Metal fabrication is intricate and involves a broad 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.
Listed below are the three major fabrication processes that are commonly used for metals. Here you will discover details about the three main processes work, as well as their primary uses. Apart from that, there is also a short description about the finishing touches and protective coatings that can be used to fabricated metal products. This article is not advisable to be used as an instruction for DIY jobs, and this is only a guide based entirely on the practices of professional operators.
1. The Cutting Process
Despite this process sounding heavy handed, the cutting process is one of the more accurate and technical processes. The first form of the cutting technique is the sawing and shearing of metal, which can be done both manually and by the use of large machines. Furthermore, it is also possible to use heat to manually cut the metal with the use of Oxyacetylene or plasma torches. But, the most popular way of cutting metals during the fabrication is with the CNC machining. These machine can utilize 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 really useful for highly detailed projects.
Joining is the most commonly used method in the fabrication process. The joining method has a very broad category, welding and riveting or bonding with adhesives are the fabrication processes that belong to this particular method. 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. There are several items in which you can use an adhesive glue to join different components.
3. The Third Process: Bending
This process required bending the metal into the desired shape. It can be done manually, however, there are now modern machinery that replaced the traditional way of manually bending metals.
The Final Touches
The final touches to any fabricated product can be applied once all the process of cutting, joining, and bending of metals has been completed. The final touches can range from paint application for purely aesthetic reasons to something like a protective coatings such as a powder coating or sandblasting. Inquire from the manufacturer for you to be able to look for a coating that best fit your purpose and budget.
