Metal Fabrication Processes and Equipment for Production of High Performance Products
Metal fabrication identifies the procedure of combined operations which are used to create something out of metal. The equipment used to perform the operations are: metal shears, laser cutting machines, water-jets, turret punches, machining centers, press brakes, rollers, and welding machines.The most commonly used types of metals are carbon steel, stainless steel, and aluminum. Most metal fabricators buy metal in the shapes of sheet, bar, and tubing to begin the fabrication process.
Metal sheets are employed as a starting basis for a very large selection of metal products and can be purchased in various gauges or thicknesses. When the thickness of the sheet is 3/16" or greater, it is then referred to "plate". Sheets are fabricated into thousands of different types of items such as industrial machinery, augers, conveyors, electronic enclosures, brackets, machine components, appliances, food processing equipment, just to name a few.
The first procedure for sheet metal fabrication is often to either shear, laser cut, or punch shapes involved with it. The equipment used to perform these steps is a metal shear, a laser, and a turret punch. Sometimes all three of the operations may be used while the metal is still in a set shape. Once the basic flat shape is achieved, the metal would go to the press brake machines to help make the bends. This process is named forming. Dies in a number of shapes are used in the press brake to create one bend or a series of bends to form the metal as specified on the prints. At this stage, some projects may be complete and may 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 is 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 use the appropriate procedure in order to get an excellent penetrating weld that won't fail. Welders must know how to approach the expansion and shrinking of metal since it is heated during the welding process, then cools. Many metal fabrications, especially machine parts, have narrow tolerances that must be met. Fixtures are trusted by welders to greatly help them quickly put the pieces together and hold them in the right place while they are welding them together.
Metal tubing and barstock is another common item purchased by metal fabricators. Railings and machine frames are two quite typical places that metal tubing and bar can be used. Tubing is manufactured in square, round, or rectangular shapes with a common wall thickness of about 1/8", referred to by the as 10 or 11 gauge, or schedule 40 pipe. The reason why metal tubing is commonly used is because it offers a lot strength with less metal than solid bar. Large tubing, 2-4 inches in diameter is used to fabricate railings that are installed along highway bridges where a very strong railing is needed should a car crash into it. Using tubing as opposed to solid bar translates to less weight and lower cost, both desirable to the finish user of metal fabrications. However, there are still many cases where solid bar is preferred. CNC Cutting Porthkerry would be the shaft of a screw conveyor. There's extreme pressure applied by a motor to turn the auger and solid metal is necessary for successful operation of the screw conveyor. Many railings are also available in bar stock or made of a combination of bar and tubing. Bar is used on applications where in fact the railing does not have to be super durable and thinner bars are desired.One half to 1 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 a lifetime with little to no maintenance.
Strength, low to no maintenance.Long lasting. That's the beauty of metal. That's why so many products are created with metal. Metal fabricators have the machinery and understanding of how exactly to take base metals that are melted and manufactured by steel factories, and turn them directly into very useful products that may last a lifetime.
