The Processes of Metal Fabrication

Metal fabrication is very complex and it contains an extensive range of processes. Either you want something made as a once off, or you want something mass produced, it is essential that you understand fabrication and the different processes that go into it.

In this article you will know the three main processes of fabrication that are used for metal. You will discover some details on how these processes work and also their primary uses. Aside from that, this article will also include a short explanation about protective coatings and finishing touches that can be applied to any fabricated metal products. This article is only a guide based on the practices of professional operators and is not an instruction for DIY jobs.

1. Cutting
This process is one of the more technical and accurate processes. The physical shearing and sawing of the metal is the initial variant of the cutting technique, it is normally done using large machines but it can also be achieved if done manually. Aside from it, you also use Oxyacetylene or plasma torches to cut the metal using heat. But, the most popular way of cutting metals during the fabrication is with the CNC machining. These kind of machines can use laser cutting, manual tools, or even water jets. The first thing to do when using CNC machine is to program the specific design that you like into the machine, then the metal will be shaped by one of the tools according to the shape specified by the computer design. This method is very helpful for highly delicate projects, in particular.

2. The Second Process: Joining
Joining is the most commonly used method in the fabrication process. Fabrication processes that are part of the “joining” category are welding and riveting or bonding with adhesives. Welding, is the process of joining together two pieces of metal with the heat and a filler material. Riveting process is similar to welding, it also joins two pieces of metal together, however, riveting does not require heat and only use a metal rivet. In some items, it is possible to use adhesive glue to join together different components.

3. The Third Process: Bending
The bending process involves bending the metal according to the shape you want. This can done manually, but today modern machines replaced the traditional way of manually bending the metals.

The Final Touches

After all the cutting, joining, and bending of metals are finished, the final touches can be applied already. There are wide range of final touches, from putting paint for aesthetic reasons to protective coatings like sandblasting or powder. Inquire from the manufacturer for you to be able to look for a coating that best fit your purpose and budget.
