Welding means the whole process of joining metals by causing coalescence due to heat. It occurs by melting the workpiece with weld pool. The joint gets stronger when it cools down. It's heats when the weld pool is used using the workpiece & produces weld in that time. In all of the fabrication companies welding is very essential. Since welding has been used in steel fabrication its uses has expanded in other industrial sectors like construction, mechanical and car manufacturing etc. Whenever we recall before, we can easily notice that welding had been utilized for decades. It has been undergone the Bronze age and also the Iron age possesses branched around the globe.
There are three types of welding, they're ARC, MIG and TIG welding. There have been several types of welding which have branched as time passed. Arc welding is completed by consumable electrode by planning to a power arc. Parent metal & incorporating metal must be together when the electrode is stuck. Metal Inert Gas or MIG may be the simplest way of welding. It is just like wire but combined electrode and filler material. You can easily use as the welding process has been given super easy. TIG welding utilizes a permanent non-melting electrode made of tungsten. These kinds of welding process is very flexible since the metal added separately.
These three kinds of welding takes 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 this kind of welding. In every kind of welding some semi-inert gas is employed o prevent combustion in the welding region.
A welder must be properly trained for welding works. Sometimes many problems occur as a consequence of lack of health concerns. Working unsafely i.e without welding glass and near combustible materials can be quite a dangerous. If you take preventive measures, the potential risks of death or health hazards may be reduced. As an example, in the Arc Welding the worker must wear helmet, hand gloves & other protective points that helps the welder to operate in safely to obtain the vehicle important and has been used in various industries.
