Raw metals don’t simply enter a magical machine and exit as finished products. Few people understand the extensive process of metal works custom fabrication. 

5 Common Processes of Metal  Fabrication

Below are the top five most popular processes:

 Laser cutting

 One of the greatest breakthroughs in metal works custom fabrication is the invention of laser cutting. By focusing a very high-intensity light onto metal plates, CNC operators can cut extremely precise, high-quality shapes with minimal waste.


The CNC machine moves the laser over the surface of the metal plate; cutting out virtually any shape is possible. And the results are nearly flawless due to the computer controls. Moreover, laser cutting works with a variety of metals: aluminum, stainless steels, and mild steels.



 Whereas laser cutting is at the forefront of metal works custom fabrication processes, metalworking has been around since Ancient times and is still widely in use today. Quite simply, metalworking takes advantage of metal's malleability to alter its shape through force.


 Essentially, what we're talking about is stretching, compressing, and bending the metal into the final product needed. While metalworking remains one of the most popular fabrication methods, it does have its limitations. As the metal is deformed, the weaker it becomes. If these tolerances are not monitored, the metal becomes unsafe and unusable.




 This is another popular method of metal works custom fabrication. Welders connect pieces of metal at particular points by raising the temperature around the joint to melt together. In some cases, pressure is used to form the joint after heating. However, a filler metal is most commonly used to create the joint.


 Welders can fabricate simple joints or complex geometrical shapes.


 There are several welding methods and deciding which to use is determined by some factors – e.g. the type of metal, the condition of the metal, the area in which the metal will be welded, etc.


These types of welding are:


1.       Electric - arc welding

2.       Electro-mechanical - electric resistance welding

3.       Electro-chemical - atomic hydrogen welding

4.       Chemical-mechanical - pressure gas welding

5.       Chemical - mix oxygen with a combustible fuel



Grinding and Polishing

 These are usually the final steps of the metal works custom fabrication process. At this stage, components that have undergone cutting, metalworking, or welding are ground to tolerances and polished to precision. Grinding and polishing also ensure that two similar components are identical and thus interchangeable.




 Finally, some pieces undergo plating or coating processes to provide resistance to corrosion and wear. Traditionally, fabricators have painted or lubricated metals, but today there are a plethora of durable, high-strength options that can be chosen.


Here is a sample of some typical finishing methods:






Alters the surface of aluminum trough hardening and allows for protective sealants to be applied.





Nickel plating steel is a finishing process that's been around for a long time, but certain metals can enjoy the advanced benefits of ceramic plating.





Many kinds of meals can receive powder coatings, which provide the component with a protective skin that is much stronger than paint.
