Many people would use site welding and fabrication as interchangeable terms. This is NOT correct! Basically, fabrication is the technique of creating a structure out of metal, while welding can be termed as a specific operation carried out during this entire process.

In other words, fabrication is the entire process, while welding is just a specific part of it. 

So simply put, welding joins together multiple pieces of metals or other materials with similar melting compositions and points using fusion.

However, fabrication is an evolutionary process that creates metal products from layouts and designs to the formation as well as finishing.

However, taking into account this fast-changing industry, many welders are able to fabricate, and many fabricators can weld as well!

The Difference

The main difference between welding and fabrication in Sydney lies in their very approach and the tools that are used in the processes.

 A comprehensive list of usual tools that are used for fabrication includes different angle grinder discs, a set of fasteners. It is interesting to take notice of the fact that most of these tools cannot be used in welding as the process asks for more specific instruments.

The list of instruments used for fabrication:

  • Abrasives
  • Adjustment Wrench
  • Benders
  • Chipping Hammers
  • Consumable electrodes
  • Cylinders with customised carts
  • Electrode holders
  • Hand files
  • Soapstone
  • TIG consumables
  • Vice and vice grips
  • Welding Clamps

The process of Welding

Welding, on the other hand, is a technique of metal forming. The process runs hand in hand with the method of sheet metal fabrication, and both of them use processes like bending and assembling, but with a specific technical difference.

Going to further details, various techniques are followed while welding. It may include the oxyacetylene, TIC (Tungsten Inert Gas) welding, and the Gas Metal Arc (GMAW) welding.

The relation between the welding and fabrication

As sheet metal fabrication, on the other hand, is an overarching technique, involving multiple processes. There are some special techniques that include:

  • Die Cutting
  • Finishing
  • Hydroforming
  • Roll forming
  • Shrinking
  • Spinning
  • Stamping
  • Stretching 

However, when it comes to counting on the similarities between the welding and fabrication (a visible chapter that comes while discussing differences - just like another side of the same coin), both the processes involve disinfecting the metal to be welded or fabricated.

In both cases, the specialists use wire brushes and organic solvents such as acetone or mild solutions of alkali or a degreaser based on citrus, but without any butoxyethanol, which scrubs off grease, oily precipitates and germs.

 Precautions to be taken

In both cases, a site welder in Sydney, as well as a fabricator, needs to take almost similar safety precautions. Because these professionals work in dangerous environments and deal with red hot metals, heavy machinery they have to be well aware of the safety measures while taking each step.

The protective gears they use include state of the art fume extraction equipment, high quality protective, flame-resistant trousers, flame resistant jackets, leather aprons or coveralls, heavy, specially designed footwear or steel toe boots that prevent slipping, thick leather gloves, helmets fitted with a visor that comes with an auto-darkening mechanism, safety goggles, hearing protection, respirators and dust masks.
