Technology in general, and automation in particular, tends to exert pressure against laborer-type job creation, with the lowest-skilled positions being most at risk. For example, so-called labor gangs, groups of men assigned to shoveling or other manual tasks, are not employed nearly as much as they used to be, especially in developed economies.
A steel detailer is a person who produces detailed drawings for steel fabricators and steel erectors. The detailer prepares detailed plans, drawings and other documents for the manufacture and erection of steel members (columns, beams, braces, trusses, stairs, handrails, joists, metal decking, etc.) used in the construction of buildings, bridges, industrial plans, and nonbuilding structures.
Metalsmiths today still use this and many other ancient techniques. 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.
Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added [1] process involving the creation of machines, parts, and structures from various raw materials. Typically, a fabrication shop bids on a job, usually based on engineering drawings, and if awarded the contract, builds the ...
Coppersmith Abdón Punzo in his workshop in Santa Clara del Cobre, Mexico "Aeolus's Weathervane" – detail of a weather vane created by using a variety of metalsmithing techniques The ancient traditional tool of the smith is a forge or smithy , which is a furnace designed to allow compressed air (through a bellows ) to superheat the inside ...
The energy from the impact plasticizes the materials, forming a weld, even though only a limited amount of heat is generated. The process is commonly used for welding dissimilar materials, including bonding aluminum to carbon steel in ship hulls and stainless steel or titanium to carbon steel in petrochemical pressure vessels.

To hoist the steel, structural ironworkers use cables connected to the crane to lift the beams onto the steel columns. A rope called a tagline is attached to the beams so an ironworker can control them when needed. The crane hoists steel into place, and the ironworkers position the beams with spud wrenches to align bolt holes.
A steel circular brush is attached to an angle grinder and used to remove the first layer leaving behind a bumpy surface similar to hammered bronze. In the glass industry for "fire polishing". In jewelry production for "water welding" using a water torch (an oxyhydrogen torch whose gas supply is generated immediately by electrolysis of water).
