A description of typical welding techniques

By heating the surfaces to their melting points and then applying pressure to fuse them together, the fabrication process of welding unites two or more metal components.
There are various different welding methods that can be utilised, and each has special qualities, benefits, and drawbacks.
We shall examine the most popular welding methods utilised in the sector in this tutorial.

One of the most fundamental and frequently used welding processes is shielded metal arc welding (SMAW).
It entails employing a flux-coated electrode to spark an arc between the electrode and the metal.
The flux creates a gas that shelters the weld from the air while the arc melts the metal.
The SMAW welding method is adaptable and may be used for a variety of metals and thicknesses. It is also appropriate for both indoor and outdoor welding.

MIG welding, commonly referred to as gas metal arc welding (GMAW), melts metal by creating an arc from wire that is fed through a gun.
This method involves specialised equipment and does not work with all types of metal or thicknesses, but it is quite effective and results in a high-quality weld.

A non-consumable tungsten electrode is used in gas tungsten arc welding (GTAW), sometimes referred to as TIG welding, to produce the arc and melt the metal.
This kind of welding is thought to be the most accurate and is appropriate for a variety of metals and thicknesses.
However, it is less effective than other welding procedures and necessitates a high level of expertise and specific equipment.

A flux-cored wire is used in the MIG welding variant known as flux-cored arc welding (FCAW). This method requires specialised equipment and isn't appropriate for all types of metal or thicknesses, but it is more effective than SMAW and can be used for indoor and outdoor welding.

In order to create the arc and melt the metal, submerged arc welding (SAW) needs drowning the metal in a bed of flux.
