Types of Welding Services in Industrial Fabrication
Both industry and manufacturing serve as the society’s 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 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. 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 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 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 to as Gas Metal Arc Welding, it is using consumable wire electrode that’s fed through the welding gun. The inert shielding gas similar to argon or combination of carbon dioxide and argon is sprayed to the welding puddle in an effort to protect it from any 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. Well, the flux might be enough by itself in protecting the welding puddle from contamination or shielding gas might be used which depends on the filter material as well as 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. This combination is then submerged completely to be able to protect the welding area.
