Different Welding Services Used Widely in Industrial Fabrication
Both industry and manufacturing serve as the society’s foundation. It allows us to have high quality living and holds promising future. The manufacturing and industrial sectors on the other hand will not be able to exist without structures, equipment as well as resources that are made by industrial fabrication and as a result, industrial fabrication as we know will not come to life without welding.
Let’s check at the way welding plays a vital part in industrial fabrication and learn the different welding services used.
SMAW – this is also known as Shielded Metal Arc Welding or sometimes called as stick welding. Here, the stick is basically referring to electrode coated in protectant flux. The electrode holder holds the stick firmly in place and the electric arc is attained by making use of alternating or direct current. In return, this causes the electrode to melt slowly while melting the metals that has to be joined.
Not only that, the flux coating releases gas vapor together with slag that creates a shielded environment serving as protection to weld the area from any contamination.
GTAW – this stands for Gas Tungsten Arc Welding and uses tungsten electrode to produce weld, like what the name suggests. If you’re going to compare SMAW welding, the electrode is not consumed in the welding process. What it does instead is, it is protecting the welded area from any kind of atmospheric contamination by inert gas which is usually Helium gas or Argon.
GMAW – referred to as Gas Metal Arc Welding, it is using consumable wire electrode that’s fed through the welding gun. Inert shielding gas like Argon or perhaps, mixture of carbon dioxide and argon is sprayed over the welding puddle to be able to protect it from contamination.
Because of the relative ease and versatility that MIG welding has, it is not surprising why it is now the most used method of welding in various industrial settings. It isn’t idea on the other hand to use it in outdoor setting and other locations with high air volatility.
FCAW – Flux Cored Arc Welding or FCAW is almost the same with MIG welding but this features using special tubular wire that is filled with flux. Well, the flux might be enough by itself in protecting the welding puddle from contamination or shielding gas might be used which depends on the filter material as well as other circumstances.
SAW – it means Submerged Arc Welding and uses consumable electrode that’s automatically fed. This has characteristic blanket of granular fusible flux consisting of different compounds like lime, silica, calcium fluoride as well as manganese oxide. This combination is completely submerged in order to protect the welding area.
