What’s the Difference Between Welding and Metal Fabrication?

Many people get confused between welding and metal fabrication, as both the process seem quite similar. In fact, welding and metal fabrication are often overlapping processes, and both welders and metal fabricators make use of their techniques to get the final results on a project.

For instance, metal fabrication is a process that is focused on an entire metal structure or a part of that structure. It involves the designing, implementation, and installation of large structures, such as air ducts.

Welding, on the other hand, is a simple step in a larger process of designing and creating. It is a process of creation that refers to the joining together of two metals by exerting pressure. Welding can also be achieved by melting two materials together with a high-temperature torch. Then, a tougher material, known as a filler, is added neatly over the seam to make it stronger and well-fortified.

It is important to understand the differences between welding and metal fabrication so you can hire the services you require accordingly.

In this article, we will look at the two processes in more detail to understand their differences.

What is Metal Fabrication?

Metal fabrication refers to the construction of a structure using metal, and it requires various processes. These processes include design, creation, and finally, assembling the pieces to create a new structure. Metal fabrication experts usually work with raw materials, and they are experienced in every part of the process.

They begin by designing the structure, conducting the fabrication process to create the various parts of the structure, assembling the parts, and the final installation. Metal fabrication has various subtypes, which are typically categorized by the nature of the process they undergo to be completed. These subtypes include cutting, welding, stamping, punching, folding, and machining amongst others.

The majority of metal fabrication experts specialize in steel fabrication, sheet metal, and structural metals.

What is Welding?

As explained above, welding is one of the subtypes or processes undertaken in metal fabrication. In simpler words, it refers to the joining together of two pieces of materials. These materials can be glass, metal, or even thermoplastics.

There are different techniques of welding, such as TIG, which is one of the most common techniques used in most metal fabrication shops. Gas metal arc welding (GMAW) is another popular technique, alongside oxy acetylene.

The materials are joined together with the same melting points, and fusions come into play to achieve similar compositions. Many people confuse welding and fabrication because many welders are capable of fabricating metal products, while metal fabricators use the process of welding to achieve their desired results.

It is important to note that welding is a technique utilized in the metal forming process, and it is extremely crucial in metal fabrication, particularly when working with sheet metal.

Both welding and metal fabrication requires the use of similar tools and processes. Both these trades are focused on assembling and bending to achieve the final results of a finished product.
