Common Welding Services Used 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. 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 us look on how welding plays an important role in industrial fabrication and the different kinds of welding services.

SMAW – it stands for 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.

Apart from that, the flux coating releases gas vapor and the slag forms a protected environment which act as shield to the welded area from any type 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. 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 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 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 – 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. In order to protect the welding area, the combination is totally submerged.
