Fabrication is the process of producing something new from a material that is basically in the raw state. In metal fabrication this raw material is metal that is used to produce usable bars, rods, etc. metal, however, is already used material in the process and the industrialists use to fabricate as well as elongate it to enhance its service life and resistance. New infrastructures and building designs are giving rise to the trend of metal fabrication in Lake Macquarie and this emerging trend successfully feeding the needs of contractors, builders, and investors.
What Steps are followed for the Operations Metal Fabrication in Lake Macquarie
Industrialists deal with metal fabrication generally as metal forming and are distinguished from generalised metal machining. Typical machining incorporates operations such as:
Typical Operations Metal Fabrication
When we look at the processing of metal fabrication we will come to know the following manoeuvres
- Cropping and Guillotining
- Pipe Bending
All these are of equal importance without one you will not get an accomplished product from metal fabrication. Let’s put a highlight on the welding of metal!
The process of securely joining two materials together using the process of coalescence and often also a filler material is called welding. The process of welding discharges heat and energy which in turn melts the materials at the intended joint. In this way, a secure joint is formed when the materials re-solidify. Typically, metals or thermoplastics are the materials that joined.

Below different types of welding with plenty of uses are given. Read on to learn!
Shielded Metal Arc Welding
Shielded Metal Arc Welding is also known as “SMAW” or as “stick welding.” The stick in question refers to the electrode, which is coated in a protectant flux. An electrode holder holds the “stick” in place. Using either direct or alternating current an electric arc is created. This ultimately causes the slow melting of the electrode while also melting the metals to be joined. At the same time, the flux coating is released that discharges a gas vapour which, together with the slag, creates a shielded environment to protect the weld area from contamination.
It is also known as “GTAW” or “TIG welding” uses a tungsten electrode to produce the weld. Here the electrode is not consumed during the welding process as it was in SMAW welding. In fact, the weld area is protected from atmospheric impurities by an inert gas, often Argon (Ar) or Helium (He) gas. “Tungsten Inert Gas” is given the acronym “TIG” refers
Also Known as “GMAW” or “MIG welding” employs a consumable wire electrode that is fed through a welding gun. An inert shielding gas i.e., (Ar) or a mixture of Argon and Carbon Dioxide (CO2) is also sprayed over the welding puddle to protect it from contamination. Due to its versatility and relative ease MIG welding has become the most common welding method in the industry. However, it is not ideal for use outdoors or in other areas with high air volatility.
Flux-Cored Arc Welding is very similar to MIG welding however, it is characterized by having the use of a special tubular wire that is filled with flux. Depending on the filler material and other circumstances the flux may be sufficient by itself to protect the welding puddle from contamination or a shielding gas may also be used.
Simply known as“SAW,” uses a consumable electrode that is fed automatically. Consist of several compounds such as silica, lime, calcium fluoride, and manganese oxide among others, a characteristic blanket of granular fusible flux is used during this type of welding. This blanket of granular flux thus completely “submerges” the welding area thereby protecting it. Whatever type of welding you require a trustworthy welding service in Newcastle can get you up to the mark job. Never compromise the quality as it is the matter of your building foundation.
