An Overview of Metal Fabrication


It is not known when man started working with metals, but there is no question that this discovery has held an important place in human society.  With the discovery of the seven primary metals, rudimentary metalworking emerged during the earliest civilization.  Gold, silver, mercury, copper, lead, tin, and iron are the seven primary metals.  These metals were used for making decorative pieces such as jewelry and religious relics, as well as for more functional uses such as tools, currency, and weapons  Crafting objects that are very useful for us today began a lot time ago when men using heat and their tools did metalworking.  As the years drew on, metal working become much more advanced and became more valuable to society.


The fabrication of metals and metal alloys (which is a combination of two or more metals) today are being used in almost every commercial industry.  The role of metal fabrication in the advancements of technology, transportation , agriculture, and construction is pivotal.  If you construct machines and equipment from raw materials or metals, then you are involved in metal fabrication.  Metal preparation, welding, and assembly are usually performed in fabrication businesses or fab shops.  What we call a machine shop is a business that specializes in cutting, shaping, and assembly of machine parts.  There are many companies offer both fabrication and machining services.


The construction of structural frames, miscellaneous metals for building finishes such as stair railings, and ornamental pieces such as iron driveway gates are examples of work done by fab shops and machine shops.  Metal fabrication at http://jandmweldinginc.com/welding-services/ when done for large construction project undergoes a bidding process and the contractor awards the job.  The six primary steps for metal fabrication projects are as follows: engineering, cutting and burning, forming, machining, welding, and assembly.


For the arrangement of shop drawings and the programming of equipment, metal fabrication will either outsource or have in-house manufacturing engineers and steel detailers.  When raw materials are sized in a fab shop they have the numerical control (NC) and computer numerical control (CNC) machine tools.  When cutting metal to size and forming it to its desired shape, various methods and equipment are used such as hydraulic brake presses.  The process of machining requires that strict attention be given to the engineering drawings and it involves the turning, drilling, and milling of the metal for the purpose of producing the specific parts of the project.  During this step they also use NC and CNC machine tools.  As specified in the instructions, the pieces are welded together after they are machined.  The welding process is a highly specialized skill particularly with sensitive material.  Metal fabrication ends with assembly and this includes finishing details such as painting and inspection.
