Why Metal Fabrication Had Been So Popular Till Now?

Metal fabrication is so popular nowadays that some people think it is the backbone of modern industry. Naimor metal fabrication has been around for centuries–since the Industrial Revolution, in fact. It offers a range of opportunities, from manufacturing to engineering and maintenance.

Why Metal Fabrication Is So Popular?

We will examine the reasons for metal fabrication’s enduring popularity in this article by providing information about its four key components: design, computer-aided design (CAD), manufacturing process, and finished product. We will also mention some interesting innovations in this field that have taken place over the past few decades.

From big rocks to smartphones. Steel is everywhere. That’s why it is so important for steel makers to adopt these technologies into their existing processes. The steel process control with ai makes everything much easier.

  • Design and CAD

Metal fabrication is often involved with engineering design. It has been done in a variety of ways, from hand drawings to computer-aided design (CAD). The CAD, which can be done for complex shapes, has become more and more sophisticated.

The first step is the simple drawing of what the part will look like before its cut from a solid piece of metal. The relationships between parts are also essential (see figure 1).  Thus, the bulk of the design work consists in laying out what steel members or other materials will be used and then using tools to cut them into precise shapes.

  • Manufacturing Process

The manufacturing process starts with cutting parts out of a solid block (see figure 2). Some metal fabrication companies can use a laser to cut the part. But if it’s a more complicated shape, the work usually involves two or more different machines.

It’s also possible to fabricate precision parts by welding them together (see figure 3), which is typically done in industrial settings. If the part is large, it may be cut into smaller pieces and welded together at each point of connection.

After welding or cutting, the piece must be finished so it will have the desired shapes and dimensions (e.g., round, square and rectangular) and fit into its final fitting location correctly (see figure 4). The finishing work is usually done with sanding and other techniques.

The final product may be made into one continuous piece or have separate subassemblies (see figure 5). Common subassemblies include a bar and section, tube, square pipe and plate.  Then, it’s possible to add accessories like handles, trim and door panels (see figure 6).

  • Finished Products

The finished products may be used for a large number of purposes because they can be manufactured in different ways. Typical uses include machinery parts (such as pumps), household fixtures and decorative items such as spoons and lamps. These tend to be inexpensive items that are relatively easy to fabricate. On the other hand, they may be more complex and difficult to fabricate. In such cases, they’re often made using welding or machining techniques.

Welding is one of the most common ways to make metal fabrication products. The finished product looks like it’s been welded from a solid piece of metal (see figure 7). It’s also possible to form a smaller piece into multiple pieces by welding them together (see figure 8). For example, you can make a single part out of several pieces that have been cut and welded together (see figure 9).

Some Other Methods

Machining is another method of forming parts out of sheets and plates. Such large parts are typically made using what’s called a milling machine (see figure 10). This machine has a large wheel that can be turned to follow a pattern or a freeform shape. The holes are automatically drilled as the wheel rotates, then cut by a grinding wheel.

Machining is most commonly used for larger parts that don’t have complex designs and are easy to make. For example, large sheet-metal products may be machined from flat stock or forged into shapes after being rolled into sheets (see figure 11).

Another option is welding in place of wire drawing. This allows you to form certain shapes without cutting them out of flat materials (see figure 12). For example, you can make pipes and tubing with this type of design (see figure 13).

Laser cutting and laser welding are two more options for making metal fabrication products. The process is similar to milling, except it uses a machine with a laser instead of an abrasive wheel. The equipment used in both processes is capable of cutting small, intricate shapes. It’s also possible to cut the shape freehand (see figure 14).

In addition to these methods of forming metal fabrication products, there are other ways that a product may be made into one continuous piece, including bending, stretching, shaping, and shearing (see figure 15).

These are just some of the methods used by metal fabricators to make products. There are others that have been developed recently. In fact, the industry is highly innovative, with new technologies being invented to solve problems and make fabrication faster, simpler, and easier.

The Bottom Line

Metal fabrication has been around for centuries. It offers a range of opportunities, from manufacturing to engineering and maintenance. Computer-aided design (CAD), manufacturing process and finished product are three key elements of this craft. Another one is innovations in this field. As time goes by, metal fabricators will continue to come up with new ways of fabricating metal parts that are more efficient, safer, easier and less expensive than previous methods.
