The actual cooling rates in electron-beam welds for carbon steel, stainless steel, aluminium plates and zirconium sheet are compared with the theoretical cooling rates which are induced by the thermal conduction theory. According to this comparison, the actual cooling rates in the elec-tron-beam welds which show unique wedge-shape penetration agree with the theoretical cooling rates by the two-dimensional heat flow theory.<BR>Especially at the temperature below 900°C, the actual cooling rates and cooling curves in the electron-beam welds completely agree with those induced from the theoretical equation.<BR>With utilization of this theoretical equation, therefore, a nomograph from which is estimated the cooling time from 800°C to 500°C is made for a carbon steel of which the weld metal and heat affected zone are hardened when electron-beam welding is done. Moreover, the method for the estimation of hardness in the electron-beam welds is established with the use of the nomograph and C.C.T. diagram for welding and is discussed for the reliability. As a result of the discussion, it is seen that the above method for the estimation is reliable for carbon steel.
