Abstract

The digital image correlation (DIC) method was combined with finite element simulation to describe the high temperature strain evolution of gas tungsten arc welding (GTAW). The DIC method was adopted to get the strain evolution at a high temperature heat affected zone. Then, the finite element modeling method of the ABAQUS software was used to simulate the temperature and strain fields of heat affected zone (HAZ). The results were compared with the results of the DIC measurement. By calculating HAZ strain measurement, the feasibility of the DIC method in describing high temperature strain and the rationality of the finite element model were validated.
