Lot of innovations and improvements has been done in the production and fabrication of materials or metals. Science and technology has gifted us with a number of useful tools and systems. Industrial processes have become quite easy with the introduction of these equipments and technologies. Laser cutting is one of the useful technologies that make things quite easy. It is a system that uses a laser in cutting and shaping different types of materials, especially materials such as stainless steel, carbon steel, copper alloys and aluminum. This technology is quite popular in the metal fabrication industry. It is used to increasing cutting capacity and cutting speed, increase productivity, reduce production cost and improve cutting quality. Light Amplification by Stimulated Emission of Radiation or LASER technology is one of the greatest inventions. Laser is actually a device or tool that generates coherent and highly concentrated beam of light. With the help of stimulated emission process the light is produced. There are various types of lasers used for cutting. Carbon dioxide laser or CO2 laser is one of the common types of lasers that are used in the cutting of the metals. It is also used in welding. It has the ability to emit a maximum of hundred kilowatts are 10.6 and 9.6 µm and of cutting twenty to thirty, of 1 millimeter-thick material in a minute. Sheet metal fabrication is another useful technology. In this process raw piece of material is modified to produce a metal component. Different temperatures are used to process these materials. Depending on the temperature range, the process is classified as hot, warm and cold. There are various types of sheet metal fabrication processes. These processes are used to form finished products from sheet metals. Objects or materials that are used and fabricated for machinery and other instruments or equipments are among the daily used objects like computer, paper clips, nails, bolts, automotive parts and more. There are a number of factors such as desired geometry, rate of production and other physical requirements that have direct impact on the fabrication process. Metal fabrication is one of the useful techniques. It has a number of advantages. It is used by a number of industries. Every laser cutting services undergoes three basic processes that include cutting forming and finishing. Various types of products are created during the sheet metal fabrication procedure. Some of the most common objects created are enclosures, metal cabinets, ventilation shafts, tanks, exhaust systems, hoods and prototypes. Various other industries also use metal fabrication. These are food storage, food dispensing, communication, computer, automotive, electronics, medical, telecommunication aerospace, residential, pharmaceutical and construction. Some of the common types of Sheet Metal Fabrication include processes like Cold forming, Annealing (heating), Cold rolling (shaping Sheet Metal with rollers), Bending (straining), Drawing, Forging, Rolling, Extrusion and Spinning.
