Hot work is a process that can be a source of ignition when flammable material is present or can be a fire hazard regardless of the presence of flammable material in the workplace. Common hot work processes involve welding, soldering, cutting, brazing burning and the use of powder-actuated tools or similar fire producing operations outside of designated hot work areas. When flammable materials are not present, industrial processes such as grinding and drilling become cold work pro… WebDefinition of Hot Working: Mechanical working of metals can be carried out in the form of either hot working or cold working. Working above the recrystallization temperature (lower critical temperature) but below the burning point is termed as hot working. The metals are given desired shape in hot working process by subjecting them to forces ...

Hot Forging Process and Its Applications Steel Forging
WebHot working. First, the raw material in the form of large ingots or billets is hot-worked, usually by rolling, forging, or extrusion, into smaller shapes and sizes. Historically, metalworking posses one of key domains in materials science. It is the process of working with metals to create individual parts, assemblies, or large-scale structures. WebCold, Warm and Hot ForgingHot forging is the plastic deformation of metal at a temperature and strain rate such that recrystallization occurs simultaneously with deformation, thus avoiding strain hardening. For this to occur, high workpiece temperature (matching the metal’s recrystallization temperature) must be attained throughout the … WebHot work is any process that generates flames, sparks or heat. It includes welding, cutting, grinding and sawing and particularly the application of heat to free rusted on bolts etc. When a wheel rim or other steel part of a vehicle wheel is subjected to heat, there is a risk that any tyre (inflated or deflated) attached to it will explode. marketplace 84
