Often a very small business that specialises in this type of work is known as a fabrication shop, but it ought to be noted that in most instances the individual parts and metalworking pursuits will overlap with unit shop work and page metal engineering or page metal work.

What sounds a simple activity such as cutting metal can mean many different things from shearing, sawing, to cutting torches together with water jet cutters and finally to laser cutting tables and plasma cutting. Depending upon the pace and accuracy of what you want, and cost and top quality requirements; you will always need to be sure of the capabilities and capacities in the fabrication facility that you want to use.

In standard terms the Fabrication and welding shop is likely to cover many of these activities:

• Dropping


• Burning


• Twisting


• Wheeling


• Shearing


• Collapsable


• Forming


• Pounding


• Milling


• Tapping


• Resorting


• Welding


• Soldering

Welding

Welding can be a major part of metal fabrication and many formed parts and assemblies are going to be tack welded together just before being checked for consistency and fit.

Welding can be a fabrication method which is predominantly about joining metals or thermoplastics by causing coalescence which is commonly achieved by melting the parts, adding a filler material to form the weld pool which, when cooled, becomes an exceptionally sturdy joint (the weld). This differs to brazing and soldering which fails to induce melting of the first components but melts a material between the components to form a bond between them.

There are plenty of different forms of energy which can be used for welding besides the gas flame many of us recognise being also; lazer, electric arc, electron hug you, friction or ultrasound. Welding is a skilled operation and requires also several safety precautions and avoid burns, shocks, eye damage, fumes etc.

Starting in Blacksmiths shops using forge welding, shielded metal arc welding is among the commonest form of welding used today as well as the semi and fully automated processes which include gas metal arc welding (MIG) and flux-cored arc welding even though the technology advances truly onwards so too will the welding systems including laser beam welding and electron beam welding.

Some fabrication shops will offer you specialist techniques such as MIG and TIG Welding, which are briefly outlined below:

MIG Welding

MIG welding (Metal Inert Gas) and also metal arc welding was originally developed for welding aluminium and other non-ferrous metals. It is usually an automatic or semi-automatic approach whereby an electrode joins two fecal material metal as a immediate current is continuously passed via the welding gun. This is done as well as an inert gas is usually passed through the rifle which stops any surroundings borne contaminants entering the weld area.

MIG welding allows the welding process to become much faster than other methods so that it ideal for welding softer metals including aluminium.

It produces continuous welds faster than traditional methods, and produces cleaner welds

As it's very versatile, MIG welding can be used with a multitude of metals and alloys.

TIG Welding

Tungsten inert gas welding or TIG welding, with regard to short, is an arc welding process that utilizes a tungsten electrode to produce the weld.
