Types of Welding Services in Industrial Fabrication
In our society, manufacturing and industry serves as the foundation. 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’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 referring to the 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.
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. Rather, the welded area is protected from atmospheric contamination by inert gas which is often Helium gas or Argon.
GMAW – this is also called as Gas Metal Arc Welding which utilizes consumable wire electrode that is fed through 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.
MIG welding become the most common method of welding in various industrial settings due to 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 has strong similarity with MIG welding but FCAW is using special tubular wire that is then 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 – Submerged Arc Welding or SAW uses consumable electrode that’s fed automatically. This makes use of characteristic blanket of granular fusible flux that contains varieties of compounds including lime, silica, calcium fluoride as well as manganese oxide. This combination is then submerged completely to be able to protect the welding area.
