with greater energy concentration.

Plasma arc cutting is an easy process if you follow these safety precautions. Do not touch any wet surface when operating the plasma cutter equipment and don’t use plasma cutters without any proper protection. Don’t remove the ground cable, which is attached with the work object and ensure that there is proper earth since it connects with high electric circuit. In welding, electrode is used to conduct current and it is of two types such as consumable one and a non consumable one. Shielded metal arc, gas metal arc, flux cored arc and submerged arc welding comes under the category of consumable electrode methods and tig welding and plasma arc welding are non consumable electrode methods

Apart from the welding products such as mig, tig, stick and submerged arc welding products, the other products such as wire feeders, spot welders, multi process units and water coolers comes under the welding products. Welding equipment is a heat generating equipment and it is needed to be cooled by some machines. Water coolers are the instruments which prevent overheating of machines. These have the motors which create a flow of water and cool the welding equipment. Tungsten electrodes are used in tungsten arc welding process. Tungsten electrode is used to weld stainless steel and non ferrous metals and it is called as a steel electrode.
