Abstract
Obtaining a balanced microstructure in the fusion zone on a super duplex stainless steel (SDSS) weld is a challenge. The present work reports the use of the Watts bath to correct the phase balance on laser-welded SDSS. Three different Watts bath times were used, and the microstructure of the weld bead was evaluated. The Watts bath was efficient to correct the undesirable unbalanced microstructure resulting from SDSS laser welding as the austenite percentage increasedFile in questo prodotto:
