The article presents tests concerning the content of retained hydrogen present in FCAW and SAW welded joints made of superduplex steel. The use of various welding technologies resulted in the obtainment of welds having different microstructures and ferrite contents. Measurements of retained hydrogen present in joints (performed using the complete combustion method) revealed various contents of hydrogen in the base material and in the welds subjected to the tests. It was determined that the content of hydrogen in welds made of superduplex steels depends not only on the volumetric content of microstructures but also on their composition and welding linear energy.
