Metalsmiths have been pouring molten metals into cavities shaped in stone, plaster, sand, and even bone since we learned to melt metals. Metal casting is a metalworking process that can be traced back to around 4000 BCE, and it is still used for making sculptures, tools, and jewelry. The English wheel is a tool that allows metalworkers to easily form and shape cold materials, such as aluminum or steel. To make a bend or curve in the metal, heat it in the forge, then hold it over the anvil horn and strike it with a hammer to make your desired curve. When forging metal, you will heat it in the forge, then hammer and bend it into your desired shape. Both forging and bending are essential methods for forming metal. This process is possible through a combination of heat and pressure. Formingįorming is the process of re-shaping and fabricating metal objects without adding or removing any material. New technology continues to develop as metalworking advances. Soldering is a joining process used to fuse different types of precious metals together by melting solder and works well for small projects. Welding is a fabrication process that utilizes a welding machine to join ferrous and non-ferrous metals and works well for larger projects. Joining is the process of combining several pieces of metal with heat through welding or soldering. Cutting is often used in metalworking fabrication shops, automotive repair, and construction. Plasma cutters are gas-powered torches powered by argon and hydrogen gas that will remove material and make holes in metal. CuttingĬutting removes material from metal using milling, routing, turning, and technologies like CNC (computer numerical control) machines. While many metalworking techniques will be similar across different materials, the properties of the metal you are working with will greatly impact your work and your desired finished result. Metalworking techniques create everything from small decorative objects to large-scale structures. Metalworking is all around us, from the fabrication of electronics to automobiles. In modern times, metals have become even more critical to humanity and advancements in technology and transportation. For example, you can remove iron from mineral-rich sand and mine precious metals like silver from the earth. Metallic ores have been extracted from the earth for thousands of years, placing great importance on metalworkers as the source of extricating metals. Many ancient metalsmithing techniques are still used today, from soldering to welding. It has been practiced by artisans, blacksmiths, alchemists, contractors, and more around the world, all of whom specialize in different aspects of metalworking. Metalworking has been a way for civilizations to communicate status, religious beliefs, and symbolism through artifacts and a practical way to build tools and structures. The oldest known evidence of metalworking is a copper pendant uncovered in Iraq and dates back to 8,700 BCE. The history of metalworkingįor thousands of years, precious metals have been worked into objects and valued by ancient civilizations, from Pharaohs in Egypt to Mayans in North America. Materials used for metalworking include ferrous and non-ferrous metals such as steel, aluminum, gold, silver, bronze, iron, and more. Metalworking projects generally fall under the categories of forming, cutting, and joining, and may involve techniques such as cutting, welding, casting, and molding. Metalworking is the process of forming and shaping metals to create useful tools, objects, equipment parts, and structures.
