Types of Welding Services in Industrial Fabrication
Both industry and manufacturing serve as the society’s foundation. 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’s look at how welding plays a significant role in industrial fabrication and also, the different types of welding services.
SMAW – this is also known as 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 the process, the electrode melts slowly while also doing the same on metals that should 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. In comparison to SMAW welding, the electrode is not 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 to as Gas Metal Arc Welding, it is using consumable wire electrode that’s fed through the 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. 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 – the Submerged Arc Welding or SAW is using consumable electrode that is automatically fed. 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. In order to protect the welding area, the combination is totally submerged.
