As a series of the development for the welding simulator, the authors proposed the system with which any user can compute easily the thermal conduction. If shapes of an object and a preheating region can be drawn on a CRT graphic display, computing the thermal conduction of the drawn object is executed automatically. This system can be applied in the following cases ;(1) two-dimensional heat conduction in a finite object (2) a three-dimensional heat conduction in a finite object with a uniform cross section to the welding direction-The uniform cross section is drawn on the CRT, and a size and heating range to the welding direction are put with the numerical value.(3) a special case of two dimensional heat conduction in several thin plate structures as a box or vessel-The development of the structure is drawn on the CRT. In the case of (1), (2), and (3), a thermal conduction is processed by a use of the finite difference method.(4) a large size plate or a long pipe-A shape of the heating region is drawn on the CRT. Point or line heat sources are distributed in the drawn shape, and the heat conduction is processed by the summation of the analytic solution
