Abstract
This work compares the welding of 5-mm-thick AA5052 H-32 butt welds using pulsed gas metal arc welding (P-GMAW) and cold wire pulsed GMAW (CW-P-GMAW). Welding metal transfer was studied using high-speed imaging in conjunction with synchronized current and voltage acquisition. After welding, the joints were characterized through radiographic examination and standard metallography. The results have successfully demonstrated the feasibility of CW-P-GMAW welding AA5052 H-32. Additionally, the results suggest that the introduction of cold wire feed with pulsed current affects the temperature distribution and reduces the cooling rate of the welding pool accounting for reduced hardness and coarser microstructure.
