24 May Metal Fabrication – A Piece of History That Never Stops
Fabrication is when one thing is manipulated to become something else. Unfortunately, the most common usage of the word might have something to do with the how the truth is so often “fabricated” into something else. However, the most useful type of fabrication has been and most likely always will be metal fabrication.
It is thought that metal was discovered before people even been to write, and that it was first used to make rudimentary tools and weapons – such as arrowheads and spears. Since then, fabrication has come a long way to include metal bending, metal forming, welding, laser cutting, and much more – expanding its utility far beyond the realm of weapons and basic tools.
Metal Fabrication through History
As most high school students know – metal was first used for basic tools. You may picture a primitive arrowhead or a spear, fastened with rawhide with feathers attached- and as far as history can tell us, you wouldn’t be too wrong. These ancient examples of metal fabrication were found in caves, and for the most part every metal fabrication found was created to be used. There was no primitive plasma cutting and metal fabrication done for decorative purposes – only for survival. As far as we can tell, these were the earliest cousins of the modern, technologically savvy, metal fabrications we see today.
The Importance of Fabrication Services
Hundreds of thousands of years ago fabricated metal parts helped ancient humans survive. Today, things aren’t much different. Stainless steel, iron, aluminum, copper, and more are all used to provide us with the products we need every day, from automobile parts to metal fabrications for use by the military, and everything in between. Metal fabrication can include:
Types of Fabrication
Metal fabrication is done for a wide range of industries and applications. Metal fabricated parts include everything from car parts, aircraft components, boat propellers, holding tanks, shark cages, weapons, and much much more.
- Contract assembly: while not specifically “metal fabrication” contract assembly often involves fabrication of some sort. Contract assembly pertains to one customer contracting fabrication, machining, or assembly work to an experience provider who has all the necessary machinery. The contract assembly company usually organizes delivery as well.
- Metal bending and forming: hydraulic press brakes are the most common type of machine used to performing metal forming – a long shot from what primitive man would have used. Metal bending is done with shaped dies and mandrels to bend tubular sections without kinking them while rolling machines are used to form plate steel into a round section.
- Plasma Cutting: Plasma cutting is one metal fabricating process that ancient homo sapiens surely would have loved. Plasma cutting uses a plasma torch to cut varying thicknesses of metal – usually steel – with extreme accuracy. Through a combination of pressurized inert gas and electricity, metal fabricators create a high powered stream of pressure capable of melting metal and simultaneously blowing it away before it can dry into the cut
- Welding is a time honored technique of joining two metals. Slightly different than plasma cutting, welding can use a variety of energy sources – including heat, electricity, friction, and even ultrasound.
