Let's Explore 27 Powerful Types of Metalwork Used By Metalworkers Today
Metalworking is the intricate process of forming and shaping different metals to fit various industrial, structural, and decorative applications. It alters the shape, size, and thickness of crude metal, transforming it into a usable, valuable object. Metalworkers extract and reshape ferrous and non-ferrous metals to fabricate useful products like hand tools, building components, and engine parts, among other items. However, raw metal materials must undergo different types of metalwork to obtain the desired outcome. Here is a comprehensive breakdown of different types of metalwork.



Forming
Forming is one of the oldest types of metalwork. It entails reshaping or modifying raw metal parts and objects without removing or adding any material. The process combines extreme heat and mechanical pressure to deform a metal workpiece into the desired shape or application.
Most metalworkers rely on hand tools, such as anvil horns and hammers, for small-scale production. On the other hand, large-scale industrial metalwork projects use modern machinery and require high mechanical force to achieve the appropriate form.
Forming has several manufacturing subprocesses. Metalworkers combine these processes to manipulate metal sheets and bars into various shapes and dimensions and enhance their mechanical properties. Primary forming techniques include the following:
Drawing
It utilizes tensile forces to extend the length and reduce the cross-sections of sheet metals, wires, and rods over a die.
Rolling
Rolling is a metalwork type that uses compressive forces to reduce the thickness of a metal workpiece. It entails passing the metal material through rotating rolls to change its shape or make the thickness more uniform.
Forging
Forging is an age-old technique that uses local compressive forces to reshape a metal workpiece. During forging, a metalworker will pass the workpiece over high heat and then hammer it into the preferred shape. Cold forging is possible for specific metals and materials.
Bending
Bending is a forming process that transforms the shape of a ductile metal workpiece without altering its volume. Typical bending equipment includes brake presses and specialized machine presses.
Stamping
Stamping is a precise and efficient type of metalwork that entails pressing sheet metal into the desired shape using a machine press and die. Its applications range from aerospace to automotive industries.
Extrusion
Extrusion is a transformative type of metalwork that involves forcefully passing a metal billet through a die to change its cross-sectional shape. The aim is to produce metal objects with fixed cross-sectional profiles.

