Abstract

Non-consumable electrode welding is widely used in manufacture, construction and other areas. Despite progress in welding technology and the emergence of new methods of joining materials, non-consumable electrode welding is confidently occupying its niche in the production area. In this work we consider the problem of optimal design in non-consumable electrode welding based on the solution of the inverse heat transfer problem by means of parallel computations. Heat transfer problem is solved by finite difference method for orthogonal geometry in transient mode. Authors used their own program, called the “Welding engineer virtual workplace” which is developed in Matlab. In this work we present the basis for solving the inverse heat transfer problem and an algorithm of parallel searching for the optimal technological parameters of the non-consumable electrode welding. The final result of design is based on a collective decision-making approach.
