Processes Of Construction Involving Metal Fabrication

By Gregory Johnson


There are many different processes that are involved in a construction of structures and some of these are assembling, cutting, and bending the metals. And one very common process used is metal fabrication. Fabricating the metals would involve processes that make use of different raw materials for constructing a machine or a structure.

The processes are carried out more often in the fab shops. People who are going to do the projects or other tasks are called the fabricators. Fab shops will be bidding for projects and if they are already awarded, the project will then be started. However, it is very important to make sure you have chosen and hired the right Richmond metal fabrication company for the service.

Just like the other types of projects, before starting to produce an object, providing a drawing or a layout of the object is very important. Through this, doing the next steps can be much easier. The drawings or layouts must be studied carefully by workers in order to ensure that the steps are understood well. They must calculate the sizes carefully for the actual item prior to the fabrication procedures. Lastly, the installation process.

Contractors, VARs, and OEMs are three very common businesses that often employ fab shops. Usually, these are businesses that are engaged in the production of loose parts, hand railings for buildings, staircases, and structural frames for heavy tools and for buildings as well. Shops can be able to undertake small or big projects. However, some of the shops may only specialize certain projects.

Assembling, cutting, and bending are three very common processes involved. And the sub processes of cutting would include sawing, shearing, and chiseling. These three cutting methods may be done either manually or mechanically. Two common devices used in cutting are torches and control cutters. Torches also are classified into two types such as the plasma and oxy fuel types.

Hammering is done in a bending process. Similar to cutting, methods are also done through manual or mechanical ways. Using the press brakes for bending, forming the metal sheets is being done through using the methods of air bending and of coining. For positioning the parts that are cut, the CNC controlled backgauges will be used together with hard stops in order to position bed lines perfectly.

For the assembling process, the final steps of a project will be involved and to accomplish it, using adhesives, welding, threaded fasteners, and riveting methods are used. Sheet metals and structural steels are common materials for the start of projects. Other important tools include fasteners, flux, and welding wire. Production procedures are either used with human labor or with automation.

Metal surfaces may consist of some undesirable materials and these need to be removed using the refinement method or simply machining. This is very necessary for attaining the shape being desired. However, the method may be specialize or limited only to some extent. Usually, fab shops are incorporating their services with machining like metal lathes, magnet based drills, or mills.

Stores have been specializing multiple areas as well in the profession. But this will be highly dependent on the needs of the customers and expertise level in a particular specialty. Some common areas are powder coating, powder metallurgy, chipping, welding, and casting.
