These engineering materials in their raw form are extracted from their ores. These raw materials from ores are transformed into molten form through refining and reducing processes. The molten material is process through molds to produce commercial or industrial castings called ingots. These ingots are then processed through rolling to transform these into billets, rods and slabs suitable for marketing. These materials then undergo various manufacturing processes to obtain useful products in diverse range of sizes, shapes and forms desired by end user. According to Singh, these manufacturing processes are classified into six major categories: primary shaping processes, secondary shaping processes, metal forming processes, joining and fastening processes, surface finishing processes and processes to change characteristics and properties of materials (17). In this report, we would be focusing on joining and fastening processes required to assemble or join different parts of a product. The process where two or more parts of the product are put together to achieve desired shape and function is called assembly, not to be confused with joining and fastening processes. In joining, different parts of the product are joined together to obtained desired function. ...
