Metal fabrication is very complicated and it covers a wide 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. In addition, a brief description regarding protective coatings and finishing touches is included, in which it is applicable to fabricated metal products. This article is only a guide based on the practices of professional operators and is not an instruction for DIY jobs.
The cutting process is more the technical and accurate processes available. 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. Another method to cut metals during fabrication is the most with the most common way which is by using CNC machining. These kind of machines can use 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.
2. The Joining Process
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 joining of two pieces of metal together using only 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.
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.
A Description on the Final Touches
Once the process of cutting, joining, and bending of metals are all done, the final touches to fabricated products can be applied. This range from applying paint for aesthetic reasons to protective coatings like 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.
