metalworks

Metalworks refers to the craft and industry of shaping and assembling metal to create components, structures, tools, and artwork. It encompasses both traditional handwork and modern industrial processes, spanning from personal smithing to large-scale fabrication and manufacturing.

Historically, metalworking began with brazing, smithing, and simple casting in the Bronze and Iron Ages. The development of machine tools in the 18th and 19th centuries amplified precision and scale, enabling railway, shipbuilding, and machinery industries.

Core techniques include casting, forging, extrusion, rolling, and machining. Joining methods such as welding, soldering, and brazing fuse parts. Finishing processes like cutting, deburring, grinding, polishing, and coating improve surface quality and corrosion resistance. Additive manufacturing using metal powders has expanded capabilities.

Metals used include ferrous metals like steel and cast iron, and nonferrous metals such as aluminum, copper, brass, and titanium. Alloys are engineered to achieve specific strength, ductility, hardness, and temperature resistance.

Metalworks support construction, transportation, machinery, and consumer products. In industry, fabricators produce structural components, pressure vessels, and machine parts. In art and jewelry, metalworking emphasizes form, texture, and finish.

Workers face hazards from sharp edges, heated surfaces, molten metal, and heavy equipment. Industry standards from organizations such as ISO, ASTM, and AWS guide material selection, testing, welding procedures, and safety practices.

Today, metalworking combines skilled craftsmanship with computer numerical control (CNC) machining, robotics, and automation. Shops may focus on fabrication, precision machining, or specialty processes, and the field continues to evolve with advances in materials and sustainable manufacturing.