Drill Press

Cutting
Cutting is a fundamental metalworking process that removes unwanted or excess materials from a metal workpiece. This type of metalwork is also ideal for cutting large metal sheets into smaller, manageable pieces. The process uses various tools and technologies to achieve the intended shape or dimensions with utmost accuracy.
Metalworkers employ cutting processes for various applications. Cutting is fundamental in manufacturing machinery components and precision parts. It is also ideal for creating prototypes before mass production of a refined design.
Like other types of metalwork, cutting has several techniques and subprocesses. These processes have distinct applications. The primary cutting methods and techniques in metalworking include the following:
Milling
Milling is the removal of excess material from a metal workpiece using a milling machine. The machine has a high-speed rotating cutter that moves in multiple directions to cut unwanted material from the stationary workpiece to produce precise shapes and designs.
Grinding
Grinding machines remove unwanted material from metal pieces through abrasion. These machines have abrasive wheels that make light cuts and fine finishes when applied to a metal workpiece. Metal grinders range from bench grinders and handheld grinders to CNC (computer numeric control) grinding machines.
Drilling
It involves creating holes in a metal workpiece using a drill press or handheld drill. Metalworkers can also use CNC machines to make smooth and accurate holes in raw or finished metal workpieces.
Turning
Turning is a metalworking method that uses a stationary cutting tool against a rotating metal workpiece to remove excess material. The workpiece rotates on a lathe while the stationary cutting tool removes unwanted material symmetrically to produce conical and cylindrical shapes.
Threading
Machining
Machining is a subtractive technique that uses specialized automated machines to cut and remove excess or unwanted materials from metal workpieces. It transforms raw metal materials into high-precision parts and components.
Laser Cutting
Laser cutting is strikingly similar to machine cutting. However, it employs laser technology rather than mechanical machines to cut metal pieces. The primary advantage of laser cutting is that it is fast. It also produces smooth and accurate results.
Filing
Filing is one of the oldest metalworking techniques for removing excess material. It involves using a file to work on small metal workpieces. However, with the emergence of modern tools, metalworkers rarely use this method.
Broaching
Broaching utilizes a toothed cutting tool to cut keyways into shafts and remove metal pieces. It can be linear or rotary and is ideal for making gears and splines.
Casting
Casting is a type of metalwork that involves heating metal until it reaches its melting point before molding it into the desired shape. Metalsmiths pour molten metal into cavities, allowing it to cool and solidify into the intended shape. Once cooled, the metalworker will extract it from the cavity and conduct the necessary finishing processes.
This metalworking process traces its roots to 4,000 BC, making it one of the oldest types of metalwork. It is suitable for creating complex shapes in a single-volume run, given that it is time-effective. Casting is also ideal for making sculptures, agricultural equipment, and handheld tools. Unlike other types of metalwork, casting does not require mechanical force.
There are several types of casting processes. The ideal casting method depends on the type of metal and project scope. They include:
Investment (Lost Wax) Casting
It entails crafting a wax pattern coated with ceramic materials. When the ceramic solidifies, the metalsmith melts the wax away, leaving a mold or cavity. The last step involves pouring the molten metal into the mold and allowing it to cool and harden.
Die Casting
Die casting uses high pressure to forcefully push molten metal into a mold. This method is ideal for casting complex shapes and designs.
Centrifugal Casting
Centrifugal casting utilizes centrifugal force to push molten metal into a rotating mold. It thrusts the molten metal against the mold’s walls, resulting in uniform, cylindrical casts.
Sand Casting
Sand casting uses a blend of sand and bonding agents to create a cavity. The metalsmith then pours molten metal into the created mold.
Shell Casting
Shell casting uses resin-covered sand to create a mold. It is similar to sand casting but has higher dimensional accuracy.
Joining
Joining is another broad type of metalwork. This metalworking method combines several metal pieces into one large workpiece. A metalsmith may join ferrous and non-ferrous metals by applying heat and pressure with filler materials to create robust joints. This process is ideal for metalworking projects that require large workpieces. Metalworkers can use various joining techniques to achieve the desired outcome. The most common types of joining methods include:
Welding
Welding is a fabrication process used for joining metals by causing coalescence. It combines heat and pressure to fuse separate metal materials into one. A metalsmith may melt the workpieces before adding a filler material to create a sturdy joint once the molten metal cools and hardens. While there are over four types of welding, they all share a similar working principle.
Soldering
Soldering is a common joining process that involves heating and melting a low-temperature alloy (solder) into a joint to fuse two or more metal workpieces. Metalsmiths often use a soldering iron or gun to melt the filler material into a capillary, forming a joint.
Riveting
Riveting involves using rivets to join multiple metal workpieces. A rivet is an unthreaded bolt that creates a kinetic joint in a metal workpiece. It holds to metal sheets permanently but requires the metalsmith to drill holes in the workpieces before punching the rivets into place.
Brazing
Brazing is a joining process similar to soldering. However, it utilizes high temperatures to melt filter material, resulting in a robust metallurgical reaction between the filler and metal workpiece. The filler metal cools and solidifies, resulting in a strong joint.
Mechanical Fixing
Other joining methods entail using screws, bolts, and adhesives. These techniques are slightly weaker than welding, brazing, or soldering. However, they do not require specialist knowledge or sophisticated equipment.
Metalworking remains integral to the manufacturing sector. It has an essential role in industrial, structural, and decorative applications. Learning the different types of metalwork can help you select the appropriate technique for your project or application. Each technique has a distinct purpose. However, most metalwork methods are versatile but may rely on other metalwork techniques to achieve the desired finish.
