Thermal State Simulation of Welded Steel Plates under Laser Welding Conditions

Abstract:

The article describes a method for determination of the welded parts temperature pattern under laser welding conditions. An algorithm is engineered to solve the non-stationary heat conduction problem by finite element method. The boundary conditions are determined by the molten pool parameters and depend on the welding regime characteristics. The dependencies for determining the molten pool geometric dimensions for laser welding conditions are proposed. Calculations of the temperature pattern change during the steel plates joint by laser welding are carried out. It is shown that the proposed model adequately describes the heat transfer process in the welding region.
