What Is Metal Fabrication?
Metal fabrication creates products or structures by cutting, bending, and assembling metal materials. It uses raw materials such as metal sheets, expanded metal, welding wires, and rods to construct various components.
The fabrication process requires precision and expertise in working with different types of metals, like stainless steel, which gives sturdy results. It typically consists of three main steps:
- Design
- Fabrication
- Installation
Design: During the design stage, detailed plans are developed. Moreover, measurements and specifications are outlined for the project.
Fabrication: Machines cut, bend, and shape the metal material in the fabrication stage into desired shapes.
Installation: After proper fabrication comes installation, where all components are partially or fully assembled based on requirements.
Common Metal Fabrication Techniques
Regarding metal fabrication, various techniques are used to transform raw metal into finished products. Such techniques are crucial in creating durable and complex metal structures, from cutting to welding.
Here are some standard metal forgery techniques that are used in industries worldwide.
-
Forging
When it comes to intricate metalwork, forging is widely used. The forging process involves applying forced compression to shape the metal as desired. Forging is typically done manually. It requires heating the metal until it becomes pliable enough to be shaped using hammer strikes or dies.
With origins dating back centuries, forging remains popular among blacksmiths and fabricators, especially for creating detailed and artistic pieces today.
Its versatility makes it an essential technique in automotive manufacturing, aerospace engineering, and construction projects. Such projects require durable components made from various metals, like steel or aluminum alloys.
-
Casting
Casting is a popular technique for manufacturing large quantities of identical items efficiently. In casting, molds are filled with liquid metal to create customized shapes for various automotive, aerospace, and construction industries.
In casting, molten metal is streamed into a mold. The metal then cools and hardens. Hardening creates mass-produced products with minimal variance in the outcome.
The overall casting process allows for precision and consistency in producing high-quality scaled parts using materials like stainless steel or aluminum alloys.
-
Drawing
Concerning metal forgery, drawing involves pulling and stretching metal with force to create tapered shapes. It is commonly used to produce box-like or cylindrical vessels in metal fabrication.
-
Forming
During forming, the metal is bent to achieve a desired angle. It’s typically done using a brake press, which applies pressure and creates creases in the metal.
Alternatively, clamp bars can be used with a hammer for folding purposes. The forming process helps create custom shapes and angles in metal fabrication projects. The result is versatile and durable products for various industries that rely on precise forming techniques.
-
Machining
Machining is a subtractive process that shapes metal by removing excess material. It includes drilling, turning, and milling techniques.
Turning involves spinning the metal on a lathe while cutting tools remove it in circular motions. CNC machines are commonly used for precise measurements during this process.
Drilling uses bits to create holes in the metal—a straightforward technique.
Milling is often used as a final finishing step that removes metal from workpieces using multi-point cutting tools. Milling helps achieve specific textures or appearances desired by customers.
-
Extrusion
A metal extrusion technique involves forcing metal through an opened or closed die to reduce its size or shape to match. This process creates cylindrical shapes commonly used for piping or wiring in industries such as construction and manufacturing.
-
Cutting
Cutting involves precision and various technologies. Laser cutting, plasma, waterjets, and power scissors are commonly used to achieve accurate cuts on different projects.
A versatile process like cutting efficiently transforms large pieces of metal into smaller parts. In many cases, cutting is the principal technique throughout the fabrication process.
-
Punching
Punching creates holes in a workpiece using punch presses. The punches hit the metal through dies to produce holes in specific locations. Punching is used for light and heavy metalwork, making it versatile.
-
Stamping
Stamping is similar to punching. It uses a press or handheld hammer to create indentations in metal, not holes. Stamping is commonly used for creating letters, shapes, and images on metal surfaces.
-
Welding
The process of joining metal pieces by using heat and pressure is welding. It is commonly used in large-scale projects due to its versatility in merging metals of different shapes and sizes.
The most popular types of welding techniques include MIG, stick and arc, TIG, and flux-cored arc. Welding is crucial in various industries, such as construction, automotive manufacturing, shipbuilding, etc. This technique helps metal fabricators create durable metal structures for different applications.
The Different Kinds of Metal Fabrication
Various types of metal fabrication are applied in multiple projects. Here’s a look at different kinds of metal fabrication used in various industries.
-
Industrial Metal Fabrication
Fabrication of industrial metal products involves integrating parts or assemblies into industrial products using sheets or plates of metal. It is used in various industries like aerospace, energy, automotive, and more.
Products like large tanks, silos, and heavy machine parts are typically made in larger quantities and sizes. Steel and stainless steel create durable structures for industrial applications using cutting, welding, and forming techniques.
-
Structural Metal Fabrication
Fabrication of structural metal creates strong and durable metal parts used in construction projects. Steel, known for its strength-to-weight ratio, is commonly used in structural applications.
Examples of forged structural metal parts include I-beams, stairs, walkways, trusses, and rafters. Fabricators shape raw materials into these essential structural components using gas metal arc welding (GMAW) processes.
With precision sheet metal forgery methods, structural engineers efficiently fabricate intricate designs. Such ease makes it a crucial part of today’s construction industry.
With total revenues averaging around $33 billion annually, the fabricated structural metal manufacturing industry was significant in the United States in 2018. From 2012 to 2017, this industry experienced moderate growth with an annualized compound rate of 2.8%.
In 2018, approximately 3,000 firms were actively involved in fabricated structural metal manufacturing in the country. This thriving sector also provided employment opportunities for about 95,000 individuals.
-
Commercial Metal Fabrication
Commercial metal fabrication is crucial in various commercial facilities, such as restaurants and retail stores. The two popular categories of commercial metal forgery are decorative and ornamental. Products like awnings, guardrails, shelves, appliances, sinks, and conveyors are commonly forged commercially.
The fabricated products tend to be smaller yet precise in their purpose compared to industrial or structural applications. Commercial metal fabrication offers customized solutions that enhance industrial or structural spaces’ functionality and aesthetics.
