The Importance of Welding in Industries

Welding means the process of joining metals by causing coalescence due to heat. It happens by melting the workpiece with weld pool. The joint gets stronger when it cools down. It’s heats when the weld pool is used with the workpiece & produces weld in that time. In all 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. If we look back in the past, we can see that welding had been used for many years. It has been passed through the Bronze age and the Iron age and it has branched around the world.

There are three kinds of welding, they are ARC, MIG and TIG welding. There have been many different kinds of welding which have branched as the years passed. Arc welding is done by consumable electrode by aiming to an electric arc. Parent metal & the addition of metal must be together when the electrode is stuck. Metal Inert Gas or MIG is the easiest way of welding. It is like wire but combined electrode and filler material. It is easy to use because the welding process has been made very easy. TIG welding uses a permanent non-melting electrode made of tungsten. This kind of welding process is very flexible because the metal added separately.

These three kinds of welding requires 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 for these kind of welding. In every type of welding some semi-inert gas is used o prevent combustion in the welding region.

A welder must be well trained for welding works. Sometimes many problems occur because of lack of safety precautions. Working unsafely i.e without welding glass and near combustible materials can be a dangerous. By taking preventive measures, the risks of death or health hazards can be reduced. For example, in the Arc Welding the worker must wear helmet, hand gloves & other protective things which helps the welder to work in safely the process is very essential and has been used in various industries.
