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 ۳۱۰S) was 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 and performed in L۱۱ without experiment replication. According to a Scanning Electron Microscope (SEM) images from the experiments, changes in three effective parameters were obtained. The voltage and wire feed rate had the most significant impact on increasing HAZ and ultimately the diffusion depth due to the increase of heat generated and the creation of a more comprehensive Weld Pool (WP). Experimental ۱۱-samples was used by NI vision IP software to find the diffusion depth and surface zone of the HAZ. Results of the effect parameters in Image Processing and Simulation software showed validation for evaluating changes in HAZ.
