Steel fabrication refers to the process of bending, cutting and shaping steel so as to create industrial and household products. Unlike welding, which strengthens or repairs items, steel fabrication involves attaching metal pieces together so as to form a predefined size and shape. Fabrication requires a lot of training and experience and that is why it is undertaken by skilled technicians. This article looks at some of the techniques involved in steel fabrication.

Laser Cutting

Laser cutting has become a popular steel fabrication technique because of its accuracy and speed with which it cuts steel. With accuracy levels of up to about 0.1 mm, laser cutting lessens the time taken at the assembly line because fewer adjustments, if any, are required. Laser beams also cut accurate holes, thereby eliminating the need of steel plates to go through the second phase of drilling after being cut.

Flame Cutting

This type of steel fabrication technique is used on plates with a thickness ranging between 20mm to 300mm. It is versatile, economical and accurate, making it one of the most widely used steel cutting methods. Flame cutting makes use of LPG and oxygen in the cutting process, which gives an excellent cut quality; though, it may occasionally require grinding so as to remove the slag.

Plasma Cutting

This technique is mostly used on plate and sheet from about 4mm to 35mm thick and approximate sheet sizes of 12m x 3m. Plasma cutting has been around for quite a while, but within the last few years, its popularity has increased because of the introduction of High Definition Plasma machines that have significantly increased the cutting process. One of the advantages of these improved machines is that they reduce the taper of a cut edge from about 5 degrees to less than 1 degree, making the plates and sheets perfect for most applications

CNC Bending

CNC Bending is an extremely versatile process used to create a large number of designs to be used in general fabrication. There are several types of bends that can be done depending on the requirements of the final product.  For instance, an inch bend is done whenever a large radius is needed on a bend. Another type of bending that is common is the Square to Round bending. To ensure that the correct bend shape is achieved, an extra piece of steel is added near the bend line known as a set-end.
