Forging a nail. Valašské muzeum v přírodě, Czech Republic. Forging is one of the oldest known metalworking processes. [1] Traditionally, forging was performed by a smith using hammer and anvil, though introducing water power to the production and working of iron in the 12th century allowed the use of large trip hammers or power hammers that increased the amount and size of iron that could ...
Forging uses heat to bring the material to a malleable state. The material is then hammered to shape, typically using hammer and anvil together with specialized set and fuller tools depending on the particular technique. There is a variety of forging techniques for sword making and many variations upon those. Ceremonial swords from the Philippines.
Swaging. Swaging (/ ˈsweɪdʒɪŋ /) is a forging process in which the dimensions of an item are altered using dies into which the item is forced. [1] Swaging is usually a cold working process, but also may be hot worked. [2] The term swage may apply to the process (verb) or to a die or tool (noun) used in that process.
Forge welding. Forge welding (FOW), also called fire welding, is a solid-state welding process [1] that joins two pieces of metal by heating them to a high temperature and then hammering them together. [2] It may also consist of heating and forcing the metals together with presses or other means, creating enough pressure to cause plastic ...
Punching is a forming process that uses a punch press to force a tool, called a punch, through the workpiece to create a hole via shearing. Punching is applicable to a wide variety of materials that come in sheet form, including sheet metal, paper, vulcanized fibre and some forms of plastic sheet. The punch often passes through the work into a die.
The nursing process is a modified scientific method which is a fundamental part of nursing practices in many countries around the world. [1] [2] [3] Nursing practise was first described as a four-stage nursing process by Ida Jean Orlando in 1958. [4] It should not be confused with nursing theories or health informatics. The diagnosis phase was ...
Donabedian model. The Donabedian model is a conceptual model that provides a framework for examining health services and evaluating quality of health care. [1] According to the model, information about quality of care can be drawn from three categories: “structure,” “process,” and “outcomes." [2] Structure describes the context in ...
Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material. [1][2] Heat is generated by friction between the rotating tool and the workpiece material, which leads to a softened region near the FSW tool. While the tool is traversed along the ...
