As time progressed, metal objects became more common, and ever more complex. The need to further acquire and work metals grew in importance. Skills related to extracting metal ores from the earth began to evolve, and metalsmiths became more knowledgeable. Metalsmiths became important members of society.
Some jobs, despite being classifiable as semiskilled work, actually require quite a bit of talent and experience to be done well, for example, band saw operators or buffing and polishing workers. Rigger, a person specializing in the skills needed to move large, heavy objects
South American metal working seems to have developed in the Andean region of modern Peru, Bolivia, Ecuador, Chile, and Argentina with gold and native copper being hammered and shaped into intricate objects, particularly ornaments. [1] [5] Recent finds date the earliest gold work to 2155–1936 BC. [1] and the earliest copper work to 1432–1132 BC.
Smelting involves more than just melting the metal out of its ore. Most ores are the chemical compound of the metal and other elements, such as oxygen (as an oxide), sulfur (as a sulfide), or carbon and oxygen together (as a carbonate). To extract the metal, workers must make these compounds undergo a chemical reaction.
Shaping metal with a hammer is the archetypical component of smithing. Often the hammering is done while the metal is hot, having been heated in a forge . Smithing can also involve the other aspects of metalworking , such as refining metals from their ores (traditionally done by smelting ), casting it into shapes ( founding ), and filing to ...
Brazing is a metal-joining process in which two or more metal items are joined by melting and flowing a filler metal into the joint, with the filler metal having a lower melting point than the adjoining metal. Brazing differs from welding in that it does not involve melting the work pieces.
