Different Welding Services Used Widely in Industrial Fabrication
In our society, manufacturing and industry serves as the foundation. With such, we are able 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’s check at the way welding plays a vital part in industrial fabrication and learn the different welding services used.
SMAW – it stands for Shielded Metal Arc Welding or sometimes called as stick welding. The stick here isn’t literally a stick rather, 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 the process, the electrode melts slowly while also doing the same on metals that should be joined.
Not only that, the flux coating releases gas vapor together with slag that creates a shielded environment serving as protection to weld the area from any contamination.
GTAW – this is referred as Gas Tungsten Arc Welding and like the name suggests, it is using tungsten electrode to be able to produce 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 – 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 becomes a typical welding method in different industrial setting because of its relative ease and versatility. It isn’t idea on the other hand to use it in outdoor setting and other locations with 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 – the Submerged Arc Welding or SAW is using consumable electrode that is 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. In order to protect the welding area, the combination is totally submerged.
