Metalworking encompasses a range of technological processes involving the shaping, modification, and joining of metals and alloys. These techniques utilize principles of thermodynamics and material science, ranging from high-temperature metallurgical processes like smelting and refining to lower-temperature forming methods such as casting, forging, and machining. The manipulation of metals allows for the creation of tools, structural components, and specialized machinery. By controlling parameters such as heat, pressure, and chemical composition, various physical properties, including tensile strength, hardness, and elasticity, can be achieved, making this field foundational to engineering and material technology.
