The Significance of Welding in Industries
Welding means the whole process of joining metals by causing coalescence on account of heat. It occurs by melting the workpiece with weld pool. The joint gets stronger in the event it cools down. It's heats once the weld pool can be used using the workpiece & produces weld because time. In all fabrication companies welding is extremely important. Since welding has been employed in steel fabrication its uses has expanded in other industrial sectors like construction, mechanical and car manufacturing etc. If we recall previously, we are able to observe that welding had been useful for decades. It has been passed through the Bronze age and the Iron age and it has branched all over the world. 
You can find three types of welding, they are ARC, MIG and TIG welding. There have been many different kinds of welding who have branched as time passed. Arc welding is performed by consumable electrode by looking to a power arc. Parent metal & digging in metal has to be together if the electrode is stuck. Metal Inert Gas or MIG could be the simplest way of welding. It is similar to wire but combined electrode and filler material. It is easy to use since the welding process has been made very easy. TIG welding runs on the permanent non-melting electrode made of tungsten. This sort of welding process is very flexible as the metal added separately.
These 3 types of welding requires a power supplier for maintaining electric arc between electrode & base material to melt metals with the meeting point. DC or AC currents can be used as such welding. In most form of welding some semi-inert gas is utilized o prevent combustion inside the welding region.
A welder have to be properly trained for welding works. Sometimes many problems occur as a result of deficiency of health concerns. Working unsafely i.e without welding glass and near combustible materials could be a dangerous. Through preventive measures, the hazards of death or side effects might be reduced. For instance, inside the Arc Welding the worker must wear helmet, hand gloves & other protective things that helps the welder to work in safely the procedure is very essential and it has been found in various industries.
