Welding means the operation of joining metals by causing coalescence due to heat. It occurs by melting the workpiece with weld pool. The joint gets stronger if this cools down. It’s heats if the weld pool is employed with the workpiece & produces weld in this 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. When we think back before, we are able to note that welding was utilized for a long time. It’s been passed through the Bronze age and the Iron age and possesses branched all over the world.
There are three types of welding, they are ARC, MIG and TIG welding. There has been many kinds of welding which may have branched as time passed. Arc welding is performed by consumable electrode by aiming to an electric arc. Parent metal & incorporating metal has to be together if the electrode is stuck. Metal Inert Gas or MIG may be the fastest way of welding. It is like wire but combined electrode and filler material. It is possible to use because the welding process has been created super easy. TIG welding utilizes a permanent non-melting electrode made from tungsten. This type of welding process is quite flexible since the metal added separately.
These three kinds of welding uses a power supplier for maintaining electric arc between electrode & base material to melt metals at the meeting point. DC or AC currents can be used as these kind of welding. In every type of welding some semi-inert gas can be used o prevent combustion within the welding region.
A welder has to be experienced for welding works. Sometimes many problems occur as a result of lack of security precautions. Working unsafely i.e without welding glass and near combustible materials is usually a dangerous. By subtracting preventive steps, the hazards of death or dangers might be reduced. As an example, inside the Arc Welding the worker must wear helmet, hand gloves & other protective things which helps the welder to operate in safely the process is essential and it has been utilized in various industries.
