What Is the Metal Fabrication Process? In every household and working environment, metal plays a major role in how people operate. Metal fabrication is the process of turning raw metals into pre-made shapes for assembly use. For example, the panels that comprise the frame of an automobile are made through custom metal fabrication processes, which are usually performed at a fabrication facility and then sent to an auto assembly plant.
However, the processes involved are complex and varied. The following sections explore and answer two simple questions: What is metal fabrication, and how does it work? When people are taught how metal fabrication works , the following processes are usually part of the training program. Each process takes a degree of practice and skill to master, and the tools and machines required are usually expensive and consume sufficient working space.
However, each metal fabrication process may be used to cut, drill, fold and weld the strongest material on earth:. Additional metal fabrication processes include broaching, honing, grinding and milling. Depending on the needs of a particular application, some metal facilities even perform specially customized types of fabrication.
Forming metal pieces for assembly use is just part of the process when it comes to making metal products. Depending on the operations at hand, a given set of assembly parts might go to a factory or independent craftsperson. In most cases, a project will start with one or more of the following materials:.
The strength and contents of sectional metals are strictly defined by the American Society for Testing Materials. Flat metals are commonly used to form the side panels on ovens, refrigerators and other household appliances. Welding wire. Used as a welding aid, the wire consists of metal strands, which are typically bound together into thicker cords and sold on spools. True to its name, the wire is used to hold two pieces of metal together during a welding application.
Usually, the wire is melted into the welded piece by the heat of the application as the process takes places. Welding wire is made of various types of metal, and it is generally found in a range of thicknesses. Custom metal fabrication processes involve complex systems of tools and machinery. To learn more about the types of processes we can perform for you, visit our custom metal fabrication services page today.
Perhaps the most commonly used metal fabrication processes involve cutting, where sheets of metal are split into halves, thirds or smaller sections. In a lot of applications, the metal being cut is freshly made, and has yet to be shaped into anything in particular.
In other applications, pre-shaped metals like bars and measured panels are submitted for cutting. Cuts are performed on a range of machinery, from lasers and plasma torches to more elaborate, high-tech pieces of machinery.
One of the more complicated processes of metal fabrication involves folding, where a metal surface is manipulated to shape at a certain angle. However, folding may only be performed in facilities that are equipped with specific, high-tech equipment due to the complexity of the whole process. In many cases where a fold is needed, the joining of two metal panels at select angles would be the more practical alternative.
Along with cutting, welding is one of the most popular metal fabrication processes among crafts enthusiasts. The process of welding involves the joining of two separate metal parts. Welding is achievable through numerous methods and tool types.
Often, a weld is achieved through the application of heat along the points where the two pieces are meant to be joined. A lot of metalworkers first pursue the area of metal fabrication with welding projects in mind. When a machine is used to remove portions from a piece of metal, the process is known as machining.
Typically, the process is performed on a lathe, which will rotate the metal against tools that trim corners and edges to cut the piece down to a desired shape or measurement. In other machining applications, a hole or set of holes will be formed directly through the metal surface.
As such, the metal drill could be classified as a machining tool. When holes are formed in a piece of metal, the process involved consists of punching, where metal is placed under a die and submitted to a punch-through by a drill. For the punch to be the correct size, the circumference of the drill must slot correctly through the die. Punching falls into one of two sub categories based on the intention of a given application. In most cases, the intent is to punch holes into a panel of metal for the purpose of fastening latches or other foreign parts.
In other applications — alternately known as blanking — the area with the hole is specifically extracted from the larger panel to form a smaller bit part.
For sheets of metal that require long cuts, the process is known as shearing. In some cases, the sheet is fed horizontally through a metal-cutting machine. In other applications, a cutting tool is applied vertically against the length of a flat metal sheet. A third method involves placing the metal over the edge of an open cutter and lowering the blade, much like the paper cutters found at copy facilities.
Shearing is often applied to trim down the edge of a metal sheet, but the process may be done anywhere along the metal. Punching is not the only metal fabrication process to utilize a die. In some applications, however, the intention is not to form a hole, but to raise a certain portion of a metal sheet, without penetrating.
For applications like these, the process of stamping is used to form certain shapes, letters or images within a metal sheet or panel. In effect, metal stamping is similar to relief carving in wood or marble. A primary example of metal stamping is seen on coins, where words, currency amounts and the faces of presidents are stamped from each surface side on pennies, nickels, dimes and quarters.
