Metalworking is a procedure of shaping and forming metals to create various objects, structures, equipment parts, and tools. These projects usually fall under the categories of joining, cutting, and forming. It may involve methods like molding, casting, welding, and cutting. Materials used for this process include non-ferrous and ferrous substances like iron, bronze, silver, gold, aluminum, steel, and more.

Metalworking history

For many centuries, precious metals have been valued and worked into objects by many ancient civilizations, from the Mayans of North America to Kings and Pharaohs of Asia. The oldest known evidence of this artwork is a copper pendant discovered in Mesopotamia or modern Iraq that dates back to 8,000 BCE.

It has been a practice for many civilizations to communicate religious beliefs, status, as well as symbolism through beautiful artifacts. It is a practical way to create structures and tools. It has been practiced by contractors, alchemists, blacksmiths, artisans, and more professionals around the world. All of these individuals specialize in various facets of metalworking.

A lot of ancient metalsmithing methods are still used by today’s metalworkers, from welding to soldering. Metallic ores have been obtained from the earth for many centuries, placing a lot of importance on metalworkers as the source of extracting substances.

For instance, people can remove iron from mineral-rich sand and excavate valuable metals such as silver. In today’s world, these things have become more important to the advancements in transportation and technology and to humanity in general. This industry is all around us today, from the fabrication of automobiles and daily electronic devices.

Metalworking techniques

These techniques create everything from large-scale structures to small decorative things. While a lot of these techniques will almost be the same even if you use different materials, the properties of substances you are using will have a considerable impact on the work and the desired finished result.

Cutting

It will remove substances from materials using routing, milling, turning, as well as technologies like computer numerical control (CNC) machines. Plasma cutters are torches that are powered by gas like hydrogen and argon. It will remove materials and make various sizes of holes in the sheets. Cutting is usually used in fabrication shops, constructions, and automotive repairs.

Forming

This technique is a process of fabricating and re-shaping metals without removing and adding materials. It is possible through a combination of pressure and heat. Both bending and forging are very important methods of forming items. When forging, people will heat it in their forge, then bend and hammer it into their desired shapes and sizes.

To make a curve or bend in materials, apply heat using the forge and hold it over the anvil horn, then strike it with a mallet or hammer to make the desired curve. English wheels are tools that allow workers to shape and form cold materials like steel or aluminum easily.

Joining

This technique is a process of combining pieces of metals with heat by soldering or welding. Welding is an exceptional fabrication process that uses welding machines to join non-ferrous and ferrous stamped metal parts or materials. It works well for more significant objects.

On the other hand, soldering is a joining technique used to merge various types of precious metals by melting solder. It works well for smaller projects like jewelry making. Modern technology continues to evolve as metalworking techniques advance.

Casting

Casting is a process that can be traced back to ancient civilizations, more or less 4,000 BCE. It is still used for making tools, jewelry, or sculptures. Since they learned how to melt various metals, people have been pouring molten substances into molds or cavities shaped in plaster, stone, sand, or bones. Casting is time and cost-effective, and it provides individuals with the ability to create more than one item with the same design.

Common techniques for casting metals are sand and lost wax casting. Lost wax castings involve shaping or carving pieces in certain wax and creating plaster molds. After shaping the design, the wax is then burned. Sand castings use sand as a medium. It is then combined with a bonding agent, usually clay, and is gated. Molten substances, then flow into the pre-made mold to make a solid object.
