Metal Fabrication Processes and Equipment for Production of High Performance Products
Metal fabrication refers to the procedure of combined operations which are used to create something out of metal. The gear used to execute the operations are: metal shears, laser cutting machines, water-jets, turret punches, machining centers, press brakes, rollers, and welding machines.The most commonly used forms of metals are carbon steel, stainless steel, and aluminum. Most metal fabricators buy metal in the shapes of sheet, bar, and tubing to begin with the fabrication process.

Metal sheets are employed as a starting basis for a very large selection of metal products and may be purchased in a variety of gauges or thicknesses. When the thickness of the sheet is 3/16" or greater, it is then described "plate". Sheets are fabricated into a large number of various kinds of items such as industrial machinery, augers, conveyors, electronic enclosures, brackets, machine components, appliances, food processing equipment, just to name a few.

The first process of sheet metal fabrication is frequently to either shear, laser cut, or punch shapes into it. The equipment used to perform these steps is a metal shear, a laser, and a turret punch. Sometimes all three of the operations can be utilized while the metal is still in a flat shape. Once the basic flat shape is achieved, the metal goes to the press brake machines to make the bends. This process is called forming. Dies in a variety of shapes are employed in the press brake to create one bend or a series of bends to create the metal as specified on the prints. At this stage, some projects may be complete and will then be shipped to its end use, but often it would go to the welding tables next.

Welding is really a true art alone. It's the job of the welder to have a pile of cut and formed shapes, browse the prints, then weld the metal pieces together for the final product. There exists a plethora of welding techniques which you can use and it is very important to the welder to utilize the appropriate procedure to get a good penetrating weld that will not fail. Welders got to know how to approach the expansion and shrinking of metal since it is heated through the welding process, then cools. Many metal fabrications, especially machine parts, have narrow tolerances that must be met. Fixtures are widely used by welders to greatly help them quickly put the pieces together and hold them in the proper place while they're welding them together.

Metal tubing and barstock is another common item purchased by metal fabricators. Railings and machine frames are two very common places that tubular metal and bar can be used. Tubing is made in square, round, or rectangular shapes with a common wall thickness around 1/8", described by the as 10 or 11 gauge, or schedule 40 pipe. The reason metal tubing is often used is because it offers a whole lot strength with less metal than solid bar. Large tubing, 2-4 inches in diameter can be used to fabricate railings that are installed along highway bridges in which a very strong railing is necessary should a vehicle crash involved with it. Using tubing instead of solid bar means less weight and less expensive, both desirable to the finish user of metal fabrications. However, there are still many cases where solid bar is recommended. One case would be the shaft of a screw conveyor. There is extreme pressure applied by way of a motor to turn the auger and solid metal is essential for successful operation of the screw conveyor. Many railings are also available in bar stock or made of a variety of bar and tubing. Bar can be used on applications where the railing does not have to be super heavy duty and thinner bars are desired.Half to at least one 1 inch bar is widely used for railings in both residential and commercial purposes. Metal railings when made out of galvanized, painted, or stainless steel fabrication should be expected to last an eternity with little to no maintenance.

Strength, low to no maintenance.Long lasting. Bay area heating and cooling is the beauty of metal. That is why so many products are created with metal. Metal fabricators have the machinery and understanding of how to take base metals that are melted and manufactured by steel factories, and turn them directly into very useful products that can last a lifetime.
