Types of Welding Services in Industrial Fabrication
In our society, manufacturing and industry serves as the foundation. It lets us 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 look at how welding plays a significant role in industrial fabrication and also, the different types of welding services.
SMAW – this is additionally 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.
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 is called as Gas Tungsten Arc Welding and as the name suggests, it uses tungsten electrode in producing the weld. When compared to SMAW welding, the electrode isn’t consumed throughout the welding process. Instead, the welded area is being protected from atmospheric contamination by inert gas which is typically Helium gas or Argon.
GMAW – referred as Gas Metal Arc Welding, it makes use of consumable wire electrode fed through welding gun. Inert shielding gas such as argon or mixture of carbon dioxide and argon is being sprayed to the welding puddle in order 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. The flux might be sufficient on its own to protect the welding puddle from contamination or shielding gas may be used depending on the filter material and other circumstances.
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. In order to protect the welding area, the combination is totally submerged.
