Metal fabrication is very complex and it contains an extensive range of processes. Whether you like something mass produced or as a once off, it is significant that you understand fabrication, as well as, the difficult processes that goes into it.
In this article you will know the three main processes of fabrication that are used for metal. You will not only find details about how these processes work, but also you will discover 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 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 very first variant of this technique is the physical shearing and sawing of the metal, which is usually done by big machines but it can also done manually. Furthermore, it is also possible to use heat to manually cut the metal with the use of Oxyacetylene or plasma torches. However, the most common way to cut the metals during fabrication is the use of CNC machining. These kind of machines can use laser cutting, manual tools, or even water jets. The desired design will be program into the CNC machine and the metal is shaped by one of the tools mentioned into the specified design. This method is really useful for highly detailed projects.
2. The Second Process: Joining
Joining is the most commonly used method in the fabrication process. Fabrication processes that fall under this include 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 is the process of joining two pieces of metal together by only using a metal rivet. In some items, it is possible to use adhesive glue to join together 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.
Final Touches to Fabricated Products
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.
