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. However, the manufacturing as well as industrial sectors will not come in existence without structures, equipment as well as resources made by industrial fabrication and for that, industrial fabrication would not be available without welding.
Let’s look at how welding plays a significant role in industrial fabrication and also, the different types of welding services.
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 is making the electrode melt slowly while also melting the metals that need 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. In comparison to SMAW welding, the electrode is not consumed throughout 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. 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 – it means Submerged Arc Welding and uses consumable electrode that’s automatically fed. 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.
