Abstract

The welding temperature field of magnesium alloy AZ31 welded by TIG was measured with the uncooled infrared (IR) thermal imaging technology. The variables in the mathematic mode of welding temperature fields were revised by IR temperature data. Based on the results of simulation, the loss of temperature fields caused by arc interfered was compensated, and a whole temperature field was achieved, which provided a precise and powerful foundation for the investigation of microstructure of the joints.
