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.
