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. 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 – 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 holds the stick in place and an electric arc is attained by making use of either alternating or direct current. In return, this causes the electrode to melt slowly while melting the metals that has to 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 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. It is using characteristic blanket of granular fusible flux which consists of various compounds similar to lime, silica, calcium fluoride as well as manganese oxide. This combination is then submerged completely to be able to protect the welding area.
