Abstract
Aluminum alloy welding wire ER5356 was welded on galvanized steel plate by Pulsed DE-MIG. The best welding seam morphology was got by adjusting Pulsed DE-MIG welding parameters. It indicated that welding-brazing of aluminum-galvanized steel dissimilar metals were achieved by Pulsed DE-MIG. SEM and EDS were adopted to observe and analyze the interface microstructure of welding joints. The results indicated that two intermetallic compounds layers of Fe2Al5 and FeAl3 formed along the interface of aluminum-steel. And models of interface reaction of aluminum-steel dissimilar metals were put forward.
