Abstract :
In this research, the effect of diffusion depth and Heat-Affected Zone (HAZ) in Nanoparticles-Electrode Gas
Metal Arc Welding (NE-GMAW) process with carbon dioxide protection on Heat Resistance Steel (SUH
310S) were investigated using the Image Processing (IP) and simulation software. Welding speed (S), Wire
feed rate (F) and Voltage (V) as effective parameters were considered for experimental tests. The Design of
Experiment (DoE) was using the Taguchi method with L11 array without experiment replication. According
to the Scanning Electron Microscope (SEM) images of the experiments, changes in three effective parameters
were obtained. The voltage and wire feed rate had the most significant impact on increasing HAZ zone and
ultimately the diffusion depth due to the increase of heat generated and the creation of a more comprehensive
Weld Pool (WP). The experiments with 11-samples were used to find the diffusion depth and surface zone
of the HAZ region by NI vision IP software. The effect of parameters in image processing and simulation
software in results showed validation for evaluating changes in HAZ zone.
