Heat treatment of welded joints - Part 1 - Job Knowledge 114

Welding involves the deposition of molten metal between two essentially cold parent metal faces. As the joint cools the weld metal contracts but is restrained by the cold metal on either side; the residual stress in the joint therefore increases as the temperature falls.

What is Annealing? Heat Treatment of Steels - Annealing

brighthubengineering› …› Manufacturing TechnologyAnnealing is a process by which the property of steel is enhanced to meet the machinability requirements. Annealing is a process of heating the steel slightly above the critical temperature of steel i.e. 723 Degree Centigrade and allowing it to cool down very slowly.

Normalizing Process for Steels | ispatguru

Normalizing Process for Steels. Normalizing process for steels is defined as heating the steel to austenite phase and cooling it in the air. It is carried out by heating the steel approximately 50 deg C above the upper critical temperature (AC? for hypoeutectoid steels or Acm in case of hypereutectoid steels, Fig 1) followed by cooling in air to room temperature, or at no greater than 1 bar ...
