Abstract: This work purposes to investigate the microstructure and the mechanical behavior ofdissimilar metals weld between 2205 duplex stainless steel (UNS 31803) and high strength lowalloy steel API X52. The joining was produced by shielded metal arc welding process using twodifferent filler metals, the duplex E2209 and austenitic E309 grade.The microstructures of the dissimilar welded joints have been investigated by optical microscopy,scanning electron microscopy and energy-dispersive spectroscopy (EDS). The EDS analysisperformed at the API X52/weld metal interface showed an evident gradient of Cr and Ni betweenfusion and type II boundaries, where the highest hardness value was recorded.
