In this report, calculation of grain size in weld heat affected zone (HAZ) of two-dimensional bead was investigated combining grain growth equation and heat conduction equation. Main results obtained are as follows. (1) Grain size in HAZ calculated using an instantaneous plane heat source is nearly equal to that calculated using a moving line heat source when welding speed is faster than about 12cm/min. (2) Grain size in HAZ can be calculated combining grain growth equation and heat conduction equation with an assumed instantaneous plane heat source. Validity of this method was confirmed on TIG arc welding of commercial-purity nickel and TIG arc and submerged arc welding of steel.
