Welding means the operation of joining metals by causing coalescence due to heat. It takes place by melting the workpiece with weld pool. The joint gets stronger in the event it cools down. It's heats if the weld pool is used with the workpiece & produces weld in this time. In all of the fabrication companies welding is extremely important. Since welding has been utilized in steel fabrication its uses has expanded in other industrial sectors like construction, mechanical and car manufacturing etc. If we recall previously, we could see that welding have been used for several years. It has been passed through the Bronze age along with the Iron age and contains branched around the globe.

There are three types of welding, these are ARC, MIG and TIG welding. There has been many different kinds of welding that have branched as time passed. Arc welding is performed by consumable electrode by planning to an electric arc. Parent metal & adding metal have to be together if the electrode is stuck. Metal Inert Gas or MIG could be the simplest way of welding. It is like wire but combined electrode and filler material. It is easy to use for the reason that welding process has been manufactured a breeze. TIG welding uses a permanent non-melting electrode manufactured from tungsten. This sort of welding process is quite flexible since the metal added separately.


These 3 sorts of welding uses a power supplier for maintaining electric arc between electrode & base material to melt metals on the meeting point. DC or AC currents can be used for this kind of welding. In every single form of welding some semi-inert gas is utilized o prevent combustion in the welding region.

A welder should be properly trained for welding works. Sometimes many problems occur as a result of not enough safety measures. Working unsafely i.e without welding glass and near combustible materials can be a dangerous. By taking preventive steps, the potential risks of death or side effects could be reduced. For instance, in the Arc Welding the worker must wear helmet, hand gloves & other protective things that helps the welder to function in safely the procedure is essential and it has been used in various industries.
