The electroarc welding of two thin plates is investigated in the work. The mathematical model of a problem is chosen as a biphase Stefan problem in bidimentional area. The convective member in the equation of heat conductivity is approximated by the unilateral difference relation " against a stream ". The numerical realization of mathematical model is carried out with use of an iterative method of the connected gradients.
