Welding and Fabrication

"Fabrication," particularly when connected to industry, implies the construction of structures, machines, products or other tool by stamping, cutting shaping, joining and even assembling components from raw materials - most often metals.

It is generally determined suitable to assume that a fabrication operation includes welding also, but I have chosen to isolate this out as some welding operations are now very specialist techniques and they merit their own section in this article.

Often a small business that specialises in this type of work is known as a fabrication shop, but it should be noted that in most instances the personel parts and metalworking activities will overlap with engine shop work and sheet metal engineering or sheet metal work.

What sounds a uncomplicated action such as cutting metal can mean many separate things from shearing, sawing, to cutting torches and water jet cutters and finally to laser cutting tables and plasma cutting. Depending upon the speed and accuracy of what you want, and cost and ability requirements; you will all the time need to check on the capabilities and capacities of the fabrication installation that you intend to use.

In general terms the Fabrication and welding shop is likely to cover many of the following activities:

Welding

Welding is often a major part of metal fabrication and many formed parts and assemblies will be tack welded together prior to being checked for accuracy and fit.

Welding is a fabrication formula which is predominantly about joining metals or thermoplastics by causing coalescence which is generally achieved by melting the parts, adding a filler material to form the weld pool which, when cooled, becomes a very sturdy joint (the weld). This is separate to brazing and soldering which does not induce melting of the initial components but melts a material between the components to form a bond between them.

There are lots of separate forms of vigor which can be used for welding other than the gas flame most of us recognise being also; laser, galvanic arc, electron beam, friction or ultrasound. Welding is a skilled operation and requires also some safety precautions to avoid burns, shocks, eye damage, fumes etc.

Starting in Blacksmiths shops with forge welding, shielded metal arc welding is probably the commonest form of welding used today as well as the semi and fully automated processes such as gas metal arc welding (Mig) and flux-cored arc welding and as the technology advances ever onwards so too does the welding systems such as laser beam welding and electron beam welding.

Some fabrication shops will offer specialist techniques such as Mig and Tig Welding, which are briefly outlined below:

Mig Welding

Mig welding (Metal Inert Gas) or metal arc welding was originally industrialized for welding aluminium and other non-ferrous metals. It is commonly an automated or semi-automatic process whereby an electrode joins two pieces of metal as a direct current is continuously passed through a welding gun. This is done at the same time as an inert gas is also passed through the gun which stops any air borne contaminants entering the weld area.

Mig welding allows the welding process to be much faster than other methods which makes it ideal for welding softer metals such as aluminium.

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

As it is very versatile, Mig welding can be used with a wide range of metals and alloys.

Tig Welding

Tungsten inert gas welding or Tig welding, for short, is an arc welding process that uses a tungsten electrode to yield the weld.

Similar to Mig welding in that the weld area is also protected from atmospheric contamination via an inert gas (usually Helium or Argon or a combination), and a filler metal is often used, although obvious welds, called autogenous welds, do not wish this. The constant-current produces vigor which in turn, is conducted over the arc through a mixture of ionized gas and metal vapours which is known as plasma.

Tig Welding is often used to weld non-ferrous metals such as magnesium, copper alloys and aluminium and thin sections of stainless steel and as the technique gives the experienced welder greater operate over the weld it has some advantages over Mig welding in that it can yield even higher ability and stronger welds.

The filler rod is commonly made from the same material as the base metal and is used for reinforcing joints and welding heavy metals.

Several joint types are used in Tig welding inclusive of butt joints (which do not all the time wish the filler rod assistance), lap joints, angle joints and t-joints.

It is however, more complex than Mig welding and harder to learn and is much slower that most of the other techniques.

Finally it is worthwhile checking to see if the fabrication shop offers other services which could be helpful to you - in today's fast paced environment it is worth looking if your chosen supplier offers a "One-Stop" shop which could benefit you - many will now offer other services such as:

Design and prototyping
Powder coating
Assembly
Testing and final inspection
Packing and Distribution
