Site Welding Steel Fabrication

Steel is seen as one the best materials to use in the construction and manufacturing industries. This is because of its, strength, durability and the ease at which in can be shaped and moulded to a specific shape. The process of steel fabrication plays in massive role in modern society and is seen in everyday society from the cars we drive to the offices where we work. One thing that goes hand in hand with steel fabrication is welding and many companies offer these services alongside site welding. Steel fabrication would not be possible without welding and it is an in-demand skill both in the fabrication shops and on-site.

What is site welding?

Many fabrication companies rely heavily on teams specialising in site welding. Steel fabrication is often used for large and awkward projects such as the construction of structural buildings, fencing and stairs; site welders are needed in both the installation and erection process and for maintenance purposes.

Large fabrication projects cannot be fully assembled during at the fabrication shop and assembly must be carried out once the steel has been delivered to site. This is generally done using bolts and fasteners although the welding together of pieces is also often required.

Site welding is often used in the case of emergencies and companies employ teams that can easily access different areas of the UK to perform site weld. Steel fabrication emergency site welding jobs are generally repair issues when an original weld has failed; security issues, HGV, mines and civil engineering are some other areas in which site welding is needed.

On site welders are able to provide services, 24 hours a day and 7 days a week and supply vehicles which are equipped with the latest equipment for welding.

What types of welding techniques are used?

There is general no difference between fab shop and site welding, steel fabrication uses many different types of weld and the techniques are implemented in both in house and on site jobs.
The three most commonly used types of weld are:

  • MIG (Metal Inert Gas) welding
  • TIG (Tungsten Inert Gas) welding
  • MMA (Manual Metal Arc) welding

MIG welding is widely used across various types of fabrication and is popular for its ability to weld joints quickly and easily. MIG welding gives users the ability to tack weld with one hand, but is not suited to outdoor conditions which are wet and windy.

TIG welding gives the joints a more precise finish and can be applied to almost any type of steel. TIG weld tends to be used less than MIG welding on structural projects as it can be a slow process and requires the steel to be clean.

MMA welding is seen as the best for site welding, steel fabrication welders commonly use this method on structural repairs as it can be applied in adverse weather conditions. It can also be relied upon for standing the test of time and doesn’t require the steel to be in a particular condition.
