Metal Fabrication Processes and Its Types

March 30, 2022

Metal Fabrication is considered one of the best techniques for structural materials. As a consumer of manufactured metal products, you may not always be aware of the complexities of the processes involved. Thus, to achieve the desired changes in the material, one must carry out a range of sophisticated techniques. It includes the production methods that optimize the raw material used in these operations.

In a nutshell, this metal fabrication transforms raw materials into metal machinery or buildings. A few examples of these finished goods are metal products.

Types Of Metal Fabrication Processes

Welding

As far as metal fabrication methods go, this one is among the most popular. Welding is the process of joining two or more components using heat, pressure, and other physical processes.

You can weld with various gas metal arc welding, shielded or stick welding, and gas tungsten metal arc welding.

The Gas Metal Arc welding process delivers a shielded gas to a wire electrode. Continuous and direct power sources are great to ease the welding process during this entire procedure.

On the other hand, Stick or Shielded Metal Arc Welding uses an electrical current with a high temperature to create an arc between the metals and the electrode stack.

Finally, it is good to combine stainless steel and other heavy construction materials using Gas Tungsten Arc Welding. In this procedure, a flux-coated tubular wire is used. 

Machining

Removing unwanted materials from a product allows creates an excellent shape s a result; the term “machining” doesn’t refer to a single technique for getting rid of waste material. Extraction of these materials through milling, turning, or drilling to get the perfect result.

Perforated sheet metals are the best illustration of drilling. A high-speed turning drill is best to cut a circular hole when drilling.

A metal lathe is necessary to create this kind of metal with more precise measurements. So, it is essential when turning it. More complex and heavier materials are frequently subjected to this treatment.

Aside from the size of the raw material, milling is excellent for both significant and minor ones. Remove unwanted material from the metalwork surface using a cutter before shaping it to your specifications.

Casting is one of the world’s oldest methods of this manufacturing. It’s been around for a long time, perhaps 6,000 years. The pouring of molten material into a mold or a cast makes casting one of the simplest fabrication methods.

It is good to allow the molten raw material to cool and harden over time. Then, it can result in the final product. Even if you don’t think about it too much, the casting method has created a surprising number of commonplace items. Bolts, cast-iron nails, automobile rims, and various parts of a small timepiece are some of the more common instances of such artifacts.

Forging

To forge, one must apply a steady pounding force to this material. Even though this technique can provide a wide variety of products, a colossal hammer or die is the most commonly employed forging agent, striking the workpiece repeatedly until it takes on the desired shape.

 It is a shaped metal either at room temperature or heating it to a high temperature. Blacksmiths have utilized forging, similar to casting, to make everyday iron objects for centuries. An anvil is necessary to keep it in place while utilizing the hammer.

Extrusion

In producing long and straight pieces, the extrusion process is excellent. A mighty hydraulic press is perfect for forcing this material into a die.

There are several components in an extrusion die, such as the container and profile, the aluminum bar, and the pressing tool. For the complete process to produce a precisely-made metal product, all of these components must work properly.

One can achieve any cross-sectional shape with extrusion, whether round, rectangular, or T-shaped metal objects. Some of the most common forms of extruded metals include aluminum and copper; magnesium, steel; and lead.

Folding

Folding is a simple production process, much to casting. A brake press is all that is necessary to bend or fold a piece of metal.

For the most part, this procedure results in sheet metals. Aviation, automotive, and construction industries are just a few industries that use these materials.

Conclusion

Metal raw materials need to undergo various fabrication techniques to manufacture these construction materials with a wide range of applications. However, a continual electrical or heat application is essential for some operations. At the same time, it is essential to require physical manipulation.

There are various methods for steel structures in the Philippines, and this tutorial provides you with a better understanding of some of them.
