Welding means the process of joining metals by causing coalescence because of heat. It takes place by melting the workpiece with weld pool. The joint gets stronger if it cools down. It’s heats in the event the weld pool is used with the workpiece & produces weld in that time. In all of the fabrication companies welding is very essential. Since welding has been utilized in steel fabrication its uses has expanded in other industrial sectors like construction, mechanical and car manufacturing etc. Whenever we recall previously, we are able to notice that welding was utilized for several years. Many experts have passed through the Bronze age along with the Iron age and contains branched all over the world.

There are three types of welding, they are ARC, MIG and TIG welding. There have been several types of welding which may have branched as time passed. Arc welding is completed by consumable electrode by aiming to an electric powered arc. Parent metal & adding metal have to be together when the electrode is stuck. Metal Inert Gas or MIG is the simplest way of welding. It is just like wire but combined electrode and filler material. It is easy to use because the welding process has been created super easy. TIG welding works on the permanent non-melting electrode manufactured from tungsten. This type of welding process is very flexible because the metal added separately.

These three types of welding takes 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 these kind of welding. In every kind of welding some semi-inert gas is used o prevent combustion in the welding region.

A welder should be well trained for welding works. Sometimes many problems occur due to insufficient safety precautions. Working unsafely i.e without welding glass and near combustible materials can be a dangerous. By subtracting safety measures, the hazards of death or health risks may be reduced. For instance, from the Arc Welding the staff member must wear helmet, hand gloves & other protective things which helps the welder to work in safely the procedure is important and it has been employed in various industries.
