概要

Temperature curve of any point on thin mother plate due to linear moving point heat is compared with that due to the heat delivered along a straight line instantenuously at t=0. Fig. 10 shows the former for points near arc starting point in form of n-X scale which are defined in equ. (1), (2) and (30). Fig. 2 shows shows the latter in form of m-t/τ scale defined in equ. (9) and (14). The curves in Figs. 2 and Fig. 10 are expressed using a common scale in Fig. 12,the relation of conversion of scales is given in equ. (32). Fig. 13 shows those of points along bead line. Form Fig. 12 and 13 we can clearly see the difference of temperature curves between moving point heat source and instantenuously delivered heat. It is well known experimentally that the maximum temperature of point near bead end is higher for arc stopping side compared with arc starting side. The graphical explanation is given using Fig. 14 and 15.