One of the oldest types of metal fabrication involves casting, where molten metal is poured into a mold and is left to solidify into a specific form. As one of the most flexible methods of metal fabrication, casting is ideal for a wide range of complex shape-making.
In some cases, casting provides a solution to fabrication problems that would otherwise take several other methods to solve, such as with assembly parts that would need folding, shearing, and stamping. The most common metals employed in this application include steel, iron, gold, copper, silver, and magnesium.
In most cases, a project will start with one or more of the following materials: Expanded metal. For machines and fixtures needing metal panels that are grated instead of solid, metal is expanded to take on the desired consistency.
Basically, sheets of metal are sheared in a pattern that forms diamond-shaped holes along the surface, which is held together by the remaining mesh-like metal.
As the final formation of each sheet takes place, the metal is effectively expanded to its ultimate dimensions. Expanded metal is commonly used as a protective wall on machines that need ventilation, such as along back-portion panels of computers and heaters.
Panels of expanded metal are also commonplace on the fences and screen doors of condominium complexes and gated communities. The grating size on different sheets of expanded metal may vary, though wider holes are generally favored as a fencing material, and smaller holes are often better for panels on electronics equipment. Expanded metal is also available in a variety of thicknesses. Sectional metals. In the construction and engineering sectors, metals are regularly ordered in sectional varieties for numerous applications.
A construction company, for example, could need structural framing panels of particular lengths and widths, the measurements of which would be standardized throughout the industry and pre-fabricated for order from a construction-parts supplier.
Common types of sectional materials include: I-beam. An I-shaped, cross-sectional beam. A sectional piece shaped similarly to the last letter in the alphabet. A rectangular cross-sectional metal piece. A long sectional metal piece, either square or round.
Flat metal. For any given number of applications, flat metal pieces are used in construction and industrial assemblies. Flat metal is a raw material that is fabricated in a range of thicknesses.
While the pieces are generally thin, the gauge will range from under a millimeter to two or more centimeters. Flat metals typically fall into three groupings: Leaf metal. The thinnest kind, also known as foil metal. Sheet metal.
The most widespread kind, which tends to be under 6mm thick. Plate metal. The thickest kind, which exceeds 0. In this industry, fabricated metals are used to form the structures of buildings large and small.
In the construction of modern skyscrapers, structural beams made of fabricated metals have made it easier to erect buildings from the ground on up to completion in record time. Best of all, fabricated metals make buildings structurally more sturdy and fire-resistant. Boiler, Tank and Shipping Container Manufacturing. In the shipping industry, metal is used in virtually everything, from the assembly parts that make up a ship to the fasteners that hold everything together.
Furthermore, the shipping industry is involved in the transfer of untold tons of fabricated metals on an annual basis. Metal, in effect, could be seen as the driving force of the shipping industry.
Other Fabricated Metal Product Manufacturing. If a list were to be compiled of all the commercial and industrial machines, products and parts that consist of metal, it would probably fill up an encyclopedia. Fact is, metals are produced every day throughout the world for numerous different uses, and in many cases, metal fabrication itself serves as the backbone for the industry in question, whether a company manufactures metal products or relies on products made of metal for virtually everything.
Spring and Wire Product Manufacturing. Wire is intrinsically important to custom metal fabrication processes because welding wires are often used to help weld pieces of metal together in various products. Specialty Manufacturing. Metal fabrication is used in OEM original equipment manufacturing parts, which are used in specialty manufacturing environments. By extension, the auto repair industry benefits from here, because it allows faltering cars to be replaced part by part.

Materials processing , the series of operations that transforms industrial materials from a raw-material state into finished parts or products. Materials processing by hand is as old as civilization; mechanization began with the Industrial Revolution of the 18th century, and in the early 19th century the basic machines for forming, shaping, and cutting were developed, principally in England. Since then, materials-processing methods, techniques, and machinery have grown in variety and number. The cycle of manufacturing processes that converts materials into parts and products starts immediately after the raw materials are either extracted from minerals or produced from basic chemicals or natural substances. Metallic raw materials are usually produced in two steps. First, the crude ore is processed to increase the concentration of the desired metal; this is called beneficiation.
Mill scale. Laser scale. Heat-treat scale. And did we mention heavy mill scale? When these come between your structural steel and your paint or coating, bad things happen. And when the steel you fabricate holds up bridges, overpasses, buildings, and stadiums, bad things are big bad things. So what are structural steel fabricators doing about surface preparation, and what options are available? Surface preparation can run from simple chemical cleaning to abrasion methods such as grinding and abrasive blasting. How to know which methods to use?
