Different Welding Services Used Widely in Industrial Fabrication
The manufacturing and industry are the foundation of our society. It allows us to have high quality living and holds promising future. On the other hand, the manufacturing and industrial sectors couldn’t exist without structures, equipment as well as resources made by industrial fabrication and in return, industrial fabrication as we know couldn’t come to life without welding.
Let us look on how welding plays an important role in industrial fabrication and the different kinds of welding services.
SMAW – this is also known as Shielded Metal Arc Welding or sometimes called as stick welding. Here, the stick is referring to the electrode coated in protectant flux. Electrode holder is holding the stick in place and then, an electric arc is achieved by using either alternating or direct current. In return, this causes the electrode to melt slowly while melting the metals that has to be joined.
At the same time, the flux coating is releasing a gas vapor along with the slag creates a shielded environment that serves as protection to weld the area from any sort of 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 as Gas Metal Arc Welding, it makes use of consumable wire electrode fed through welding gun. The inert shielding gas similar to argon or combination of carbon dioxide and argon is sprayed to the welding puddle in an effort to protect it from any contamination.
MIG welding becomes a typical welding method in different industrial setting because of its relative ease and versatility. On the other hand, it’s not ideal to be used for outdoor setting as well as other locations that have 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. Flux is sometimes enough to be used to protect the welding puddle from contamination or shielding gas may be utilized which will depend on filter material and the situation.
SAW – the Submerged Arc Welding or SAW is using consumable electrode that is automatically fed. It is using characteristic blanket of granular fusible flux which consists of various compounds similar to lime, silica, calcium fluoride as well as manganese oxide. This combination is completely submerged in order to protect the welding area.
