This could be directly, such as from an open flame, or from anything that will create a spark, such as cutting metal with an angle grinder, or something that generates extremely high temperatures, such as using metal pipes as a conductor. Hot work …
WebbWarm working may be preferred over cold forming because it will reduce the force required to perform the operation. Also, the amount of annealing of the material that may have been necessary for the cold formed part may be less for warm working. Hot Working. Hot working, (or hot forming), is a metal forming process that is carried out at a ... WebbDuring hot working, the grains are distorted, elongated with increased imperfections, but simultaneously the processes of dynamic recovery, recrystallisation, and even grain growth (if the temperature of piece is very high) take place. Thus, on a broad basis, hot working is equivalent to cold working and annealing.
