SIMULATION ON TIG WELDING ARC BASING ON ARC-WELD POOL UNIFORM MODEL

Abstract

Abstract: TIG welding is chosen as the studied object. Arc-weld pool uniform model is established and welding arc is analyzed basing on this model. This model avoided the assumption that anode surface temperature is constant which made simulation on arc more near to real situation and also made the foundation for combining welding arc and weld pool together. ANSYS software is adopted and achieved the varied anode surface temperature with time and current density distribution on anode surface. The distribution of heat flux was in accordant with current density distribution. The main reason causing arc pressure by magnetic force and fluid flow is revealed. Current density and arc pressure distribution are proved by experiments.

Key words: ANSYS, Arc-weld pool, TIG, Uniform model
