Metal fabrication is intricate and involves a broad range of processes. Whether it is something made as a once off or mass produced, it is still very important to know about fabrication and the various processes behind 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. 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 based on the practices of professional operators and is only a guide and certainly not to be used as an instruction for any DIY jobs.
1. The First Process: Cutting
This process is one of the more technical and accurate 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. Another method to cut metals during fabrication is the most with the most common way which is by using CNC machining. These machine can utilize laser cutting, manual tools, or even water jets. In CNC machine, you just have to program the design that you want and the metal is then shaped by one of the aforementioned tools into the shape identified by the computer design. This method is very useful especially for intricate projects.
The joining process is the commonly used method of fabrication. 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. Some items only required an adhesive glue to join different components.
3. The Third Process: Bending
Bending is a fabrication process which include bending the metal into the shape you like. 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
The final touches to any fabricated product can be applied once all the process of cutting, joining, and bending of metals has been completed. 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.
