PER-LAYER HEAT INPUT MODELLING METHOD FOR 3D COMPUTATIONAL MULTI-LAYER WELDING ANALYSIS AND WELDING APPARATUS

摘要

PURPOSE: A heat input simulation method and a device thereof are provided to reduce the number of heat input simulation processes. CONSTITUTION: Heat is transferred to a welding direction through the surface of a welding layer(100). Stress generated before arrival of heat is removed in a process that heat arrives in. A heat input is copied by configuring welding bead. Temperature calculation is performed according to a welding process.
