We might not realize it in our day-to-day life, but the metal fabrication industry affects us in more ways than we can imagine. Most structures that incorporate the use of metals have to resort to fabrication to achieve the desired end result.
Fabrication of metals is defined as, “the process of bending, cutting, and assembling metal structures from various metal parts and pieces.” As you can imagine, fabrication is the job of a skilled technician.
Following are the stages involved in the fabrication process:
During this procedure, the metal is cut to size using either manual or mechanized techniques such as sawing, shearing, and chiseling. In recent times, time-saving methods such as lasers, water jets, or torches have gained popularity because they can be computer-controlled. This rather complex process often starts with a humble sheet of metal, thus this process is also often referred to as sheet metal fabrication.

- With cutting accomplished, the next step would be to bend the metal into different shapes. This is usually carried out through press brakes or via hammering. This again could be a manual or automated process. Press brakes clamp the sheet of metal using punches and die.
- Finally, the pieces are then measured again before they are all assembled via techniques such as welding, fastening, riveting, or binding. These steps more or less wrap up the basic metal fabrication process.
Metals are often also fabricated using a special process called stamping. This technique is best suited for producing large quantities of the same part. It begins with a stamp or mold is created, which is subsequently used in a stamping machine to stamp the parts out of a piece of sheet metal (in layman’s terms, it can be compared to a cookie-cutter that cuts cookies from the rolled dough).
